As I wanted to try something basic, like Message box or opening notepad.
I got this message:
Main has thrown an exception

Message: Value cannot be null.
Parameter name: ReferencedAssemblies

Exception Type: Exception

System.Exception: Value cannot be null.
Parameter name: ReferencedAssemblies

or attach the xaml
