• Domain Modeling - Encapsulation

  

  Date Published: 18 May 2022

  Domain models should encapsulate logic operations so that there is only one way to perform a given logical operation. That means avoiding exposing entity state and ensuring operations flow through specific methods. By funneling specific operations through specific code pathways, you can be sure constraints around the operations are enforced. In the previous article, I demonstrated some of the…

  
  

• Domain Modeling - Anemic Models

  

  Date Published: 11 May 2022

  When building a domain model, proper object-oriented design and encapsulation should be applied as much as possible. Some teams choose to intentionally create anemic models with little encapsulation, which can lead to problems. Some of my past NimblePros clients have even had coding conventions and standards that basically required every domain entity be essentially a DTO, with no methods and a…

  
  

• Commands, Events, Versions, and Owners

  

  Date Published: 04 May 2022

  Commands and events are two common types of messages used in distributed application architectures, including microservice designs. Sometimes message formats need to be updated.

• Why Use DateTimeOffset

  

  Date Published: 17 January 2022

  Raise your hand if you've stored entity values in a database as DateTime. Ok, everybody has their hand up. You can put your hand down - you look silly doing that while reading an article on some website. Using DateTime for entity properties and database fields is ubiquitous, but if you really care about the time portion of the value, it's often ambiguous. What time zone is the date in? Is it…

  
  

• DateTime as a Value Object

  

  Date Published: 12 January 2022

  Value Objects are a key part of Domain-Driven Design and domain models created by this process. However, they're not used nearly as often by teams as they should be, and they're frequently misunderstood even by experienced dev teams. When teaching teams how to better understand Value Objects and incorporate them more in their domain models, I've found the .NET type to be a useful example. First…

• Make the Implicit Explicit

  

  Date Published: 07 December 2021

  When practicing software architecture and design, one important consideration is how the rules of the system are modeled. Are the rules ad hoc and a matter of tribal knowledge of the developers who came before, or are they explicit in the way the system and its classes are designed and used? Whenever possible, favor making the implicit explicit in your design, so that as developers come and go…

• Avoid Using Exceptions to Determine API Status Codes and Responses

  

  Date Published: 16 November 2021

  It's typical for API endpoints to call application or domain services. In the case of success, the API can simply return Ok and the result of the service call. But for non-success cases, should you use exceptions to communicate from the service to the endpoint, so that it can return an appropriate status code and response? Assuming you read the title of this article, you probably already know the…

• Grouping Assertions in Tests

  

  Date Published: 28 September 2021

  Although it's generally considered a best practice to assert only one thing per test, sometimes one logical "thing" may require multiple assertion statements to be executed. In such cases, it's helpful to be able to see all of the parts of the larger assertion that failed, so you don't end up chasing after them one by one. As an example, let's say you have a class that is initialized with its…

  
  

• GitHub Actions On Demand

  

  Date Published: 27 September 2021

  I use GitHub Actions a lot. They're a great tool for performing continuous integration (CI) and continuous deployment (CD) for your applications. However, by default they typically only are triggered by changes to your application's source code in the form of commits and/or merges/rebases. This means that to trigger a particular workflow, you usually need to make a commit, and obviously this can…

  Date Published: 17 August 2021

  I create a lot of samples, demos, open source projects, etc. and I like to use the fairly standard repository layout of having a solution file in the root and project files in a src subfolder. Achieving this in Visual Studio is tedious, but fortunately this series of dotnet CLI commands quickly create the structure for you. This script uses the following commands, which have good documentation…

  
  

• Writing Efficiently

  

  Date Published: 10 August 2021

  Working in professional software development teams requires a lot of writing. As you advance in your career, frequently the percentage of time you'll be writing emails and other correspondence versus writing source code will increase. As your responsibilities grow, so too does your need to communicate effectively with larger numbers of people in and beyond your organization. Writing effectively is…

  
  

• Improving Method and Function Clarity

  

  Date Published: 22 June 2021

  (Originally sent to my weekly tips subscribers in March of 2019) When you look at a method or function, it should have a name that describes what it does. Naming things is hard but important, and probably the most important thing you can do when you design a method is give it a good name. This mainly applies to methods (or functions) that are or may be called from more than one place. It's less…

  
  

• Prioritizing and Microservices

  

  Date Published: 15 June 2021

  It's not unusual to have different levels of prioritization in backend systems. Imagine you have a process that generates and sends reports that users have requested. Some of these might be low-priority reports that are simply generated periodically so they're available to view, while others might be generated on demand, with a user actively waiting for the results. These could be further…

  
  

• C# Generics Best Practices

  

  Date Published: 08 June 2021

  There was a time when C# didn't support generics. It was a dark time. Ragged bands of .NET developers roamed the harsh landscape, copy-pasting strongly-typed list implementations to avoid the evils of primitive boxing operations. Forced to choose between loose typing and explicit casts at every turn, would-be developers of strongly-typed object models somehow managed to endure and ship (mostly…

  
  

• What If Product Owners Reported to Dev Teams?

  

  Date Published: 01 June 2021

  In most organizations, if there's a Product Owner, the dev team is generally subservient to it and charged with building whatever the Product Owner comes up with. That's not to say they aren't often "on the same team", but the flow of responsibility is usually the PO pushes new requirements and the developers respond to them. Sometimes this relationship, even if only implied, has ramifications for…

• Use AutoHotKey to Paste Text as Typing

  

  Date Published: 18 May 2021

  I've heard about AutoHotKey before but never gotten round to installing it until recently. Basically I had a bunch of text (code) that I wanted to display in chunks as part of an upcoming Pluralsight course. I didn't want it to just all appear at once, but rather to show as if it were being typed. But actually typing frequently involves typos and backspaces and other distractions. I knew others…

  When it's time to build that big new system to replace the aging old one, consider Gall's Law and the benefit of frequent feedback and evolutionary development. Gall's Law states: A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a…

  My blog is hosted on GitHub using GatsbyJS and Netlify. One nice thing about this setup is that I have complete control over my content, and it's all version controlled and backed up both on GitHub and on various machines where I've cloned the repo. Along with the text content, almost all of the images associated with my content are in the same repository. Sometimes they're hi-res screenshots…

  
  

• Testing Exceptions with xUnit and Actions

  

  Date Published: 14 April 2021

  When you're writing unit tests for a method, it's a good idea to test various failure conditions ("sad paths") in addition to testing the expected, everything is working condition ("happy path"). In particular, if you have a method that may throw exceptions, especially if they're custom domain exceptions, you should be sure you're testing this behavior. Another common source of exceptions is guard…

  
  

• Speed Up Docker Compose with Parallel Builds

  

  Date Published: 07 April 2021

  I've been using docker-compose quite a bit lately for a distributed app that includes 3 front end apps, 2 databases, RabbitMQ, and PaperCut (test email server). For the most part, this works great as a way to encapsulate all of these processes and run them in a containerized manner so that everything works together. But building this whole solution is pretty slow, by default. When you work with…

  Date Published: 17 March 2021

  Early in my career I was taught this lesson by one of my clients. We were building an application for internal use at the company which would run on a dedicated server sitting in a server room in the same building as its users. I had concerns that some approach we were taking was inefficient. My client (and mentor at the time) explained: Hardware hides many sins. What he meant was, it didn't…

  Date Published: 03 March 2021

  A recent discussion on the devBetter.com private server spurred this article. One of the members was trying to work out a fairly complex design involving many different parts, and the idea of trying to model all of this as a set of database tables with primary key and foreign key relationships was daunting. The sheer number of many-to-many and one-to-many relationships along with recursive and…

  
  

• What is the difference between a DTO and a POCO (or POJO)

  

  Date Published: 16 February 2021

  Two terms that come up frequently when discussing software development in .NET and C# are DTO and POCO. Some developers use these terms interchangeably. So, what is the difference between a DTO and a POCO? First, let's define each term. Data Transfer Object (DTO) A DTO is a "Data Transfer Object". It's an object whose purpose is to transfer data. By definition, a DTO should only contain data, not…

• Data Deficient Messages

  

  Date Published: 16 December 2020

  A common feature of distributed architectures is message-based communication between systems or microservices. Whether using a message bus or queue, messages provide a means of reducing coupling between systems, allowing overall systems to remain available even when some subsystems are not. However, when designing the messages that will be used in such systems, care must be taken to include…

  
  

• Avoid Wrapping DbContext in Using (and other gotchas)

  

  Date Published: 01 December 2020

  EF and EF Core DbContext types implement . As such, best practice programming suggests that you should wrap them in a block (or new C# 8 using statement). Unfortunately, doing this, at least in web apps, is generally a bad idea. I work with a lot of clients who are migrating from .NET Framework to .NET Core and .NET 5. Some of them weren't using dependency injection in their legacy apps, or weren…

• CAP Theorem, PACELC, and Microservices

  

  Date Published: 17 November 2020

  CAP Theorem (wikipedia) is a classic "given 3 choices, choose 2" topic. The three choices are Consistency, Availability, and Partition Tolerance. You can't have all three. CAP Theorem Given distributed data or systems, the choice mostly comes up when there is a network partition, meaning two nodes of the system can't communicate immediately with one another. At that point there is a partition, and…

  Date Published: 03 November 2020

  This is the fifth and last of the 5 Laws of Software Estimates. I expanded on the fourth law of software estimates in my previous article. Like all things, how you view estimates is heavily context-dependent. If you're a developer who wants to maximize the amount of value you provide by building software, estimates do little to support this directly. As already covered by the previous 4 laws of…

  Date Published: 14 October 2020

  This is the fourth of the 5 Laws of Software Estimates. I expanded on the third law of software estimates in my previous article. Estimates are made for a given point in time, when a certain set of information and assumptions are known and held. As time passes, new information becomes available and assumptions change. The older the estimate, the more likely it is to be stale. Since by definition…

  
  

• Estimates Are Wrong

  

  Date Published: 07 October 2020

  This is the third of the 5 Laws of Software Estimates. I expanded on the second law of software estimates in my previous article. Nobody should be surprised when estimates are wrong, they should be surprised when they are right! If estimates were accurate, they'd be called exactimates. Think about weather forecasting. Even with all of the software modeling and vast arrays of sensors we have in the…

  
  

• Estimates Are Non-Transferable

  

  Date Published: 23 September 2020

  This is the second of the 5 Laws of Software Estimates. I expanded on the first law of software estimates in my previous article. Estimates generally cannot be transferred between individuals. If I ask five team members to estimate a given story, using whatever units they wish (time, points, etc.), I'm likely to get a range of answers that could vary by 200% or more! The hope may be that averaging…

  
  

• Estimates Are Waste

  

  Date Published: 16 September 2020

  This is the first of the 5 Laws of Software Estimates. It's all about context. In the context of software development, of delivering business value in the form of working software, estimates provide no value. In the context of choosing what software to build, there may certainly be value in estimates, but even there it's an ROI calculation, with the hope being that the estimates will provide more…

Nonetheless, they're important and ideally they should run as part of your build pipeline. Recently I've come up with a technique that works quite…

  
  

• Configure Different Implementations for Different Controllers in ConfigureServices

  

  Date Published: 09 October 2019

  You may find yourself in a position where you need to have two (or more) different implementations of the same interface within your ASP.NET Core application. This may be because your application is too big to allow you to fully replace one implementation with another all at once, so you're rolling out the updates one type at a time. Let's say the services in question relate to persistence, and…

• Attacking Technical Debt

  

  Date Published: 18 September 2019

  Technical Debt is a metaphor for shortcuts and hacks in software that make it more difficult to change and maintain than it could be with an optimal design. Many applications have accumulated a large amount of technical debt, and figuring out how to deal with it is a fairly common challenge for many developers, especially senior developers starting new contracts or jobs at companies that need help…

  
  

• Enforce Developer Workflow Policies with Branch Protection

  

  Date Published: 11 September 2019

  Last updated: 13 October 2023 A frequent question I hear from clients is some variant of "Ok, Continuous Integration is great, but how do we get everybody on the team to pay attention to it?" This is obviously a bigger problem if the question is coming from a lone junior developer, as opposed to a technical manager. In the case of the junior developer, they may need some help convincing the rest…

• Configure Visual Studio to Name Private Fields with Underscore

  

  Date Published: 20 August 2019

  Last updated: 13 October 2023 Most C# coding standards recommend using camelCase for local variables and _camelCase for private or internal (and I also say for protected, but that's just me) fields. Unfortunately, out of the box Visual Studio just uses camelCase for these fields, which makes typical dependency injection scenarios annoying in constructors: I much prefer this version: Fortunately…

  
  

• Using Multiple Solutions in Visual Studio

  

  Date Published: 14 August 2019

  I've given this advice quite a number of times so I figured it was time to put it into an online article. If you're a .NET developer you probably use or have used Visual Studio. Visual Studio has two kinds of project organization file formats: projects and solutions. Solutions are essentially groups of projects. Most software applications involve more than one project, and so virtually every…

  
  

• Minimize new in Automated Tests

  

  Date Published: 07 August 2019

  Last updated: 13 October 2023 Automated tests have gained a lot of acceptance in recent years. Not long ago, many organizations bristled at the notion of having their expensive developers spend time writing code that wasn't actually going to ship to production, but instead would just verify that the "real" code worked. Today, the idea that testing in many instances is something computers can do…

  
  

• How to Grab a Pull Request Locally with Git Command Line

  

  Date Published: 29 July 2019

  If you're working with git, especially with open source, sometimes you'll find that you want to work with a particular pull request, or PR, locally. Maybe you're reviewing the PR and instead of just eyeballing it in the browser you want to actually run the code and see what it does (novel idea, I know!). In any case, actually getting the code from a PR, especially one from a fork that isn't even…

• Set up Reverse DNS (PTR) Record for Windows Azure

  

  Date Published: 14 April 2019

  Windows Azure offers support for RDNS (PTR) records, which are used to get a hostname from an IP address (the opposite of what DNS does, hence the name). Microsoft has an article that describes how to set RDNS up, but it assumes you've already installed the azure CLI tools. Since I'm going through the process from scratch, I thought I'd share the full process here. You'll need to have npm…

  
  

• Add HTTPS To Any Site For Free

  

  Date Published: 06 March 2019

  Back in the old days, adding HTTPS/SSL/TLS to secure a web site was a big deal. You had to spend hundreds of dollars for a certificate, then install it on the web server. It had to be specific to the subdomain you were using, or you had to shell out even more bucks for the wildcard cert. And they’d expire sometimes, and your site would go down, and that was never fun. Times have changed. Yes, you…

  When looking at tuning application performance, a common principle to follow is this one: Maximize the amount of work not done. It's hard to make doing something faster than doing nothing, so do nothing whenever you can. A common way to do very little is to queue up work (in the form of a Command, typically) so that some other process can actually perform the work later. However, you can also…

Ok, so in that example, I had a list of options (for instance, Roles) that I wanted to represent using objects instead of primitive enum…

  
  

• Keep master and origin branches working if possible

  

  Date Published: 22 November 2017

  Here are two tips that teams I work with have found useful when working with git for larger projects with many team members that I thought I would share: Only merge into master if code is working The first tip is that you should only merge (or commit, but that should be rare) into master if your code is working. That is, it compiles and all of its tests run, and not just on your own machine, but…

  
  

• Displaying and Setting Current ASP.NET Assembly Version

  

  Date Published: 15 November 2017

  When you’re building web applications and you’re setting up continuous integration and delivery pipelines, it’s worthwhile to know which particular version of the application is deployed to a given environment. One of the easiest ways to share this information is from the application itself. Many sites will display build or version information in their footer or on a particular page. You can do…

  
  

• Razor Pages Model NullReferenceException

  

  Date Published: 14 November 2017

  Here’s a quick tip: If you’re adding a new Razor Page to an ASP.NET Core 2.0+ project, and you add a codebehind model class, but then when you try to use it you get a NullReferenceException, this might be why. First, specify the model correctly from the razor page (Index.cshtml): If you’re literally adding just one page to your project, you need to make sure you specify the full namespace of the…

  
  

• Enforcing Model Validation Policy in Web APIs

  

  Date Published: 09 November 2017

  If you’re exposing a Web API, one of the most basic things you should be doing on every request, and especially on those requests that mutate your system’s state, is ensuring that the data you’re accepting is valid. ASP.NET Core MVC (and Web API 2 and MVC 5, too!) supports model validation as part of the model binding process. You’re likely familiar with it and have seen it used in combination…

  
  

• Encapsulation in Objects and Applications

  

  Date Published: 01 November 2017

  Encapsulation is a key principle of software development in general, and object-oriented design in particular. It refers to the ability for constructs (objects, functions, other things) to expose a public interface with which clients can interact, while keeping their internal implementation hidden. Encapsulation offers a host of benefits, most important being to allow the construct in question to…

• ASPNET Core InMemoryDatabase Upgrade Breaking Change

  

  Date Published: 05 October 2017

  There’s a minor breaking change in ASP.NET Core 2.0 that I’ve encountered while updating my Clean Architecture sample. In 1.x, you could configure EF Core to use an In Memory database, and when you did so, you could optionally specify a name: One of the most common scenarios for using an in memory database is for testing. Unfortunately, the state of the in memory database is not reset between test…

  
  

• Your API and View Models Should Not Reference Domain Models

  

  Date Published: 03 October 2017

  If you’re organizing your application following Clean Architecture and Domain-Driven Design, with your Core domain model in one project that is referenced by your UI and Infrastructure projects, you should be careful what you expose in your client-facing models. Client facing models typically reside in the UI layer as ViewModels or ApiModels, or they may be called DTOs (Data Transfer Objects). In…

  
  

• Better Performance from Async Operations

  

  Date Published: 25 September 2017

  The C# language has had support for the async and await keywords (and yet another new way to perform asynchronous operations) for a while now. They’re still confusing to many developers (including me sometimes!) and can be a source of many pitfalls. I mostly work in ASP.NET projects, and the default project templates have all been using async for some time. New developers often assume this is…

• ASPNET Core Razor Pages – Worth Checking Out?

  

  Date Published: 31 August 2017

  You may have heard that in ASP.NET Core MVC 2.0, there is a new feature called Razor Pages. This feature allows you to create pages that don’t need to have a controller or action, and which can optionally have an associated PageModel class instead of a ViewModel. If you’ve been programming for a while, especially in the ASP.NET space, this may trigger some immediate reactions. Oh no! The return of…

• Breakpoint Labels in Visual Studio

  

  Date Published: 29 August 2017

  Breakpoints offer a great way to debug our software, letting us literally stop time during code execution and inspect what's going on at that moment. It's a bit like being a speedster like Quicksilver, who can almost stop time and manipulate the environment between moments in time: Unfortunately, in larger applications, we may find that we have quite a few places where we might want to stop and…

  
  

• Troubleshooting Razor Pages and PageModel Classes

  

  Date Published: 27 August 2017

  When using the new Razor Pages feature in ASP.NET Core 2.0, you can (and usually should) define a separate “codebehind” file for your PageModel class. If you’re using Visual Studio, this class will be associated with your Razor Page as a nested file in the Solution Explorer, making it easy to locate. The class will also be easier to unit test than if you were to put your functionality directly…

  
  

• Debugging ASPNET Core Routes

  

  Date Published: 23 August 2017

  Routing in ASP.NET MVC apps has often presented challenges to developers, resulting in a bunch of different route debugging tools and nuget packages. In ASP.NET Core, there tends to be less routing confusion because of the emphasis on attribute routing, rather than the traditional routing tables. With ASP.NET Core 2.0 and Razor Pages, this trend continues since Razor Pages use convention-based…

• Logging and Monitoring are Requirements

  

  Date Published: 08 August 2017

  It’s common in many applications to see logging and monitoring added into the code as an afterthought. It’s rarely included in the specification for a feature or product, and it’s rarely tested. Thus, it’s often inconsistently implemented. One approach to addressing this is to use techniques like AOP to broadly and consistently add logging via rules. However, this often falls short and doesn’t…

  Date Published: 08 August 2017

  When it’s important, logging should be considered a “real” requirement, not just a developer or operations afterthought. In many cases, especially diagnosis of production problems, logging has real business value. Thus, there are times when you’ll want to test that your logging works. Consider the following function: Let’s assume for a moment that when this exception occurs, it’s potentially…

  If you’re using the dotnet CLI tools to develop your .NET Core apps, you’re probably very familiar with typing dotnet run and/or dotnet test every time you make a change to your app. This kind of manual process, even if you’re a quick typist (or just use up-arrow, enter), can add friction to your process. Friction is bad, and can bring you out of the zone when you’re trying to focus on improving…

• How to remove untracked local files from git working tree?

  

  Date Published: 31 May 2017

  There are two ways to get rid of untracked files from your git working tree. The first one, which many of us have done, is to simply go to a new folder (or delete the current one) and perform a fresh git clone operation. This “burn it to the ground and start from scratch” approach works, but there is a more elegant solution: git clean. To use git clean, it’s a good idea to first run it with the -n…

  Command line tools are becoming increasingly popular, so this tip may save you some time. On Windows, there are several ways to open up a command window. My typical method is to just hit the Start key and type 'cmd' and then enter. This will open a window in my user folder, which is exactly where I want to be precisely 0% of the time. From there, it's usually just a few dozen commands to change…

  
  

• UseStatusCodePages Middleware Problem Resolved

  

  Date Published: 01 December 2016

  If you’re trying to get the ASP.NET Core Status Code Pages middleware to work, but it just is ignored no matter what, one thing to check is the rest of your middleware pipeline. If you have middleware that is writing anything to the response, it will cause the status code pages middleware to be ignored. For example, the following middleware: I had this set up in front of some other middleware to…

• Avoid Storing Database Credentials in Source Control

  

  Date Published: 19 October 2016

  Your application probably needs to communicate with a database of some kind. Naturally, that database isn’t open to the world – it needs to be protected and secured. The typical solution to this is to create a username and password combination (ideally, specific to each application or user that requires access) and configure the application with these credentials. In many cases, they’re simply…

So I checked my GitHub profile page, figuring it would show things that recently mentioned me. Unfortunately, not. I posted to twitter…

  
  

• Configuring ASPNET Core Apps with WebHostBuilder

  

  Date Published: 09 September 2016

  In ASP.NET Core apps, you typically configure the application in Startup. However, the application itself runs inside of a host, which is configured separately using a WebHostBuilder. Although it’s not the default, recommended case (and thus isn’t shown in the official docs), you can actually configure the application directly from WebHostBuilder and avoid using a Startup class entirely (or…

  
  

• Specifying API Routes in ASPNET Core

  

  Date Published: 08 September 2016

  ASP.NET Core uses attribute routing to determine the behavior of web APIs. Its integrated support for MVC and Web API is one of my favorite features, since working with MVC 5 and Web API 2 was painful due to the similarities but separate implementations of the two stacks. When creating routes for your APIs, a common approach is to use something like this: When applied to a particular API…

• Refactoring Static File System Access

  

  Date Published: 16 August 2016

  Years ago, I was trying to test an application I’d written, but couldn’t figure out how to remove a dependency it had on the file system. At the time, I was familiar with unit testing, and had bought into its value both as a developer and as a business owner (this was software that was central to my business at that time), but I was stymied by some code that looked something like this: `public…

  
  

• Refactoring Static System Clock Access

  

  Date Published: 10 August 2016

  If you have logic that depends on dates and/or times, it can be difficult to test if it’s directly accessing the system clock (via DateTime.Now in .NET, for example). This is an example of an insidious dependency that can add unnecessary coupling to an application, making it harder to maintain. Fortunately, it’s pretty easy to refactor your code to address this issue. First, realize that you don’t…

  
  

• Real World ASPNET Core MVC Filters

  

  Date Published: 08 August 2016

  Filters are a great, often underutilized feature of ASP.NET MVC and ASP.NET Core MVC. They provide a way to hook into the MVC action invocation pipeline, which makes them ideal for pulling common repetitive tasks out of your actions. Often, an app will have a standard policy that it applies to how it handles certain conditions, especially those that might generate particular HTTP status codes. Or…

  
  

• Persisting the Type Safe Enum Pattern with EF 6

  

  Date Published: 04 August 2016

  I’ve written about Enum Alternatives in C#, and a common problem developers encounter when they try to use such an approach is persistence.

However, you can add support to let EF map these types to database columns as you would expect without too much effort. Here’s a quick example you can try yourself with…

  
  

• Refactoring Static Config Access

  

  Date Published: 03 August 2016

  A common but insidious dependency in many .NET applications is their use of configuration, including appSettings. The main issue is static access to config for values that affect the behavior of the application (values that are simply displayed, or used for things like email servers or addresses, aren’t usually an issue). Imagine you have some code like this: Imagine this method is used to gather…

  Date Published: 30 June 2016

  Recently I was mentoring a client who needed a simple filter for a table of data. In this case, they weren’t using a viewmodel-based framework, so it wasn’t an option to simply modify the collection to which the table was bound. We needed to use old school jQuery.

• Finding Copies of Images Online

  

  Date Published: 10 September 2014

  Obviously it’s very easy to download and reuse images on the Internet. However, if your business depends on such intellectual property, you may need to take steps to prevent unauthorized usage of your images. There are many ways you can mark your images to later prove they are yours – that’s a topic for another day – but you may not know there is also a very easy way to find other images and where…

  
  

• Logging in Entity Framework

  

  Date Published: 15 August 2014

  When working with any ORM tool, it can sometimes be helpful to see just what, exactly, is being sent to the underlying data store. This can help identify bugs as well as performance issues in how the query is being performed (or how many queries are being performed, in the case of SELECT N+1 problems). There are several existing tools available that provide assistance with this: SQL Server…

  
  

• RGRC is the new Red Green Refactor for Test First Development

  

  Date Published: 05 August 2014

  Test Driven Development (TDD), aka Test Driven Design, aka Test First Development, has long had a simple, virtuous cycle at the heart of its workflow: Write a failing test (run the test(s) – they should be RED) Make it pass in the simplest way possible (tests are GREEN) Now clean up the code (eliminate duplication and other code smells) (REFACTOR) When following this workflow, one can make steady…

  My preferred IoC container is StructureMap, but I’m going to be working with a client who uses Castle Windsor as their standard container, so I decided to learn a bit about it this week. I created a simple console application and included some interfaces and implementations to see how things work. Registering individual interfaces and wiring them up to their implementations is pretty…

  The other night at the Hudson Software Craftsmanship meeting at the Falafel Software training center in Hudson, Ohio, I did the Red Pencil Kata using JavaScript. Although I’ve run into it in the past, I was stuck for a little while (I was the odd man out without a pairing partner to help find these things faster) due to one of JavaScript’s “fun” date conventions. Being a C# developer primarily…

  
  

• Where to Declare Variables in C# and JavaScript

  

  Date Published: 16 July 2014

  Both JavaScript and C# belong to the C family of languages. They share curly braces and semi-colons, and in fact there are many cases where the exact same code will execute (correctly, in most cases) as either language. However, there are certain best practices that are unique to each language, and where variables should be declared is one of them. Declaring Variables in C# In C#, it’s generally…

  
  

• Ensure You Are Not Adding To Global Scope in JavaScript

  

  Date Published: 15 July 2014

  A key best practice if you’re writing JavaScript code is to avoid adding objects to the global scope. There are several good reasons for this – globals add coupling, it makes it easier for disparate libraries to break one another, etc. A general rule of programming is to avoid global scope, in fact. Unfortunately, JavaScript makes adding things to global scope very easy. Consider this bit ofcode…

  
  

• Resolving Dependencies in ASP.NET MVC 5 with StructureMap

  

  Date Published: 25 June 2014

  In a previous post I showed how to use StructureMap with ASP.NET MVC 3. It’s been a couple of years, so I figured it was time to update that article with the steps for getting StructureMap working in ASP.NET MVC 5.

  Update: If you want to use StructureMap with ASP.NET MVC 5, I have a walkthrough on this now as well. As I write this, the best resource for official documentation on ASP.NET MVC 3 is of course MSDN. You can also learn more about ASP.NET MVC 3 here. However, neither of those mention how to properly set up an IOC Container (like StructureMap) with ASP.NET MVC 3. After some searching, I was able to…

  
  

• Rename Elements in PowerPoint

  

  Date Published: 14 June 2014

  In PowerPoint, especially if you’re working with a complex slide with a lot of animations, it can be difficult to easily determine which named element corresponds with which visual element on the slide. By default, when you add pictures and other assets to a slide, they get names like ‘Picture 5’. It would be great if there were an easy way to rename these elements, especially from the Animation…

  
  

• Tip – Override ToString() in Objects

  

  Date Published: 12 June 2014

  Most of your domain objects should override ToString() for the simple reason that if you ever want to simply display the object’s state, you shouldn’t need to implement a custom formatter for it. Furthermore, it’s well-known that the default System.Object implementation of .ToString(), which outputs the type’s name, is useless 99% of the time. Thus, it’s generally a good idea to implement…

  I recently moved the DevMavens.com site from one server to another and needed to ensure that the www.devmavens.com domain correctly redirected to simply devmavens.com. This is important for SEO reasons (you don’t want multiple domains to refer to the same content) and it’s generally better to use the shorter URL (www is so 20th century) rather than wasting 4 characters for zero gain.

  I’m watching the Introduction to Kendo UI course by Keith Burnell on Pluralsight and decided to play around a little bit with templates, which are a pretty powerful feature. If you’re a server-side web developers, templates should seem pretty familiar to you. Any ASP or ASP.NET page can be thought of like a template, in which you mix markup and dynamic data expressions. In this case, the templates…

You could code it like this: Now, if you want to start passing in parameters, you can easily do so by parameterizing the method, but…

  
  

• When Should You Refactor

  

  Date Published: 03 January 2014

  A common question teams face is, when should we take the time to refactor our code? Refactoring is defined as improving the design or quality of code, without changing its external functionality. Most teams face constant pressure to release features and/or fix bugs as quickly as possible, so it’s not uncommon for problems discovered in the codebase to be put on the back burner to be fixed “later…

  Date Published: 21 May 2013

  A while ago I ran a poll on twitter asking how developers recommend regions be used. About 15% of the respondents chose Other and/or chose to leave a comment. The comments are useful because they often highlight answer categories that I overlooked when I set up the poll. In this case, there were a lot of comments, I think because there are a lot of different opinions about regions in general, some…

  
  

• When To Comment Your Code

  

  Date Published: 09 May 2013

  My opinions on comments in software code have evolved with my experience. When I was a teenager first learning to program for real, I rarely used comments unless the code was for an assignment, in which case it was a forced exercise every bit as much as teachers’ requests to “show your work” added verbosity to my math and science problems’ solutions. Of course, the programs themselves were quite…

• Limit SQL Server Memory Use on Dev Machine

  

  Date Published: 06 November 2012

  If you’re a developer running SQL Server locally, you may sometimes need to limit how much memory the database is consuming. Under normal conditions, SQL Server likes to use as much memory as it can get, since keeping results in memory improves the database’s performance. In typical production scenarios, this is the ideal behavior, but on a dev machine you probably want your RAM for other things…

• Asus Zen Ultrabook Revisited

  

  Date Published: 27 March 2012

  A couple of months ago I got an Asus Zen ultrabook, which I posted about when I first got it, and a month or so later. Now that I’ve had it a while, I thought I’d post one more time with how it’s continued to work for me. I’m still very happy with its look, feel, and speed. It’s very responsive both while up and running and when waking up or shutting down. One thing I wish it came with is an HDMI…

  
  

• How Do I Disable Zoom in an iPad iPhone Mobile Web App?

  

  Date Published: 26 March 2012

  If you’re building web-based applications for mobile devices like the iPad/iPhone and you want to mimic native applications’ look and feel and experience, one thing you may want to do is disable the pinch zoom gesture. Most native applications don’t offer support for this, but of course most mobile browsers currently do, so a sure way for users to tell that they’re actually viewing a web page is…

  Not long ago, while preparing my Kanban Fundamentals video training class for Pluralsight, I read Personal Kanban, by Jim Benson and Tonianne DeMaria Barry. If you’re new to the concept of kanban, this book is a good place to get started (along with my course, which is about 90 minutes long, and shorter if you speed it up). I read the kindle edition of Personal Kanban, even though I don’t own a…

• Sending Email from a Sitefinity Module with Attachments

  

  Date Published: 24 February 2012

  A fairly common use case in web applications is the need to send an email, and applications built on top of Telerik Sitefinity are no different. Since modules are simply .NET DLLs, you’re free to write whatever code you like, so it’s certainly possible for you to write a module that sends emails in a way that knows nothing about Sitefinity. However, if you want to interact with Sitefinity, for…

  Date Published: 09 February 2012

  In working on a client’s reporting system, I ran across some StackedBar charts that were using the System.Web.DataVisualization.Chart control that were having some problems. The biggest one was that the rendered bars had gaps and floating rectangles in it.

• Unit Test or Integration Test and Why You Should Care

  

  Date Published: 19 January 2012

  There remains a fair bit of confusion about what constitutes which kind of test. Many developers are fairly new to testing, and tend to call any tests of their code “unit tests” even when they’re dealing with something substantially larger than a unit. The tools don’t really help much here, since the various test runner frameworks all call themselves unit test frameworks, and the various test…

  Date Published: 19 January 2012

  If you’re at all serious about testing, at some point you’re going to have a rather large suite of tests that need to run, and you’ll find that your builds are taking longer than you would like because of how long the tests run. For example, consider this suite of 24 tests, each one of which looks like this one: If you run 24 of these, it’s going to take about 24 seconds, by default: Now of…

• Inner Fields and Lazy Initialization in C#

  

  Date Published: 29 October 2011

  Using lazy initialization in C#, a class’s state is set up such that each property’s get method performs a check to see if the underlying field is null. If it is, then it calculates or populates the field before returning it. This is a very simple and common approach, but it requires that the class follows a convention of only accessing the field via the property. Unfortunately, there are no…

  I wrote a couple of weeks ago about using Visual Studio 2010’s Performance and Load Testing tools to analyze and correct some performance concerns with the Stir Trek Conference web site (which, by the way, is 2 weeks from today!). I realized, though, that there are a bunch of mobile applications that are set up to use the site’s XML and JSON data feeds, and I hadn’t measured or tuned these at all…

  
  

• Configuring a WCF Service to Run Via HTTPS

  

  Date Published: 22 April 2011

  Yesterday I wrote about how to wire up jQuery UI’s AutoComplete add-in to a WCF Service to create an autocomplete search/navigation control. Today I deployed the resulting code to production but initially had some trouble getting things to work. The only real difference between the two environments is that in production everything goes through HTTPS/SSL, so I figured that had to be the culprit. A…

  
  

• Creating an Autocomplete Redirect Navigation Control using jQuery UI

  

  Date Published: 21 April 2011

  On an application I’m working on, there’s was an ASP.NET DropDownList used for jumping to a particular account. This, when enhanced with the AJAX Control Toolkit’s ListSearchExtender, provided an awesome user experience for quickly navigating to a particular account. Just click the control, and either scroll, or better, type in the first few characters of the name of the account, and it was…

  
  

• Creating a Simple ASP.NET Report with Export to Excel

  

  Date Published: 19 April 2011

  Introduction One of my very first articles was on exporting reports to Excel using Active Server Pages, and this article still gets over a thousand views per month. Today I had to create a quick report for internal use and I thought it would be helpful for the user to be able to quickly export the results to Excel. Thus I found myself, over a decade later, going through much the same process as…

• How To Fix Visual Studio File Templates

  

  Date Published: 25 March 2011

  When you create a new project in Visual Studio, it will usually include some files as part of the project. Most of the time, these are pretty useless, but if it’s your first time working with said template, they may help you get going. In VS2010, the Test Project, for example, has been improved over prior versions by eliminating a useless text file describing tests and a useless Manual Test file…

  Date Published: 22 February 2011

  Introduction Sometimes your domain objects have one-to-many or many-to-many relationships with other objects. For instance, your Customers might have collections of Orders associated with them. The simplest way to model this is to expose a field or property off of your Customer class. Unfortunately, this has a number of negative consequences because of how it breaks encapsulation. Fortunately…

  Date Published: 16 February 2011

  If you ask a newly-hired developer this question while they are busy coding away on something, you’ll usually get an answer like “the Acme project.” If that’s too obvious (after all, maybe that’s the only project this dev works on), then the answer might be “the new xyz feature” or “that abc bug.” All of these are more-or-less valid responses, and depending on the scope of the response, they might…

  
  

• Building a CachedRepository via Strategy Pattern

  

  Date Published: 15 February 2011

  In part one of this series, I introduced the CachedRepository pattern, and demonstrated how it can be applied through the use of simple inheritance to an existing Repository class.

  This wraps up my mini-series on using PowerShell to help manage services running on multiple remote servers. In my case, these scripts exist to make it easy for me to globally start and stop services on a number of web servers that are part of Lake Quincy Media’s AdSignia ad platform – you can read more about the message-based architecture we’re using here. I learned the basics of starting and…

  
  

• Pass Results from One PowerShell Script To Another

  

  Date Published: 06 February 2011

  If you’re using PowerShell but want to keep your scripts DRY, you may want to factor common functions into their own scripts, and then call these scripts from multiple other scripts. This is pretty easy to do. For instance, if you have an array of values that you want to use as inputs for several scripts, you could create a file like this one: Colors.ps1 Now, to use this in another PowerShell…

  
  

• Message-Based Architecture Goodness

  

  Date Published: 06 February 2011

  Recently at Lake Quincy Media we upgraded our logging system for the AdSignia ad platform so that it uses messaging rather than direct SQL database access. This allows us to log much more detailed data, which we can then analyze, and also improves the performance of every ad request, since it eliminates a database call and replaces it with a local queue operation, which is much faster and less…

  Date Published: 10 January 2011

  I’ve been writing tests and unit tests for quite a while, and naturally my personal preference for naming them has evolved somewhat with time.

  Date Published: 24 August 2010

  I just ran into an odd issue with a VS2010 project. In my case it was an MVC 2 application I was upgrading from VS2008. One of the built-in controllers (ProfileController) was failing to compile because it could not resolve the Linq extension method symbols Single() and Matches(). These are located in the System.Core assembly. I checked my project references in Solution Explorer, and System.Core…

  
  

• Using CCTray with JetBrains TeamCity

  

  Date Published: 23 August 2010

  TeamCity is a great build server tool from JetBrains (makers of the awesome Visual Studio add-in, ReSharper). The user-interface and features of the TeamCity web front-end are wonderful and are leaps and bounds easier to use for new users than my previous favorite, CruiseControl.Net, which required much XMLness to configure. However, one of my favorite tools from CruiseControl, CCTray, still has…

  
  

• Code Analysis Techniques

  

  Date Published: 17 August 2010

  There are a number of code analysis tools available for .NET developers, including some stats that are built into the pricier SKUs of Visual Studio. Recently, I’ve been playing with a relatively new product (released earlier this year by Microsoft agile consulting shop NimblePros.com) called Nitriq. Nitriq is a bit like LINQPad for your code. If you’re not familiar with it, go download LINQPad now…

  Date Published: 07 July 2010

  There a new feature of IIS called Application Pool Identities that was apparently introduced with SP2 of Windows Server 2008. There's a nice overview of Application Pool Identities here, which is the basis for this post, which is just my notes on the feature.

• Set Up Build Agents By Project in TeamCity

  

  Date Published: 06 July 2010

  We’re using TeamCity to manage our continous integration builds for CodeProject.com and LakeQuincy.com. Before TeamCity, I was using CruiseControl.net, and TeamCity is much easier to get working (and requires far less XML manipulation). I do miss CCTray, which I found to be much nicer than the TeamCity tray notifier (which if you click on it never shows anything immediately – it has to go and get…

  
  

• How Can I Determine The Current Controller or Action in an Html Helper

  

  Date Published: 02 July 2010

  If you’re writing an HTML Helper for ASP.NET MVC you may want to do something different based on whether the page that is to be rendered was arrived at via a particular controller or controller action. I found the following code which does just this in one of the ASP.NET MVC Themes available from the www.asp.net web site (the Dark theme, I believe it’s called). Note that I’ve already modified this…

  
  

• Tagging Releases in Source Control

  

  Date Published: 22 June 2010

  A best practice when you're using source control is to tag your releases. What does this mean, exactly? If you're following the relatively standard non-distributed source control repository folder structure of having root folders for: branches tags trunk then it means simply making a copy of the current state of the system when you did your release. Here's how to do it using Subversion (SVN) and…

  
  

• Great Uses of Using Statement in C#

  

  Date Published: 18 June 2010

  In my last post about testing emails in .NET, I noted the use of the using statement to ensure safe usage of the IDisposable SmtpClient and MailMessage objects. This is the typical usage of the using statement, but you can take advantage of this statement’s behavior for other scenarios as well, resulting in cleaner code. Consider the scenario where you want to perform some kind of pre- and post…

  
  

• Moving a Certificate Between Web Servers

  

  Date Published: 18 June 2010

  I'm in the process of moving Lake Quincy Media's web site from one server to another, and since it uses SSL to secure users' data, I had to move the certificate to the new server as part of the server move. Fortunately, this process is quite painless. First, you need to export the certificate to a .pfx file and give it a password, using these steps: Start, Run, MMC (I did it as administrator) Go…

  
  

• Testing Email Sending

  

  Date Published: 17 June 2010

  Recently I learned a couple of interesting things related to sending emails. One doesn't relate to .NET at all, so if you're a developer and you want to easily be able to test whether or not emails are working correctly in your application without actually sending them and/or installing a real SMTP server on your machine, pay attention. You can grab the smtp4dev application from codeplex, which…

  In your code, you’ll sometimes have write code that validates input using a variety of checks. Assuming you haven’t embraced AOP and done everything with attributes, it’s likely that your defensive coding is going to look something like this: Do you see a problem here? Here’s the deal – Exceptions should be meaningful. They have value at a number of levels: In the code, throwing an exception lets…

• Adding Attributes to Generated Classes

  

  Date Published: 16 April 2010

  ASP.NET MVC 2 adds support for data annotations, implemented via attributes on your model classes. Depending on your design, you may be using an OR/M tool like Entity Framework or LINQ-to-SQL to generate your entity classes, and you may further be using these entities directly as your Model. This is fairly common, and alleviates the need to do mapping between POCO domain objects and such entities…

  
  

• Fix: Cant Change or Remove Visual Studio 2008 from DVD

  

  Date Published: 08 March 2010

  If you installed Visual Studio 2008 on a 64-bit operating system, you may have trouble when you try ad add or remove functionality by inserting the disk (or remounting the ISO image). I believe this is because of the path used to install the 32-bit Visual Studio program.

  Yesterday I was looking at some old code and refactoring it to clean it up (in this case I wasn’t the original author, but I’ve written code just like this). The application in question was a simple process that had to run once per month, on demand, and so was coded up as an EXE application. As it ran, it provided updates on its progress, so it looked something like this: In reviewing this simple…

  
  

• SELECT from a Stored Procedure

  

  Date Published: 24 February 2010

  Occasionally I find myself wanting to SELECT from a SPROC in SQL Server. Usually this is because I want to ORDER the results or filter them further with a WHERE clause. Unfortunately, you can’t just do this: There are several workarounds here, and the appropriate one depends mostly on whether you have any control over the use of the stored procedure, or how it works. For example, you could choose…

  
  

• Avoid Regions for Interfaces in Visual Studio

  Building software applications is sometimes compared with building structures out of smaller components. The children's toys, Legos (and their generic brethren), come to mind and in fact make for a good analogy. Given a set of components with varying characteristics (shape, color, etc, or in the case of software, objects with different behavior and state), it is possible to connect the components…

  A couple of days ago I was annoyed that Resharper was insisting on turning my abstract base NUnit test class with nothing in it but a shared [SetUp] method into a one line class with a collapsed Setup / Teardown region in it. While I didn't always feel this way, my experience has taught me that regions are a smell in your code. They are a way to hide things you don't want to deal with or look at…

  Date Published: 19 December 2009

  If you’re doing any work with WCF (and perhaps Silverlight, for example, but any client will do) and you’d like to maximize the performance of your messages, you’re probably using binary encoding as it’s much less verbose than other options.

In our case, we are testing to see if the browser has Flash installed, and save the result in a cookie since it is a relatively expensive operation and we do not want to have to repeat it…

  
  

• Client Side Client Detection

  

  Date Published: 10 September 2008

  I just heard about a new flavor of the top of the line client detection component, BrowserHawk, that is being branded as “BrowserHawk To-Go (BHTG).” What’s interesting about this (to me) is that it’s following a SaaS model and a pay-as-you-go scheme for pricing. This makes the software very affordable for startup sites and simplifies the installation requirements. Implementation in this case is…

• Client Cache Headers

  

  Date Published: 08 August 2008

  Anybody who’s talked to me about web programming in the last 5 years or so knows that I’m a big fan of caching. However, in most of my presentations on ASP.NET caching, I don’t get into the client side of things. Mainly this is because ASP.NET is a server-side technology and there’s plenty of cool stuff to talk about on the server with regard to caching, and I truly think that’s where the biggest…

• Avoid app Settings Usage in Controls or Shared Libraries

  

  Date Published: 28 July 2008

  Since .NET 1.0, there has been a built-in appSettings section in configuration files. Many developers use this space to store application settings, such as the name of the site or (before ) database connection information. However, many third party tools also make use of this collection, which is a bad practice. Third party tools should use their own configuration section, which is incredibly easy…

  Date Published: 28 July 2008

  I’ve been meaning to set up batched loading of the JavaScript libraries used by Lake Quincy Media’s administration application for some time, and finally had a chance this past weekend. The site uses a variety of third-party tools such as DevExpress,ComponentArt,AJAX Control Toolkit,Overlib,PeterBlum,Dundas Charts, and probably a couple of others I’m forgetting at the moment.

  Oren has a post showing how he deals with time sensitive code in his unit tests. One thing that’s interesting is that, like my previous post, deals with the System.Func construct introduced in .NET 3.5. I see this convention more and more and it’s really growing on me.

• ASP.NET AJAX Download Performance Improvement Request

  

  Date Published: 15 April 2008

  I’m a big fan of ASP.NET AJAX in general, but one concern I have and something that has forced me to use other technologies is the size of the library. It’s about 85kb when compressed and unfortunately that is quite large if you’re trying to include it on most every page on a site (or, much much worse, every advertisement in a large Microsoft developer advertising network).

Often, the user may begin entering data into a large form, switch to some other more pressing task, then return to complete the form only to find that his session has expired and he has wasted his time. One way…

  A few weeks ago I posted about Ford SYNC, which runs on Microsoft Windows Automotive. The technology is definitely a step in the right direction, but I have to agree with Sondre, another Regional Director, that it’s not enough and really should be nearly ubiquitous by now.

  Date Published: 04 December 2007

  Introduction A fairly common task in some of the applications I work with is to provide a user with a DropDownList of options that is populated by an enum. This can easily be done with a little bit of code to bind a stock DropDownList control to the enum, but this kind of thing quickly starts to violate the DRY (Don't Repeat Yourself) principle, so I created a simple derived DropDownList control…

  A little while ago, Scotts Guthrie and Hanselman presented on MVC in ASP.NET (and Dynamic Languages) at the oddly named ALT.NET conference in Texas. I’m with ScottH that “Alt” is a pretty silly name and something like Agile or Pragmatic would be a much better descriptor. Alternative is not terribly descriptive since anything that differs from the norm is alternative, and not necessarily better. It…

• Best Web Hosting

  

  Date Published: 14 July 2006

  I just filled out a customer satisfaction survey for my hosting provider, ORCSWeb, which makes me think I should probably write a little something here in my blog about how much I like them. I’ve been using ORCSWeb’s services for what seems like forever, but off the top of my head I’d have to say at least since 2000. Before switching to them, I had used a couple of other hosting providers, all of…

  I really love charts and statistics. Give me a decent reporting application and I can spend all kinds of time analyzing data this way and that, looking for trends.

One reason for this is that charts take up a lot of room, and so you don’t want to detract from your…

  Date Published: 20 July 2005

  I haven’t officially registered for PDC yet, but I’m buying my plane tickets right now (not bad, less than $300 non stop from Cleveland). So, I’m pretty much going to be there. If you’ll be there and want to talk, look me up (email me or something via my contact form if we’ve not met). Should be fun, although the timing so close to the MVP Summit means a lot of the folks I usually see won’t be…

  
  

• More Team System Class Notes

  

  Date Published: 04 July 2005

  See Day One. Didn’t get a chance to post my notes for days two and three until now. We spent some time looking at testing in general, and the theory of why to test and how testing relates to quality. Briefly mentioned TDD and other related disciplines. In VSTS, tests are code and are versioned along with the code. The tool can auto-generate tests per method or class. The skeleton is generated…

  Date Published: 30 June 2005

  Ok, so I just finished a 3-day Ascend class on VSTS and one thing I’m disappointed by is the fact that I most likely won’t be able to use VSTS to replace SourceGear Vault immediately, since I collaborate with developers over the Internet all over the world, and VSTS does a lot of stuff via AD or direct network access. The only solution for over-the-internet work is a VPN, which at the moment I don…

  I admit it, I’ve never been a big fan of the DataReader. There are two main reasons for this. Firstly, I’m a big fan of caching, and DataReaders cannot be cached. Thus, even if they are, say, 2x as fast as a DataTable the first time, the cached DataTable is 10x faster whenever it’s read from the cached (these numbers are made up just like 87% of all statistics). Another reason I’ve shied away from…

  
  

• Writing a Days of the Week Selector Control

  

  Date Published: 13 September 2004

  No Control Required Download Code My first stab at this, keeping things as simple as possible, was just to do it on a web form without the added complication of creating a custom control. I'm storing the resulting selection in a database as in integer bitmask, where Sunday is 1 and Saturday is 64 (so values between 0000000 and 1111111 binary or 0 and 127 decimal are allowed). To do this, all…

• Bitmask Helper Function

  

  Date Published: 31 August 2004

  I had a need recently to be able to determine if a given position of an integer bitmask was set or not (for example, given the bitmask 0101 which is 5 in decimal, how would you check if the 4 position is set? — this is less obvious for, say decimal 75 — is 16 set?). Here’s the method I came up with, which could be done in one line but is broken into several for clarity and ease of debugging…

• Micro Caching Article Published

  

  Date Published: 04 May 2004

  Those of you interested in caching should read my article on AspAlliance about what I’ve termed micro-caching. Basically, the idea is that even a very short-term cache can make a big difference in site performance for a high-volume application or resource. I’d known about this in theory for some time, but I finally demo’d it to a class I was teaching at Ohio Savings Bank in April to get some hard…

  
  

• ASP.NET Micro Caching - Benefits of a One-Second Cache

  

  Date Published: 03 May 2004

  Introduction I fell in love with caching when I first started playing with it in the early versions of the ASP.NET alphas. I was aware of caching before that, but I'd never really gone to the effort to seriously implement a cache engine in an ASP app, and with ASP.NET, I didn't have to. The thing that attracts me to caching is its impact on performance without requirements (usually) for major re…

• More Breaking Changes for Whidbey – Personalization/Profile

  

  Date Published: 04 April 2004

  Personalization as a keyword/namespace has been replaced with Profile. The namespace, the config section, etc. Also, the provider model for personalization has changed between the PDC Whidbey and the March04Preview Whidbey, such that now providers must inherit from System.Web.Profile.ProfileProvider, rather than implementing a couple of (now non-existent) interfaces.

ASP.NET 1.1 and Visual Studio 2003 came about a year after that, but did not include many feature updates. ASP.NET 2.0 / Visual Studio 2005, collectively code-named 'Whidbey', have been in development since before ASP.NET 1.0 was…

  I’ve never used Newsgator before but since I just redid the RSS feed on AspAlliance.com I thought I should give it a shot and see how it works (I’ve also only recently gone to Outlook from Outlook Express (see past archives for my thoughts on the switch)). I have to say I really like it and am starting to subscribe to a bunch of blogs that previously I would manually periodically check with my…

  I’ve been redesigning AspAlliance.com off and on for the last several months, and I made a few more changes this morning. The big one that is noticeable to the general public is the URLs. Instead of having to link to articles via a viewer ASPX page and a series of querystring values, it is now sufficient to simply append the article ID to the end of the domain name (after a slash), like so: http…

  Caching in 1.x... ASP.NET Caching in 1.x is very powerful and includes three pieces: output caching, fragment caching, and the cache API. The simplest form, output caching, simply caches the output of a page. Fragment caching is a bit more granular, and caches the output of a user control. Finally, the most powerful caching functionality is achieved using the cache API, and allows any…

  Date Published: 22 September 2003

  Everyone knows (or would know if they’d read Code Complete) that ‘magic numbers’ are a bad thing in your code. Enumerated types, or Enums in .NET, are a great way to avoid such magic numbers. For instance, let’s say I have a content management system which has articles whose state can vary between Draft, Editing, and Production. I could simply use 1, 2, and 3 for these states and remember what…

  Date Published: 20 June 2003

  Here’s a little something that I term “the caching pattern” for using the ASP.NET cache object: The as keyword will try to cast Cache[key] to DataTable and if unsuccessful it will return null. If it is null, it will return null. The rest of it is pretty straightforward. This is the best practice way to get something from the cache, but look at it! It’s huge!
