How do you build line-of-business applications in Silverlight and Windows Presentation Foundation (WPF) that can be maintained and extended over a period of years? How do you design and code to handle real-world complexity? Composite Application Guidance (a.k.a., "PRISM") from patterns & practices offers guidance, libraries and examples--in small, free-standing, digestible chunks--that you can use to tame the complexity.

In this episode of ARCast.tv, I sit down and chat with Ward Bell to learn how to compose complex UIs from simpler views, integrate loosely coupled components with "EventAggregator" and "Commands", develop independent modules that can be loaded dynamically, and share code between Silverlight and WPF clients.
