This document discusses the differences between Silverlight and WPF and how WPF provides richer capabilities beyond Silverlight. It summarizes that WPF supports a broader range of media formats and controls, a more flexible developer model and security sandbox, and can be deployed to desktop applications, XBAP files, or via ClickOnce. It also outlines tools for WPF like Visual Studio and Expression Blend and the deployment of the WPF runtime.
