Question

I would like to detect if the user has their finger held on the screen when my app starts so that I can perform some different functionality.

Most of what I’ve seen is in regards to gestures but I don’t think that would work since the user will already have their finger held down when the app starts. It would be extra cool if I could detect how many fingers so that I could go directly to a different page for two fingers.

Thanks for any ideas.

The TouchFrameEventArgs that occurs provides a mechanism to query multiple touch points

In my post i only deal with primary touch ponit but the GetTouchPoints method will give you all touch points as a collection
