Have you installed .NET Framework 4.5 or Visual Studio 2012? The problem is most likely a bug in the framework. You may find your answers here:

Answer 2

We had a similar issue with one of our projects. We had been using MVC3 and tried upgrading to MVC4. We also upgraded to Razor 2.0. Turned out that the web.configs did not all update as expected. Check your web config in the ~/Views folder as well as the root web.config and make sure the assembly binding redirects are correct and all the assembly references are correct. We did that and the issue went away
