    99.99999% of the time (yes, I measured it), a controller in ASP.NET MVC is a type, and an action is a method — with reflection as the glue that holds it all together. For most folks, that’s the best way to view how ASP.NET MVC works. But some folks like to dig deeper and get their hands dirty a bit by taking a peek under the hood. Doing so reveals that while the reflection based mapping of controllers types and actions to methods is true by default, it can be easily changed to something else...

    A few months ago I blogged about using Model metadata to render a dynamic UI in MVC 2. The scenario in the post was that we might have a view model where the questions are conditionally displayed and therefore a dynamic UI is needed. To recap the previous post, the solution was to use a custom attribute called [QuestionId] in conjunction with an “ApplicableQuestions” collection to identify whether each question should be displayed. This allowed me to have a view model that looked like this: ...

    Last week I was in the middle of re-writing an old MVC application. The app was written during the early days of MVC, and as a consequence it was a playground for learning and experimentation. As a developer, I am continuously learning new tricks so its’ no surprise that when I look at the code I wrote a few years ago, I generally will feel the urge to refactor it. For example, when I started out with ASP.NET MVC I did not fully understand how the model binders worked. Unfortunately, this mean...

    I’m struggling with an interesting problem with WCF REST since last night and I haven’t been able to track this down. I have a WCF REST Service set up and when accessing the .SVC file it crashes with a version mismatch for System.ServiceModel: Server Error in '/AspNetClient' Application. Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.Description: An unhandled exception occ...

    Microsoft’s new Razor HTML Rendering Engine that is currently shipping with ASP.NET MVC previews can be used outside of ASP.NET. Razor is an alternative view engine that can be used instead of the ASP.NET Page engine that currently works with ASP.NET WebForms and MVC. It provides a simpler and more readable markup syntax and is much more light weight in terms of functionality than the full blown WebForms Page engine, focusing only on features that are more along the lines of a pure view engine...
