Jessica grouped a series of articles on learning WPF:
"Getting started in WPF
I’ve put together a series of articles on WPF, from a Windows Forms developer perspective. This started out as a simple document entitled “So you know Windows Forms and you wanna learn Avalon” way before there was as much content out there as there is now. I hope this twist in perspective is useful for folks.
Very special thanks to Mark Boulter for his content which has been incorporated into these articles.
Hope you have as much fun as I did learning WPF,
Jessica (AKA JFo)"
