使用 VirtualPathProvider 从 DLL 加载 ASP.NET MVC 视图

基于这个问题here并使用代码发现here，我正在try 加载视图，这些视图是一个单独的DLL项目中嵌入的资源，原始问题的作者说他已经成功地做到了这一点-但是我无法让它工作，因为MVC视图引擎似乎正在拦截请求，并且仍然在查看视图的文件系统.例外情况:

Server Error in '/' Application.
The view 'Index' or its master could not be found. The following locations were searched:
~/Views/admin/Index.aspx
~/Views/admin/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx
~/App/Views/admin/Index.aspx
~/App/Views/admin/Index.ascx
~/App/Views/Shared/Index.aspx
~/App/Views/Shared/Index.ascx 

我使用的是CustomViewEngine，比如Rob Connery的/App structure one，如下所示:

public class CustomViewEngine : WebFormViewEngine
    {
         public CustomViewEngine()
         {
             MasterLocationFormats = new[] { 
                "~/App/Views/{1}/{0}.master", 
                "~/App/Views/Shared/{0}.master" 
                };

             ViewLocationFormats = new[] { 
                "~/App/Views/{1}/{0}.aspx", 
                "~/App/Views/{1}/{0}.ascx", 
                "~/App/Views/Shared/{0}.aspx", 
                "~/App/Views/Shared/{0}.ascx" 
                };

             PartialViewLocationFormats = ViewLocationFormats;
         }
    }

以下是我的路由:

    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute("Home", "", new {controller = "Page", action = "Index", id = "Default"});
    routes.MapRoute("Default", "Page/{id}", new { controller = "Page", action = "Index", id = "" });
    routes.MapRoute("Plugins", "plugin/{controller}/{action}", new { controller = "", action = "Index", id = "" });
    routes.MapRoute("Error", "{*url}", new { controller = "Error", action = "ResourceNotFound404" });

在我的AssemblyResourceProvider中，我判断路径是否从~/plugin/开始，然后使用dll文件名约定plugin.{controller}.dll

有什么建议吗？

UPDATE:当路由的http://localhost/plugin/admin请求到达VirtualFileProvider时，它的末尾没有附加任何视图.因此，在VirtualFileProvider的Open方法中，~/plugin/admin的虚拟路径被传入，而实际上它应该是~/plugin/admin/Index.aspx，正如我在上面的路由中定义的那样.我是不是搞砸了我的路由，或者我预料到这会发生是对的吗？
