The WPF team has just released the WPF Application Quality Guide v0.2 today, here is an online version and here is a word doc with same content. 

This release has an easy-to-navigate TOC structure, additional samples and content such as general testing concepts, test strategies, WPF programming stack, visual verification testing, media testing, animation and transition testing, performance and scalability testing, security testing, data binding and interop. It also provides a tools section where you can find the tools for creating, debugging, profiling and test WPF apps and components.
