Granular is a re-implementation of WPF which is designed to run in the browser, it aims to bring to web applications the same development experience as WPF brings to desktop applications (with xamls, code-behind, real MVVM).

Using Saltarelle C# to JavaScript compiler, Granular fills the gap between a simple JavaScript "Console Application" and a full "WPF Application".

GranularPad is a good showcase of the current Granular framework capabilities (don't forget to inspect the visual tree in the DOM :)

Granular can be separated into two parts:

• Presentation - Maintains a visual tree (with dependency properties, routed events, animations and so on) which is completely separated from its host, exactly the same way as WPF does.
• Host - Contains a minimal rendering engine and a raw events source, the Presentation part interacts with the Host the same way as WPF interacts with MilCore (DirectX adapter) and WndProc messages.

Granular aims to seamlessly replace WPF so that Granular applications could be created in addition to existing WPF applications, share the same source code, and deploy to a different environment.

In addition to a browser, Granular can also be hosted in a desktop application, so that verifying compatibility with WPF could be easily done with Visual Studio.
