Help Creating a Custom Splash Screen?...

Hi,

Need help trying to get my custom splash screen working based on this example from Channel 9 "Improving perceived WPF app startup performance with MEF and a Splash Screen".

I can't get any of the Storyboards to work nor display text in aTextBlock:

Creating the splash screen during InitializeModules() in my MefBootstrapper:

public class NatsarBootstrapper : MefBootstrapper
{
	#region Private Properties
	private IEventAggregator EventAggregator
	{
		get { return ServiceLocator.Current.GetInstance<IEventAggregator>(); }
	}
	#endregion

	protected override void InitializeModules()
	{
		IModuleManager manager = ServiceLocator.Current.GetInstance<IModuleManager>();

		Loading loading = this.Container.GetExportedValue<Loading>();
		Shell shellMain = this.Container.GetExportedValue<Shell>();

		loading.WindowStartupLocation = WindowStartupLocation.CenterScreen;
		loading.WindowState = WindowState.Normal;

		Application.Current.MainWindow = loading;
		Application.Current.MainWindow.Show();

		EventAggregator.GetEvent<MessageUpdateEvent>().Publish(new MessageUpdateEvent { Message = "Loading TurahStudyUIModule" });
		manager.LoadModule("TurahStudyUIModule");

		Application.Current.MainWindow.Hide();

		TurahStudyUIView view = ServiceLocator.Current.GetInstance<TurahStudyUIView>();

		shellMain.Height = 768;
		shellMain.Width = 1024;
		shellMain.WindowStartupLocation = WindowStartupLocation.CenterScreen;
		shellMain.WindowState = WindowState.Maximized;
		shellMain.Activate();

		Application.Current.MainWindow = shellMain;
		Application.Current.MainWindow.Content = view;
		Application.Current.MainWindow.Show();
	}

	protected override void ConfigureAggregateCatalog()
	{
		try
		{
			this.AggregateCatalog.Catalogs.Add(new AssemblyCatalog(typeof(NatsarBootstrapper).Assembly));
			this.AggregateCatalog.Catalogs.Add(new AssemblyCatalog(typeof(NatsarCommonModule).Assembly));
			this.AggregateCatalog.Catalogs.Add(new AssemblyCatalog(typeof(TurahStudyUIModule).Assembly));
		}
		catch (Exception msg)
		{
			.....
		}
	}

	protected override DependencyObject CreateShell()
	{
		DependencyObject shell = null;

		return shell;
	}
}

Loading.xaml.cs:

[Export(typeof(Loading))]
[PartCreationPolicy(CreationPolicy.NonShared)]
public partial class Loading : Window, IPartImportsSatisfiedNotification
{
	public Loading()
	{
		InitializeComponent();
	}

	[Import]
	public LoadingModel ViewModel
	{
		set
		{
			this.DataContext = value;
		}
		get
		{
			return DataContext as LoadingModel;
		}
	}

	/// <summary>
	/// Called when a part's imports have been satisfied and it is safe to use.
	/// </summary>
	public void OnImportsSatisfied()
	{
		// IPartImportsSatisfiedNotification is useful when you want to coordinate doing some work
		// with imported parts independent of when the UI is visible.
		Debug.WriteLine("Loading OnImportsSatisfied instantiation");
	}
}

LoadingModel.cs is where I'm just sending test text:

[Export(typeof(LoadingModel))]
[PartCreationPolicy(CreationPolicy.NonShared)]
public class LoadingModel : NotificationObject
{
	[ImportingConstructor]
	public LoadingModel(IEventAggregator eventAggregator)
	{
		Debug.WriteLine("LoadingModel instantiation");
		eventAggregator.GetEvent<MessageUpdateEvent>().Subscribe(e => UpdateMessage(e.Message));
	}

	private string _status;
	public string Status
	{
		get { return _status; }
		set
		{ 
			_status = value; 
			RaisePropertyChanged(() => this.Status); 
		}
	}

	private void UpdateMessage(string message)
	{
		if (string.IsNullOrEmpty(message))
		{
			return;
		}

		int maxRecords = 1000;
		for (int x = 1; x < maxRecords; x++)
		{
			System.Threading.Thread.Sleep(10);
			Status = string.Format("{0}: {1} {2}",message ,Convert.ToInt32( ((decimal)x / (decimal)maxRecords) * 100), "...");
		}
	}
}

Code is like a box of chocolates!...
