Look in the method Application_Start in the file Global.asax.cs. You have a null reference there. Put a try/catch and use the debugger to see which object is null.

If you deploy the pdb files with your dll the stack trace will also contain the line number. Also do set the Debug Info to full: Project Properties -> Build -> Advanced -> Debug Info (http://stackoverflow.com/a/3791997/57369)

    I don't think that "+133" is a line number (see the other numbers), but the problem *is* in that method. – Hans Kesting Dec 06 '12 at 10:33
  • Indeed I read too fast (assumed it was ":" and not +). So in this case it's an offset and not a line number. I will edit my answer. – Gabriel Dec 06 '12 at 10:59
