Abstracting away issues of HttpContext from your ASP.NET MVC controllers
Feb 1203I've noticed that I write software in one of three modes: For myself: Shortcuts, less testing, not well-factored. For myself but in public: Mostly POP Forums, which I try to avoid letting it suck since others will use it and see the code. For sharing: Any day job or gig where others will use or maintain your code. You don't want to unleash crapsauce on others. I have to admit that second case isn't the most clean of endeavors. While I'm generally happy with the forum app and the feedba...

What’s new in ASP.NET MVC 4: slides and demo are now online
Jan 1217Today I had my first live webcast for Microsoft Belgium, about the new features released with ASP.NET MVC 4 at Build in September. There were around 80+ people registered and around 50 people attending, and almost nobody left before the end of the webcast, so I guess it pretty well. We also are aware there were some glitches in the audio during the async part of the webcast: the audio was also recorded directly from the mic, so the video that will be published in the next week on Channel9 wi...

A Really Empty ASP.NET MVC 3 Project Template
Jan 1211In the ASP.NET MVC 3 Uservoice site, one of the most voted up items is a suggestion to include an empty project template. No, a really empty project template. You see, ASP.NET MVC 3 includes an “empty” project template, but it’s not empty enough for many people. So in this post, I’ll give you a much emptier one. It’s not completely empty. If you really wanted it completely empty, just choose the ASP.NET Empty Web Application template. The Results I’ll show you the results first, and then t...

The evolution of asynchronous controllers in ASP.NET MVC
Jan 1209Asynchronous operations in ASP.NET MVC have always been left a bit behind. They appeared in ASP.NET MVC 2, remained untouched in v3, but now in MVC 4 (especially in combination with C# 5 and async/await) they reached the same easiness of use of the standard synchronous controller. Now (or better, in a few months with the release of ASP.NET MVC 4, .NET 4.5 and C# 5) you can write public async Task<ViewResult> Stuff() { return View(await DoStuff("Some stuff")); } In this post I’m going to...

XmlWriter and lower ASCII characters
Jan 1202Ran into an interesting problem today on my CodePaste.net site: The main RSS and ATOM feeds on the site were broken because one code snippet on the site contained a lower ASCII character (CHR(3)). I don't think this was done on purpose but it was enough to make the feeds fail. After quite a bit of debugging and throwing in a custom error handler into my actual feed generation code that just spit out the raw error instead of running it through the ASP.NET MVC and my own error pipeline I foun...

ASP.NET MVC + Selenium + IISExpress
Dec 1122The goal of this blog entry is to explain how you can create integration tests for ASP.NET MVC applications by using a combination of Selenium WebDriver and IISExpress. Integration tests are useful when you want to test an entire user story. For example, you might want to test whether a user can successfully add an item to a shopping cart. Adding an item to a shopping cart might require the execution of C# code, database code, and JavaScript code. Using an integration test, you can verify t...

What's new in ASP.NET MVC 4 webcast: 17 January
Dec 1122ASP.NET MVC 4 is the new version of ASP.NET MVC that came out during Build in September: it included a few pretty interesting features like a newly revamped project template, a better asynchronous controller and, the main feature, native support for mobile version of the site, with device detection and mobile only views. Also some productivity enhancement were introduced, like recipes to automate repetitive coding tasks. And finally, if you run ASP.NET MVC 4 on top of ASP.NET 4.5, you also g...

Using QUnit with Razor Layouts
Dec 1111Given how central JavaScript is to many modern web applications, it is important to use unit tests to drive the design and quality of that JavaScript. But I’ve noticed that there are a lot of developers that don’t know where to start. There are many test frameworks out there, but the one I love is QUnit, the jQuery unit test framework. Most of my experience with QUnit is writing tests for a client script library such as a jQuery plugin. Here’s an example of one QUnit test file I wrote a ...

Set the AsyncTimeout attribute for your async controllers
Dec 1107Today I decided to convert an action that was making various long calls to external webservices to be asynchronous. With the synchronous version it was long but still under the default script timeout of ASP.NET, so I was very surprised when the async version was returning a System.TimeoutException, even if it was still taking the same amount of time. I tried increasing the ScriptTimeout, but still no luck: the page was timing out. After a bit of searching online I found out that for some str...

Web Forms Model Binding Part 3: Updating and Validation (ASP.NET 4.5 Series)
Oct 1131This is the fifth in a series of blog posts I’m doing on ASP.NET 4.5. The next releases of .NET and Visual Studio include a ton of great new features and capabilities. With ASP.NET 4.5 you’ll see a bunch of really nice improvements with both Web Forms and MVC – as well as in the core ASP.NET base foundation that both are built upon. Today’s post is the third of three posts in the series that talk about the new Model Binding support coming to Web Forms. Model Binding is an extension of the ...
