T4MVC 3.7.4 doesn't work in VS 2013 (in VS 2012 it is working just fine)

Question

I created a new ASP.NET MVC Web Application project in VS 2013 and installed T4MVC package via nuget. I'm receiving this error below when I am trying to Run Custom Tool for T4MVC.tt in the action menu. Line 792 in T4MVC.tt looks like this:

if (method.Type.TypeKind != vsCMTypeRef.vsCMTypeRefCodeType || !(method.Type.CodeType is CodeClass2)) continue;

Some questions/suggestions to help investigate:

• Is your solution a completely unmodified new MVC5 project, or does it have some of your changes?
• Does this happen consistently, even after restarting VS?
• Do you see the same problem with my sample solution?
