Windows 7 WPF Touch API

While WPF developers are waiting for WPF 4.0 to come out with multitouch support, there is a stop gap solution of sorts. MSDN has an open source library that maps touch events to stylus events (e.g. StylusDown --> TouchDownHandler ) and includes a gesture engine with gesture events like pinch, pan, zoom, rotate, and two finger tap.

This library allows you to write WPF applications that can process touch input. I suspect, although I don't know, that this library is just a temporary solution that will become absorbed or abandoned when WPF 4.0 is finally released. That said, a stop-gap solution is better than no solution at this point.
