I've been developing now for the last few months my first WPF application.  During this development I've searched for lots of information on how to implement WPF and some of the quirks and workarounds needed to make my app function.  My goal is to post some useful links as well as some useful articles of my own to help those with WPF development.

Josh Smith on WPF (A good blog on WPF and some useful articles)
WPF Wonderland (Another good blog on WPF)
WPF Wiki (A wiki for WPF)
MSDN WPF Forums (MSDN forums for WPF discussion)
IRhetoric - Karsten Januszewski (Another WPF blog)

The links above are just a small selection of WPF information out there, since its still a new technology more and more information becomes available, you're best bet is to use these links as a launching platform into the world of WPF.
