Can't find Controller in MVC 3 project - NotFound error

Question

I have this global.asax file with this code:

routes.MapRoute("Invitations", 
                        "api/invitations", 
                        new { controller = "Invitations", action = "Invitation"});

And I have a Controller:

public class InvitationsController : Controller
{
    [HttpPut]
    public JsonResult Invitation(InvitationResponse invitationResponse)
    {
        //code
    }
}

And I'm accessing the controllers by HttpWebRequest with this URL:

"http://localhost:6055/API/Invitations"

When I run this I get the error "NotFound".

EDIT:

The whole global route:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute("Users",
                        "api/users/{id}",
                        new { controller = "Users", action = "UserAction", id = UrlParameter.Optional });


        routes.MapRoute("CheckIn",
                        "api/checkins",
                        new { controller = "CheckIn", action = "CheckIn" });

        routes.MapRoute("Appointments",
                        "api/appointments/{id}",
                        new { controller = "Appointments", action = "Appointment", id = UrlParameter.Optional });

        routes.MapRoute("UserAppointments",
                        "api/users/{userId}/appointments/{startDate}",
                        new { controller = "Appointments", action = "UserAppointments", startDate = UrlParameter.Optional });

        routes.MapRoute("UserInvitations",
                        "api/users/{userId}/invitations",
                        new { controller = "Invitations", action = "UserInvitations" });

        routes.MapRoute("UserOverview",
                        "api/users/{id}/overview",
                        new { controller = "Users", action = "Overview" });

        routes.MapRoute("Invitations", 
                        "api/invitations", 
                        new { controller = "Invitations", action = "Invitation"});

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
        );

I don't know if this tester works on MVC3 (it works on MVC2) but you can try it, it's a great tool for testing your route configuration. — Gabe Thorns
I tested the tester and i get that it mathes the current request — user1156691
Then your routes seem to be configured correctly, and your request should hit the controller/action. It the request not matching any other route that is higher in the route hierarchy? — Gabe Thorns
Those routes is all im using. Do you see any route that is higher in the hierarchy? — user1156691
MVC matches the requests with the routes in order, so for instance if you place a general route (like "Default") before (that is, place the code at the top of the route configuration). MVC will match that first. The questions was if, in the tester, your "/API/Invitations" is not matching other route that comes before your "Invitations" route? — Gabe Thorns

"http://localhost:6055/API/Invitations" doesn't look correct, shouldn't it be

"http://localhost:6055/YourApp/API/Invitations"
