Arguably the most innovative and forward thinking feature of Windows 7 is its multi-touch support. And it should be no surprise to see that Windows Presentation Foundation (WPF) 4 boasts the same multi-touch support that utilizes this Windows 7 multi-touch support where available. In this session we explore this new feature in WPF 4 and see what we get for free (i.e.,without having to do any work),what you can get with only minimal additional work and what takes a bit more time and effort. Along the way we discover the basic touch support together with support for rotation,scaling and inertia as well as how to handle low level touch events using the raw API. Please note: The presentation shows true multi-touch – this is not a trick with two mice simulating multi-touch.
