Are you a customer? The Design Pattern Framework contains a solution named Patterns in Action. It consists of a full featured implementation of several design patterns within a complete multi-layered application.
You will find a working example of how to implement different UI presentations (Winform, WPF, ASP.NET) on top of the same hosting-/business-/service-/data-layers.
I never saw a better and more complete example than this one.
Worth every dollar I spent on it. ;-)
