Nice work! I translated to C# and change the property it's changing to RenderTransform.

static class DesignModeTool
{
    public static readonly DependencyProperty IsHiddenProperty =
        DependencyProperty.RegisterAttached("IsHidden",
            typeof(bool),
            typeof(DesignModeTool),
            new FrameworkPropertyMetadata(false,
                new PropertyChangedCallback(OnIsHiddenChanged)));

    public static void SetIsHidden(FrameworkElement element, bool value)
    {
        element.SetValue(IsHiddenProperty, value);
    }

    public static bool GetIsHidden(FrameworkElement element)
    {
        return (bool)element.GetValue(IsHiddenProperty);
    }

    private static void OnIsHiddenChanged(DependencyObject d,
                                          DependencyPropertyChangedEventArgs e)
    {
        if (!DesignerProperties.GetIsInDesignMode(d)) return;
        var element = (FrameworkElement)d;
        element.RenderTransform = (bool)e.NewValue
           ? new ScaleTransform(0, 0)
           : null;
    }
}
