Silverlight.FX

Silverlight.FX is an application framework for building Rich Internet Applications with Silverlight 2. It focuses on providing building blocks and controls that allows applications to be naturally well-architected.

• Enable concise declarative specification of user interfaces. The driving philosophy is what is declarative and ought to be designable should remain declarative, without requiring significant amount of code-behind logic. Furthermore, the resulting XAML should not appear bloated.


• Enable easier separation of view and code. This is to facilitate separation of concerns, and promote testability and reusability.


• Provide a lean framework. The general approach is to favor composability over kitchen-sink style features. Silverlight.FX is currently ~60KB compressed, and the goal is to stay under 100KB as development progresses for its mainline functionality.
