Custom RazorViewEngine gives page error

Question

I am trying to implement my own viewing engine using Razor. The goal is that the view is in a subfolder to use this view.

I have a view engine derived from RazorViewEngine

public class RazorViewFactory : RazorViewEngine { public RazorViewFactory() { string TenantID = ConfigurationManager.AppSettings["TenantID"]; if (TenantID != null) { MasterLocationFormats = new[] { "~/Views/Shared/{0}.cshtml" }; ViewLocationFormats = new[]{ "~/Tenant/" + TenantID + "/Views/{1}/{0}.cshtml", "~/Tenant/" + TenantID + "/Views/Shared/{0}.cshtml", "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" }; PartialViewLocationFormats = new[] { "~/Tenant/" + TenantID + "/Views/{1}/{0}.cshtml", "~/Tenant/" + TenantID + "/Views/Shared/{0}.cshtml" }; } } 

}

and in my Global.asax

  protected void Application_Start() { ... ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new RazorViewFactory()); } 

Everything works, except when I load the Tenant submenu home page, I get the following error.

 The view at '~/Tenant/TenantB/Views/Home/Index.cshtml' must derive from WebViewPage, or WebViewPage<TModel>. 

If I load the base home page, it works fine with the Razor engine.

You need to copy the web.config from the Views folder to the Tenant folder (or make sure that it has the same configuration sections as described here: Razor HtmlHelper Extensions (or other namespaces for views) Not found )
