Silverlight 4: Any touch library that supports gestures & touch events?

Silverli开发者_JAVA百科ght provides only Touch.FrameReported event and doesnt provide any events for the UIElements like it does for mouse events(ex: MouseDown, MouseUp). Is there any touch library available for the silverlight which provides these touch events and supports gestures.

Google did not help me much or may be my search terms are not correct. Any pointers will be appreciated.

Here is some useful stuff, but it is nowhere near a complete library:
