Charles Petzold's latest book, Applications = Code + Markup: A Guide to the Microsoft Windows Presentation Foundation, is the best WPF book available right now. Unfortuantely, all code samples in the book are written in C#. In order to help VB developers trying to learn about WPF, we are working with a couple of VB experts to convert all samples appearing in the book to VB. As we finish converting each chapter, this page will be updated with a link to sample code package.
Quick info about two experts helping us with this.
