    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);

        Dispatcher threadDispacher = null;
        Thread thread = new Thread((ThreadStart)delegate
        {
            threadDispacher = Dispatcher.CurrentDispatcher;
            SynchronizationContext.SetSynchronizationContext(new DispatcherSynchronizationContext(threadDispacher));

            loadingWindow = new LoadingWindow();
            loadingWindow.Closed += (s, ev) => threadDispacher.BeginInvokeShutdown(DispatcherPriority.Background);
            loadingWindow.Show();

            System.Windows.Threading.Dispatcher.Run();
        });

        thread.SetApartmentState(ApartmentState.STA);
        thread.IsBackground = true;
        thread.Start();

        var bootstrapper = new Bootstrapper();
        bootstrapper.Run();

        if (threadDispacher != null)
        {
            threadDispacher.BeginInvoke(new Action(delegate { loadingWindow.Close(); }));
        }
    }
