WPF MenuItems

For some reason my menu items expand towards the left instead of to the right. No other apps on my device do it like this so I don't think its a system setting. Any ideas on how I can fix this?

Okay nevermind, for some reason Windows thinks right-handed people get this ^ and left handed people get menu items that are correctly aligned for WPF apps.

This is a solution I found on stackoverflow in case anyone is curious:

private static void SetDropDownMenuToBeRightAligned() {
            var menuDropAlignmentField = typeof(SystemParameters).GetField("_menuDropAlignment", BindingFlags.NonPublic | BindingFlags.Static);
            Action setAlignmentValue = () =>
            {
                if (SystemParameters.MenuDropAlignment && menuDropAlignmentField != null) menuDropAlignmentField.SetValue(null, false);
            };

            setAlignmentValue();

            SystemParameters.StaticPropertyChanged += (sender, e) =>
            {
                setAlignmentValue();
            };
        }

private static void SetDropDownMenuToBeRightAligned() {
            var menuDropAlignmentField = typeof(SystemParameters).GetField("_menuDropAlignment", BindingFlags.NonPublic | BindingFlags.Static);
            Action setAlignmentValue = () =>
            {
                if (SystemParameters.MenuDropAlignment && menuDropAlignmentField != null) menuDropAlignmentField.SetValue(null, false);
            };

            setAlignmentValue();

            SystemParameters.StaticPropertyChanged += (sender, e) =>
            {
                setAlignmentValue();
            };
        }

private static void SetDropDownMenuToBeRightAligned() { var menuDropAlignmentField = typeof(SystemParameters).GetField("_menuDropAlignment", BindingFlags.NonPublic | BindingFlags.Static); Action setAlignmentValue = () => { if (SystemParameters.MenuDropAlignment && menuDropAlignmentField != null) menuDropAlignmentField.SetValue(null, false); }; setAlignmentValue(); SystemParameters.StaticPropertyChanged += (sender, e) => { setAlignmentValue(); }; }
