Client App Dev MVP Jason Rainwater has recently released his Razre Framework on CodePlex. This is a WPF Application Framework intended to provide base functionality for creating robust WPF applications. This project will be on-going adding new features and enhancements.

The current version of the framework includes the following functionality:

• An implementation of the Model-View-ViewModel design pattern.
• Utilizes Un-Keyed DataTemplates to resolve a View for a ViewModel
• Integrated into the Theming mechanism to provide performant Theming 
• Main Region Navigation
• Allows the ability to define a ContentControl for the Main Navigation region
• Provides the ability to define a custom transition animation to be used when Navigating
• Full Layout Theming
• Provides the ability to define Theme dictionaries and load them
• Integrated into the MVVM implementation to notify ViewModels to swap their visual representation.

The framework makes use of Microsoft’s Composite Application Guidance (Prism 2) to help support integral systems.
