This document provides an overview and summary of Silverlight 4 frameworks, patterns, and capabilities. It discusses ASP.NET client application services, WCF data services, WCF RIA services, navigation, search, extensible applications using MEF, and the MVVM pattern. The document includes several demos that could be shown to illustrate these topics. It also provides information on related sessions at the conference to learn more.
