System.Reflection.TargetInvocationException; need help understanding

Question

这个例外是什么意思，我该怎么做才能解决它？

Answer 1

From MSDN:

The exception that is thrown by methods invoked through reflection. This class cannot be inherited.

Try to see what the InnerException says or take a look at the StackTrace to see what happens.

EDIT: Looking at your StackTrace it seems that occurs a problem while creating an element in your XAML. Check InnerException as said before to have more informations.
