Q:

MVC 3 - New Area - 404 error - Resource not found - have tried route debugger

I have a small MVC 3 app - bit of a demo ground.
I have one area and thats been working fine.
I have just added another area expecting to just spin up the app and it work - but no, 404 - The resource cannot be found.
The map route in the AreaRegistration is the default (as is the first area i created).
public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            "Postcard_default",
            "Postcard/{controller}/{action}/{id}",
            new { action = "Index", id = UrlParameter.Optional }
        );
    }

I have tried adding in a specific controller into this, but nothing.
So I downloaded Phil Haack's RouteDebugger and my route is found when typing in http://server/Postcard/Create (which is where I am trying to get too)
Structure of the Area

My controller
    public class CreateController : Controller
{
    private ILogger Logger { get; set; }
    private ICardSender Emailer { get; set; }
    private IOCCardRepository CardRepository { get; set; }

    public CreateController(ILogger logger, ICardSender cardSender, IOCCardRepository repository)
    {
        this.Logger = logger;
        this.Emailer = cardSender;
        this.CardRepository = repository;
    }

    //
    // GET: /Postcard/Create/

    public ActionResult Index()
    {
        var model = new OCPostcardModel().Create();

        return View(model);
    }

NOW: I have since deleted the entire area, tried again it didn't work. So I added in the specific controller in the route (Inside AreaRegistration file)
context.MapRoute(
            "Postcard_default",
            "Postcard/{controller}/{action}/{id}",
            new { controller = "Create", action = "Index", id = UrlParameter.Optional }
        );

And its working...I don't know why it didn't work when I did this before, but it is now.
Still curious though as I've not seen anyone add in this controller into route in any of the demo's i've looked at - and I haven't got it in my other area?

A:

I ran into this when I moved a controller into an Area but forgot to update the namespace. The controller name is scoped to the Area's namespace. So "Some" in "Area" will map to App.Areas.Area.Controllers.SomeController, which didn't exist.

A:

You were missing the controller part in your maproute
