Snoop for WPF 4

 Not sure if folks aware that Snoop for WPF 4.0 has been available for a while.
You can download it from here.

This version includes other impressive list of improvements that you can read about here.
Thanks to Corry Plotts and others (Dan Hanan, Mark Kharitonov, etc) who improved on Pete Blois’ original Snoop.
