Installed Umbraco 7.0.1 and added code for surfacecontroller. Same code works fine for Umbraco 6.1.6 but it is not working for Umbraco 7.

When I try /umbraco/surface/homesurface it is giving me 404 error.

public class HomeSurfaceController : Umbraco.Web.Mvc.SurfaceController
{
    //
   // GET: /Home/
   public ActionResult Index()
   {
      return Content("home control");
   }
}
