Borrowing the content from Karl’s original blog post – there’s a new book on Prism available from O’Reilly or Amazon with an eBook on its way and the MSDN materials here
What’s In The Book?
Prism helps you to design and build flexible and maintainable WPF and Silverlight applications by using design patterns that support important architectural design principles, such as separation of concerns and loose coupling.
This guide will show you how to use Prism to implement the Model-View-ViewModel (MVVM) pattern in your applications, and how to use it along with commands and interaction requests to encapsulate application logic and make it testable.
It will show you how to split an application into separate functional modules that can communicate through loosely coupled events, and how to integrate those modules into the overall application.
It will show you how to dynamically construct a flexible user interface by using regions, and how to implement rich navigation across a modular application.
