In this session, we cover what Microsoft Silverlight is and explain how you can capitalize on its capabilities to easily create browser-based applications. Join us to see the powerful media and graphics capabilities Silverlight offers, and the compelling Web sites that have been created with it. Silverlight also has strong data capabilities, making it attractive for building line-of-business (LOB) applications. In this first of two sessions on building a Twitter application in Silverlight 3, we provide a quick overview of the Silverlight platform and then get hands on by putting together an application that consumes server-side data and contains some simple navigation.
