I've recently encountered similar problem when i was compiling a modified version of asp.net MVC 4 and importing the new DLL into the project.

Somehow i was referencing the old versions of the DLLs in the web.config (including the web.config in the views folder)

The error in my case was thrown because the two DLLs were different versions. 4.0.0 and 4.1.0. Maybe you should look into that. Maybe specify a version of the compiled files (i'm guessing DLLs)

I hope this helps you fix the problem.

other tips: I'm guessing you have some sort of version control system? if yes , revert all the changes back before this started and look carefully at the code and which models/controls change and how. if you are not using VCS... there isn't much you can do to revert the changes. And you should start using a VCS.
