This deck was from TechEd 2006. The talk had the following abstract:

Learn how to use Windows Presentation Foundation application-level primitives for data management, system interaction, hosting, and UI to create great client applications. See how to create both standalone client applications and rich browser applications that can take advantage of these services. Gain knowledge that will help you make application-level decisions, such as when your application should be hosted in the browser or a standalone window, whether or not to write a navigation-based application, and how to manage application data and settings for various scenarios.
