Just a caveat, I do not have a multitouch Windows 8 device to test this code on. In the case of multiple devices or multi-touch input, each contact is treated as a unique pointer. The system creates a pointer when a contact is first detected and destroys it when the pointer leaves (departs) detection range or is canceled. The documentation with working example code resides in the MSDN LibraryĪ pointer object represents a single, unique input 'contact' (a PointerPoint) from an input device (such as a mouse, pen/stylus, single finger, or multiple fingers). According to this MSDN Forum Posting you will need to use pointer notifications.
