Having to add this to pages that host panoramas to work around this bug - https://connect.microsoft.com/VisualStudio/feedback/details/772715/wp8-panorama-using-itemssource-does-not-keep-track-of-selectedindex - what's the point of data binding if it's not universal? Basically you can't databind a panorama control in WP8 and expect it to work - 7…

PanoramaHandling

public void WirePanorama(ObservableCollection<Screen> topNavItems)
{
  Dispatcher.BeginInvoke(() =>
		{
			Panorama.Items.Clear();

			foreach (var pi in topNavItems.Select(CreatePanoramaItemForViewModel))
			{
				Panorama.Items.Add(pi);
			}
		});
}

private static PanoramaItem CreatePanoramaItemForViewModel(Screen screen)
{
	return new PanoramaItem
		{
			Header = new TextBlock()
					{
						Text = screen.DisplayName,
						FontSize = 72,
						FontWeight = FontWeights.ExtraLight,
						Foreground = new SolidColorBrush((Color) Application.Current.Resources["PhoneAccentColor"])
					},
			Content = CreateControlForViewModel(screen)
		};
}

private static object CreateControlForViewModel(Screen screen)
{
	var c = ViewLocator.LocateForModelType(screen.GetType(), null, null);
	ViewModelBinder.Bind(screen, c, null);
	return c;
}

Looks like very powerful code. I am also very interested in some UI panorama, and I recently got a panorama control tutorial, but not quite understand the .NET environment.
