The pre-application start initialization method Ru

Question

I'm trying to run an ASP MVC 4 application on IIS. When I publish MVC 4 application from Basic template - without any dependencies apart from these made by the wizard - application works. But when I publish other application, that is using WebActivator and many other libs, I see this error:

Could not load file or assembly 'System.Core, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047) 

And complete stack trace:

Is is IIS6 related issue, or I'm missing something on the server?
