Changing ApplicationBar Icons for Theme Awareness

Its quite a punch in the face for WP7 developers,but i'll give you a hand here.

If you have light and dark sets of your icon,you can make it work by writing these codes on your Loaded event of PhoneApplication Page:

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)         {             var visibility = (Visibility)Application.Current.Resources["PhoneLightThemeVisibility"];             if (visibility == Visibility.Visible)             {                                   var button = (IApplicationBarIconButton)ApplicationBar.Buttons[1];                 button.IconUri=new Uri("H_light.png",UriKind.Relative);             }               else             {                 var button = (IApplicationBarIconButton)ApplicationBar.Buttons[1];                 button.IconUri = new Uri("H_dark.png", UriKind.Relative);             }         }

So after building and running the project,it'll be working like a charm.

Hope it helps!
