En el ejemplo siguiente se muestra cómo configurar un InkCanvas para reconocer gestos de aplicación.

// Add this code to the contstructor or OnLoaded method.
if (inkCanvas1.IsGestureRecognizerAvailable)
{
    inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture;
    inkCanvas1.Gesture += new InkCanvasGestureEventHandler(inkCanvas1_Gesture);
    inkCanvas1.SetEnabledGestures(new ApplicationGesture[] 
                    {ApplicationGesture.Down, 
                     ApplicationGesture.ArrowDown,
                     ApplicationGesture.Circle});
}

' Add this code to the contstructor or OnLoaded method.
If (inkCanvas1.IsGestureRecognizerAvailable) Then

    inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture

    Dim gestures() As ApplicationGesture = _
                        {ApplicationGesture.Down, _
                         ApplicationGesture.ArrowDown, _
                         ApplicationGesture.Circle}

    inkCanvas1.SetEnabledGestures(gestures)
End If

void inkCanvas1_Gesture(object sender, InkCanvasGestureEventArgs e)
{
    ReadOnlyCollection<GestureRecognitionResult> gestureResults = 
        e.GetGestureRecognitionResults();

    // Check the first recognition result for a gesture.
    if (gestureResults[0].RecognitionConfidence == 
        RecognitionConfidence.Strong)
    {
        switch (gestureResults[0].ApplicationGesture)

                // Do something.
                break;
        }

        Select Case gestureResults(0).ApplicationGesture
            Case ApplicationGesture.Down
