With these it helps Yours is the second report for this bug. I've filed issue #109 to track this. Incidentally, I believe the samples are correct, since MVC 3 works fine on .NET 3.5, as far as I can tell. Although a known bug was that if MVC 4 is also installed on your machine that you build the samples on, they incorrectly bind to MVC 4 DLLs and result in a runtime failure.
