Building Loosely Coupled Silverlight Business Applications

With Silverlight 4 and .NET 4, there is a great mix of capabilities that you can leverage to build N-Tier Silverlight business applications. WCF RIA Services allows you to quickly write server side logic and data access and expose that to the Silverlight client through an easy programming model. The Managed Extensibility Framework allows you to glue together parts of your application without needing a bunch of explicit code to connect the different parts your application is composed of. And the Model-View-ViewModel pattern provides a way to structure your presentation layer to minimize coupling, making it easier for designers and developers to work independently and making your presentation logic more testable. In this talk, you’ll see how to tie all these capabilities together into a coherent whole. You’ll get a quick intro to WCF RIA Services and MEF and what they can do, and then you will see how to use them all together in an application to benefit from the high productivity of WCF RIA Services but still maintain a clean, loosely coupled architecture.
