The WPF Wiki – Good WPF Resource Center

If you are looking for a good resource for WPF material, I came across this one this morning while looking for WPF stuff.  The WPF Wiki.  I just started out on the All Pages portion and there are quite a few pages already in place, of which the 2nd page listed is a WPF Resources page.  I was specifically looking for creating a collection in XAML, and found it right here with good code samples.  Some of the pages are lacking in meaty material (such as the What is XAML, which has a reference back to Wikipedia), but all in all it looks like a good resource and of course will get better.
