How do I change localization in C# on Windows Phone?

I have my Resource files with 2 languages and my app already reads the values of one of them. I would like to be able to change the language of my app (use the other resource file) in C# instead of changing the language of the whole phone in Settings.

Is this possible? If so, how?

you can do this without need to restart by reloading the page where the user change a language and maintaining the RTL/LTR of your page layout

I added this function in App.xaml.cs 

public static void ChangeAppLanguage(string CultureName)
    {
        App.RootFrame.Language = XmlLanguage.GetLanguage(CultureName);
        FlowDirection flow = (FlowDirection)Enum.Parse(typeof(FlowDirection), AppResources.ResourceFlowDirection);
        App.RootFrame.FlowDirection = flow;
        App.Current.RootVisual.UpdateLayout();
        App.RootFrame.UpdateLayout();
        var ReloadUri =( App.RootFrame.Content as PhoneApplicationPage).NavigationService.CurrentSource;
        (Application.Current.RootVisual as PhoneApplicationFrame).Navigate(new Uri(ReloadUri + "?no-cache=" + Guid.NewGuid(), UriKind.Relative));
    }

where the CultureName like this : "ar-SA", "en-US"

and I called like this

private void EnglishMenuItem_Click(object sender, EventArgs e)
    {            
        try
        {
            if(Thread.CurrentThread.CurrentCulture.Name == "en-US")
                Thread.CurrentThread.CurrentCulture = new CultureInfo("ar-SA");
            else
                Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
            Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

            AppResources.Culture = Thread.CurrentThread.CurrentCulture;

            App.ChangeAppLanguage(Thread.CurrentThread.CurrentCulture.Name);

            //this._contentLoaded = false; //this way does not refresh appBar
            //this.InitializeComponent();

            //this way work for one time only => if user change language more thane once the api does NOT call constructor
            //NavigationService.Navigate(new System.Uri("/PhoneApp2;component/MainPage.xaml", System.UriKind.Relative));

        }
        catch (Exception ex)
        {
            MessageBox.Show("error:\n\n" + ex.Message);
        }
    }

In App.xaml.cs, in the InitializePhoneApplication method:

private void InitializePhoneApplication()
{
    Thread.CurrentThread.CurrentCulture = new CultureInfo("fr-FR");
    Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
    .......
}

The limitation is that it needs to be in the app initialization, so if the user changes the language, a restart will be required for it to take effect.
