I tried implementing Phil's Areas Demo in my project

<http://haacked.com/archive/2008/11/04/areas-in-aspnetmvc.aspx>.

I appended the Areas/Blog structure in my existing MVC project and I get the following error in my project.

The controller name `Home` is ambiguous between the following types:

```
WebMVC.Controllers.HomeController
WebMVC.Areas.Blogs.Controllers.HomeController 

```

this is how my `Global.asax` looks.

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

    routes.MapAreas("{controller}/{action}/{id}",
        "WebMVC.Areas.Blogs",
        new[] { "Blogs", "Forums" });

    routes.MapRootArea("{controller}/{action}/{id}",
        "WebMVC",
        new { controller = "Home", action = "Index", id = "" });

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

}

protected void Application_Start()
{
    String assemblyName = Assembly.GetExecutingAssembly().CodeBase;
    String path = new Uri(assemblyName).LocalPath;
    Directory.SetCurrentDirectory(Path.GetDirectoryName(path));
    ViewEngines.Engines.Clear();
    ViewEngines.Engines.Add(new AreaViewEngine());
              RegisterRoutes(RouteTable.Routes);
   // RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes);

}

```

If I remove the `/Areas/Blogs` from `routes.MapAreas`, it looks at the Index of the root.
