One of the new features to Silverlight 3 is the ability to add multi-touch capabilities to your application.

Hopefully I’m stating the obvious here, but your hardware has to support multi-touch. And I’m not talking about that fake kind. I’m talking about hardware that announces the WM_TOUCH messages to Windows. If you (or your customers) aren’t going to be having multi-touch hardware, then writing against this API isn’t going to help! I’m currently using the HP TouchSmart TX2 laptop running Windows 7. I find this to be a good machine and fairly cheap-ish with regard to how laptops are these days and with the features it provides.

The first thing to understand is how to tap into the touch events from the hardware to Silverlight. Understanding this at the beginning of your application development can be a critical step. The key reason for this is unlike other input events (i.e., MouseLeftButtonDown, etc.) which can be added to individual UIElements in an application, the touch event is an application-wide event.
