Routing doesn't work for ASP.NET MVC4 running on Mono

MVC4

Run an ASP.NET MVC4 application on Mono 3.2.8. When the controller action returns string,
for example:
public string Index()
{
return "MVC4 Page...";
}

the browser renders OK,
but when the controller action returns View(), for example:

public ActionResult Index()
{
return View();
}

The error messages are as follows:

System.InvalidOperationException
The view 'Index'or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Home/Index.aspx
~/Views/Home/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx
~/Views/Home/Index.cshtml
~/Views/Home/Index.vbhtml
~/Views/Shared/Index.cshtml
~/Views/Shared/Index.vbhtml


However, ~/Views/Home/Index.cshtml does exist.


How do I solve the problem?
