Why can't I put the webform into Views\Home folder?

I'm using ASP.NET MVC 5.2.2.0 (C#) within Webform.
When I follow this step:

right click solution -> Add -> New item -> create new webform

After debugging, that's work without a problem when I type "localhost/webform1.aspx" on url.
But, when I do this:

right click Views\Home folder -> Add -> Web form -> ok

In HomeController.cs

public ActionResult Test()
{
return View("webform2");
}

In RouteConfig.cs

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.IgnoreRoute("{WebForm}.aspx/{*pathInfo}");
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }

It gave to me an error when I type "localhost/home/test" on url:

The view at '~/Views/home/webform2.aspx must derive from ViewPage, ViewPage<TModel>...'

My question is: Can't webform be created in Views\Home folder?
If possible, can you tell me how to do that?

Thank you!
