changing the text of a label (or sophisticatedly we can say a text-based progress bar). in winforms you just Invalidate / Update.

Answer 1

    public static class ExtensionMethods
{

   private static Action EmptyDelegate = delegate() { };
 

   public static void Refresh(this UIElement uiElement)
   {
      uiElement.Dispatcher.Invoke(DispatcherPriority.Render, EmptyDelegate);
   }
}

private void LoopingMethod()
{
   for (int i = 0; i < 10; i++)
   {
      label1.Content = i.ToString();
      label1.Refresh();
      Thread.Sleep(500);
   }
}
