Composite Application Guidance for WPF 2008 RC1 is now available for download. It has complete source code of the Composite Application Library and some quickstarts for you to get aquainted with this framework.
"The Composite Application Guidance for WPF is designed to help you more easily build enterprise-level Windows Presentation Foundation (WPF) client applications. This guidance will help you design and build flexible composite WPF client applications – applications that use loosely coupled, independently evolvable pieces that work together within the overall application.
This release is the first release of composite application guidance for WPF; based on your feedback, this guidance will evolve in future releases. It is marked as a release candidate as its final destintation is MSDN scheduled within a couple weeks. We don't expect the content to change before going to MSDN."
Available quickstarts:
Commanding
Event Aggregation
Hello World
Modularity
UI Composition
It also comes with the StockTrader Reference Implementation that uses Unity IoC for Dependency Injection as well as a sparse amount of the Enterprise Library Logging Application Block and Exception Handling Block for infrastrucutre services.
Even though the Composite Application Guidance for WPF comes out as a RC, it isn't expected to change before the final release.
