Error: Inheritance security rules violated by type: 'System.Web.WebPages.Razor.WebPageRazorHost'

Question

Out of nowhere my ASP.NET MVC 4 solution gives me this error:

Inheritance security rules violated by type: 'System.Web.WebPages.Razor.WebPageRazorHost'. Derived types must either match the security accessibility of the base type or be less accessible.

I Googled the problem and everybody says it has happened when anyone updates the solution from one version to another. But I didn't update my solution, just change the IDE from VS12 to VS13. Is this what creates the problem?

The full stack trace is as follows:

[TypeLoadException: Inheritance security rules violated by type: System.Web.WebPages.Razor.WebPageRazorHost'.

From my friend Claudio Redi's comment the solusion of this problem is:

Try removing the System.Web.Razor assembly binding in the web.config if present. http://forums.asp.net/t/1968686.aspx?Installed+Nuget+package+Razor+Engine+whole+system+stops
