Remarks

Touch input requires hardware that is touch-sensitive and an environment that supports the infrastructure that exposes touch events to individual applications. For more information, see Touch Input in Silverlight.

Version Notes

Silverlight for Windows Phone uses an entirely different touch input model. For more information on touch input, manipulations and gestures for Silverlight for Windows Phone, see How to: Handle Manipulation Events.
