Force UI update on the fly, after changing current culture in WPF

Question

I need to support UI language change through the application menu. The texts are localized using resource files (similar to approach 1 here)

if I set the Thread.Cu

Answer 1

A way that I tried and works well is this method, to call after the assignment of the property in the ViewModel:

private void AllowUiToUpdate()
{
    var frame = new DispatcherFrame();

    var dispatcherOperationCallback = new DispatcherOperationCallback(delegate
        {
            frame.Continue = false;
            return null;
        });

    Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Render, dispatcherOperationCallback, null);

    Dispatcher.PushFrame(frame);
}
