ASP MVC3 - Operation could destabilize the runtime

I created a stock, empty ASP.NET MVC3 project, deployed it to my local machine, and when I pull it up in the browser I see the error below. This is a project with no code written by me (yet) so I assume it has to do with my environment. 开发者_StackOverflowAt one point this machine had an old version of ASP.NET MVC installed, but it has since been uninstalled. Skimming through the project references, every .dll is at v4.0.30319.

System.Security.VerificationException: Operation could destabilize the runtime.

Any help would be appreciated.

It's possible IIS does not have the proper Handler Mappings for .cshtml files. Check out this solution
