Single Action Controller - Take 2

After almost a year of using the first version of Single Action Controllers over the ASP.NET MVC (http://rodolfograve.blogspot.com/2011/05/teamcommons-mvc-single-responsibility.html), I have applied a few improvements on it. I particularly didn't like the requirement to inherit from a custom class (SingleActionController), and the boilerplate code required in your Global.asax.

So, the current implementation (also available as a NuGet package at http://nuget.org/packages/TEAM.Commons.Web) doesn't require your controller class to inherit from SingleActionController but from the usual Controller class, and provides a helper method for Autofac users:

Global.asax:

protected void Application_Start()
{
  var builder = new ContainerBuilder();

  // Register your dependencies

  builder.RegisterTypesForSingleActionControllers(Assembly.GetExecutingAssembly(), "Base namespace of your controllers");
}

A controller:

using MyCompany.MyProject.ViewModels.Author;

// Name your namespace after your controller.
// This works very nicely with the directory structure you create in your project.
namespace MyCompany.MyProject.Controllers.Author
{
  // Name your class after your Action and make it inherit from the standard Controller
  public class Index : Controller
  {
    // One single action named Execute
    public ActionResult Execute(FilterDataModel filter) { ... }
  }
}
