The web was built using dynamic languages. Their plain-text format made it easy to mash up scripts to create the next great app. Similarly, dynamic languages will find a home in Silverlight applications where plain-text formats are common. Silverlight can be easily deployed, which means that a wider range of dynamic languages will be used in building browser-hosted applications. In this demo-centric talk, you will see this happen before your eyes as we rapidly create an application by combining code and markup from existing samples in Ruby, Python, JavaScript, and Visual Basic. This unprecedented level of integration is possible since all of these languages are implemented on top of the new Dynamic Language Runtime (DLR).
