WPF Multitouch - How to get all the breakpoints?

We rate touch keyboards, and for one we need to track 10 fingers at a time. The problem is that the touch screen driver is very warlike (and there is no fixed version). It sends 2500+ events for an event FrameReportedevery second for as many fingers. There is no way to deal with all these problems, even if we drop 90% at the beginning. It is simply impossible to maintain and do anything meaningful with data.

Instead, System.Windows.Input.Touch.FrameReportedI also tried to use events (Preview) TouchMovein the window; Here is the problem.

So, now I wanted, instead of using events, to poll a separate thread, but I can not find information on how to get all the current touch points.

The only thing I found was to hack WinForms, but this is not an option, since then I will not be able to display any WPF controls in my window.

Any solutions?

Edit 1:

This is the code that handles all move events:

private void UserControlTouchMove(object sender, TouchEventArgs e)
{

        //Update Position of the corresponding point
    var touch = e.GetTouchPoint(this);
    var id = touch.TouchDevice.Id;
    e.Handled = true;
    var position = touch.Position;
    //update finger on display, quick and dirty
    if (m_ShowFingers)
    {
        foreach (var finger in m_Fingers)
        {
            if (id == (int)finger.DataContext)
            {
                finger.RenderTransform = new TranslateTransform(position.X - HalfFingerSize, position.Y - HalfFingerSize);
                break;
            }
        }
    }
}
