Windows Presentation Foundation (WPF) Application Quality Guide

The WPF Team has posted a WPF Application Quality Guide.

Introduction (from Guide's web site)
In light of the rapid adoption of the WPF and the continuous requests from partners and customers, the WPF team at Microsoft is happy to present the first release of the "WPF Application Quality Guide". We plan to release the Guide in stages, updating and fine-tuning the content, based on feedback provided by you. This first release of the Guide contains the proposed table of contents, several articles on making UIs available, locating UI elements, custom control authoring and extensibility testing using UI Automation, and a list of performance profiling tools.
