In the following example, an event handler for the Started event checks to see if inertia processing is running and if so, stops it.

#region OnManipulationStarted
private void OnManipulationStarted(object sender, Manipulation2DStartedEventArgs e)
{
    if (inertiaProcessor.IsRunning)
    {
        inertiaProcessor.Complete(Timestamp);
    }
}
#endregion

#region Timestamp
private long Timestamp
{
    get
    {
        // Get timestamp in 100-nanosecond units.
        double nanosecondsPerTick = 1000000000.0 / System.Diagnostics.Stopwatch.Frequency;
        return (long)(System.Diagnostics.Stopwatch.GetTimestamp() / nanosecondsPerTick / 100.0);
    }
}
