Cannot resolve view of the parent controller

Question

Create a controller:

public abstract class MyBaseController : Controller
{
   public ActionResult MyAction(string id)
   {
      return View();
   }
}

Than create another specific controller that inherit from MyBaseController:

public class MyController : MyBaseController 
{

}

There is a view called MyAction.aspx in the Views/MyBaseController folder Then, call MyController/MyAction method. Following exception will be generated:

The view 'MyAction' or its master could not be found. The following locations were searched: ~/Views/MyController/MyAction.aspx ~/Views/MyController/MyAction.ascx ~/Views/Shared/MyAction.aspx ~/Views/Shared/MyAction.ascx

Can I make MVC.NET to use the view from Views/MyBaseController folder?

you should wait for a more finesse answer but this work:

Create a new view engine based on the default one and override the FindViewMethod this way:

 public class MyNewViewEngine : WebFormViewEngine
 {
     public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
     {
        var type = controllerContext.Controller.GetType();

            //Retrieve all the applicable views.
            var applicableViews = from m in type.GetMethods()
                                  where typeof(ActionResult).IsAssignableFrom(m.ReturnType) & m.Name == viewName
                                  select m;

            //Save the original location formats.
            var cacheLocations = ViewLocationFormats;
            var tempLocations = cacheLocations.ToList();

            //Iterate over applicable views and check if they have been declared in the given controller.
            foreach(var view in applicableViews)
            {
                //If not, add a new format location to the ones at the default engine.
                if (view.DeclaringType != type)
                {
                    var newLocation = "~/Views/" + view.DeclaringType.Name.Substring(0, view.DeclaringType.Name.LastIndexOf("Controller")) + "/{0}.aspx";
                    if (!tempLocations.Contains(newLocation))
                        tempLocations.Add(newLocation);
                }
            }

            //Change the location formats.
            ViewLocationFormats = tempLocations.ToArray();

            //Redirected to the default implementation
            var result = base.FindView(controllerContext, viewName, masterName, useCache);

            //Restore the location formats
            ViewLocationFormats = cacheLocations;

            return result;
   }
}

Add the new view engine:

 public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            ViewEngines.Engines.Clear();
            ViewEngines.Engines.Add(new MyNewViewEngine());
            RegisterRoutes(RouteTable.Routes);
        }
    }

hope this helps
