Having issue with multiple controllers of the same name in my project

Question

I am running into the following error with my ASP.NET MVC 3 project:

Multiple types were found that match the controller named 'Home'. This can happen if the route that services this request ('Home/{action}/{id}') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.

The request for 'Home' has found the following matching controllers: MyCompany.MyProject.WebMvc.Controllers.HomeController MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController

I have a HomeController in my default controller folder, with a class name of MyCompany.MyProject.WebMvc.Controllers.HomeController.

My RegisterRoutes method, in my global.asax, looks like:

    public static void RegisterRoutes(RouteCollection routes)     {         routes.IgnoreRoute("{resource}.axd/{*pathInfo}");          routes.MapRoute(             "Default", // Route name             "{controller}/{action}/{id}", // URL with parameters             new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults         );     } 

I then have an area called Company, with a HomeController in the default controller folder for the area, with a class name of MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController.

The RegisterArea method in the CompanyAreaRegistration file looks like:

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

This is all leading the error I highlighted at the beginning of this post. I am struggling trying to piece together a solution from various other posts, with NO LUCK.

Is it possible to have a HomeController in the default controllers folder and then one in EACH area? If so, do I need to make (assuming I do) changes to my configuration file to make this work?

Any help would be much appreciated!

The error message contains the recommended solution: "If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter."

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

This will make http://server/ go to your HomeController's Index action which is, I think, what you want. http://server/company/home will go to the Company area's HomeController's Index action, as defined in the area registration.
