MVC3 with Razor throws Method not found: 'System.Object System.Web.Mvc.ControllerBase.get_ViewModel()'

Fresh IIS7.5 installation on Win Server 2008 R2.

Installed MVC3 etc. via Web Platform Installer.

Made a basic MVC3 application locally. Just "new project" without anything to it. Made an application on the IIS to host the application. AppPool set to .Net4.

When I run the application locally I get this:

Blockquote

I'm lost!

I don't think you are actually loading MVC 3 in IIS. Sounds like you're getting MVC 2 instead. Double-check your MVC 3 installation on the server. Also examine the bindingRedirect in Web.Config.
