Silverlight, WPF, and Windows Phone 7 developers should consider using the Model-View-ViewModel (MVVM) pattern for developing their LOB applications.  One choice for MVVM is Caliburn.Micro developed by Rob Eisenberg.

Here is a link to the documentation topics:

• Getting Started
  • Introduction
  • Obtain and Build the Code

• Soup to Nuts
  • Basic Configuration, Actions and Conventions
  • Customizing The Bootstrapper
  • All About Actions
  • WP7 Basics
  • Coroutines

• Recipes
  • SimpleContainer

I know Rob has been working on some WP7 goodness that should be out soon.  Looking forward to the release.
