void Window1_PreviewStylusDown(object sender, StylusEventArgs e)
{
    IInputElement capturedElement = Stylus.Captured;

    if (capturedElement != null)
    {
        capturedElement.ReleaseStylusCapture();
    }
}

Private Sub Window1_PreviewStylusDown(ByVal sender As Object, ByVal e As StylusDownEventArgs) _
    Handles Me.PreviewStylusDown

    Dim capturedElement As IInputElement = Stylus.Captured

    If Not (capturedElement Is Nothing) Then
        capturedElement.ReleaseStylusCapture()
    End If

End Sub
