Mvc area routing?

Question

Area folders look like :

Areas 
    Admin
        Controllers
            UserController
            BranchController
            AdminHomeController

Project directories look like :

Controller
    UserController
        GetAllUsers

area route registration

public override void RegisterArea(AreaRegistrationContext context)
{
    context.MapRoute(
        "Admin_default",
        "Admin/{controller}/{action}/{id}",
        new { action = "Index", id = UrlParameter.Optional },
        new { controller = "Branch|AdminHome|User" }
    );
}

project route registration

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
        namespaces: new string[] { "MyApp.Areas.Admin.Controllers" });
}

When I route like this: http://mydomain.com/User/GetAllUsers I get resource not found error (404). I get this error after adding UserController to Area.

How can I fix this error?

Thanks...

You've messed up your controller namespaces.

Your main route definition should be:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
    namespaces: new string[] { "MyApp.Controllers" }
);

And your Admin area route registration should be:

public override void RegisterArea(AreaRegistrationContext context)
{
    context.MapRoute(
        "Admin_default",
        "Admin/{controller}/{action}/{id}",
        new { action = "Index", id = UrlParameter.Optional },
        new { controller = "Branch|AdminHome|User" },
        new[] { "MyApp.Areas.Admin.Controllers" }
    );
}

Notice how the correct namespaces should be used.

An up to date solution for ASP.NET Core MVC.

[Area("Products")]
public class HomeController : Controller
