In this post you can find a few links to some great articles about the WPF controls.
So in my work with WPF, I’ve needed either controls to supplement what
was missing from Winforms or simply to match up with the current user
experience’s of today’s application. I take no credit in actually
developing these controls, just finding them on the web via Google. FYI
– this article was written on .NET 3.5 as I know some of these will be
included with .NET 4.0 WPF.
