I\'ve been trying to get to the bottom of an issue with binding the SelectedItem of my ComboBox and since I\'ve had not success thusfar I started looking at ways to get more
It's a setting in the Visual Studio 2010:
Tools -> Options -> Debugging -> Output Window -> WPF Trace Settings -> Data Binding -> set to Warning (or whatever you like).
Standard was Off.
This solution worked for me.
