Thanks for the code snippet Dare!

I was hoping for a stronger typing using some client libraries so that i dont have to deal with the raw http response.  if you look at the Google Contacts API set, they provide .Net client libraries for interacting with the  gmail contacts.

Microsoft released some PHP server-side code here:

I just released a translation of the PHP code to C#, feel free to use it.
