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

Question

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?

worth adding - this started as an MVC Preview 1 app, I have since installed MVC Preview 2 via the Platform installer — SteveCl, Dec 21 '10 at 14:36
1 more! I set a breakpoint on the RegisterArea method in my Postcard AreaRegistration - which is hit. I also set a break point on the constructor of the Controller (and the Index Action) neither are hit? — SteveCl, Dec 21 '10 at 14:43
Please provide more information. What does your controller look like? — Haacked, Dec 21 '10 at 21:57

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.

+1, If you implement areas you should go back and update ALL of your routes to include the namespaces you want the route isolated to. This would cause issues if you had a controller of the same name, like 'Home" in both the root and in an area. – Nick Bork Apr 20 '12 at 20:31
In my case, the solution was similar to the one proposed here: I copy/pasted the AreaRegistration, but forgot to update the namespace as well. – Bertvan Oct 21 '12 at 15:37

You were missing the controller part in your maproute

Try to add a class PostCardAreaRegistration under PostCard Area

using System.Web.Mvc;

namespace Areas.PostCard
{
    public class PostCardAreaRegistration: AreaRegistration 
    {
        public override string AreaName 
        {
            get 
            {
                return "PostCard";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context) 
        {
            context.MapRoute(
                "PostCard_default",
                "PostCard/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}
