Need help with Castle.Windsor as an Asp.Net MVC ControllerFactory please.

Question

I'm trying to implement Steven Sanderson's WinsorControllerFactory from his pro Asp.Net MVC Framework book (great book, btw) and I'm stumbling into an issue. I'm not sure what else you'll need to know in order to formulate a response but I greatly appreciate any help in this. Thanks!

Here's the code:

WindsorControllerFactory

public class WindsorControllerFactory : DefaultControllerFactory
{
    private WindsorContainer _container;

    public WindsorControllerFactory()
    {
        _container= new WindsorContainer(new XmlInterpreter(new ConfigResource("castle")));
        var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes()
                              where typeof (IController).IsAssignableFrom(t)
                              select t;
        foreach(Type t in controllerTypes)
        {
            _container.AddComponentLifeStyle(t.FullName, t, LifestyleType.Transient);
        }
    }
    protected override IController GetControllerInstance(Type controllerType)
    {
        return (IController)_container.Resolve(controllerType);
    }
}

Web.Config

  <castle>
    <components>
      <component id="MenuRepository"
                 service="****.IMenuRepository, ****.Model"
                 type="****.FakeMenuRepository, ****.Model">
      </component>
      <component id="NewsRepository"
                 service="****.INewsRepository, ****.Model"
                 type="****.FakeNewsRepository, ****.Model">
      </component>
    </components>
  </castle>

NewsArticleController

public class NewsArticleController : Controller
{
    private INewsRepository _repository { get; set; }
    public NewsArticleController(INewsRepository repository)
    {
        _repository = repository;
    }

Global.asax

    protected void Application_Start()
    {
        RegisterRoutes(RouteTable.Routes);
        ControllerBuilder.Current.SetControllerFactory((new WindsorControllerFactory()));
    }

ERROR MESSAGE No component for supporting the service ****.NewsArticleController was found Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

The S#arpArchitecture project has a decent implentation of using Windsor as a DI framework (for controllers or anything else), with little or no need to add web.config sections - http://code.google.com/p/sharp-architecture/

Code examples:

CastleWindsor/ComponentRegistrar.cs:

public class ComponentRegistrar
{
    public static void AddComponentsTo(IWindsorContainer container) {
        AddGenericRepositoriesTo(container);
        AddCustomRepositoriesTo(container);

        container.AddComponent("validator",
            typeof(IValidator), typeof(Validator));
    }

    private static void AddCustomRepositoriesTo(IWindsorContainer container) {
        container.Register(
            AllTypes.Pick()
            .FromAssemblyNamed("Northwind.Data")
            .WithService.FirstNonGenericCoreInterface("Northwind.Core"));
    }

    private static void AddGenericRepositoriesTo(IWindsorContainer container) {
        container.AddComponent("entityDuplicateChecker",
            typeof(IEntityDuplicateChecker), typeof(EntityDuplicateChecker));
        container.AddComponent("repositoryType",
            typeof(IRepository<>), typeof(Repository<>));
        container.AddComponent("nhibernateRepositoryType",
            typeof(INHibernateRepository<>), typeof(NHibernateRepository<>));
        container.AddComponent("repositoryWithTypedId",
            typeof(IRepositoryWithTypedId<,>), typeof(RepositoryWithTypedId<,>));
        container.AddComponent("nhibernateRepositoryWithTypedId",
            typeof(INHibernateRepositoryWithTypedId<,>), typeof(NHibernateRepositoryWithTypedId<,>));
    }
}

Global.asax (primary initialization method for di):

protected virtual void InitializeServiceLocator() {
        IWindsorContainer container = new WindsorContainer();
        ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));

        container.RegisterControllers(typeof(HomeController).Assembly);
        ComponentRegistrar.AddComponentsTo(container);

        ServiceLocator.SetLocatorProvider(() => new WindsorServiceLocator(container));
    }

MvcContrib offers some extension methods for registering controllers in Windsor, example:

windsorContainer.RegisterControllers(Assembly.GetExecutingAssembly());

Mannish's code uses the same extension method.
