razor

问题 I have upgraded to MVC3 and Razor, everything works fine. However, in my return View(model); the "View" is red and VS2010 will helpfully suggest I generate a view. When I do, it generates a aspx/WebForms view. There's no other aspx files in the project, and if I run the project, the Razor view engine works fine.

The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.

I tried using the UriHelper.NavigateTo but does not work with non Blazor component routes. Then I tried with a Javascript call to do a window.location, but the issue is that this causes a browser refresh that
