XAML C# solution not work at all

I did try 2d toolkit with new unity and recived script errors and plain screen after compilation as XAML + C#. Same with other components, just errors in different levels

Good thing everything works with XAML C++ solution for Windows 8.

Do someone know why it so?

Do someone see same behavior?

Thank you for any help.

PS It is not 100% repro. I did make clean project with just 2dtoolkit and it did work.

Can you provide the exact error messages you get?
