Windows Phone multi-touch

Question

I would like to create in my Windows Phone Silverlight application two controls and start my timer when both of them are pressed. I tried to do this with MouseLeftButtonDown event, but it does not support multitouch. Tap event is fired after control is released so it is not what I want. Hold event is fired after one second after control is pressed - I would like to get event immediately when both controls are pressed in the same time.

How can I achieve that?

Thank you @Fabian . I used TouchPoint

I did something like this and it works:

TouchPoint primaryTouchPoint = e.GetPrimaryTouchPoint(mainGrid);
TouchPointCollection touchPoints = e.GetTouchPoints(mainGrid);

foreach (TouchPoint tp in touchPoints)
{
    var controlPosition = myControl.TransformToVisual(Application.Current.RootVisual).Transform(new Point(0, 0));
    if (tp.Action == TouchAction.Down && tp_is_in_myControl)
        do_something;

}
