What’s Caliburn?

Designed to aid in the development of WPF and Silverlight applications, Caliburn implements a variety of UI patterns for solving real-world problems. Patterns that are enabled by the framework include MVC, MVP, MVVM, Commands and Application Controller.

Goals– Support building WPF/SL application that are TDD friendly.– Implement functionality for simplifying various UI design patterns in

WPF/SL. These patterns include MVC, MVP, Presentation Model (MVVM), Commands, etc.

– Ease the use of a dependency injection container with WPF/SL.– Simplify or provide alternatives to common WPF/SL related tasks.– Provide solutions to common UI architecture problems.

Cons

• ViewModelen (or Presenter) can turn out to be the new place to dump code

• Black magic• Error messages• Resharper and Caliburn are not quite best
