Hello, I try to implement Splash Screnn in WPF. I have found some nice ehample in MSDN, but there is one place:
private void _applicationInitialize(SplashScreen splashWindow)
{
    Thread.Sleep(1000);
    // Create the main window, but on the UI thread.
    Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Invoker)delegate
    {
        Window1 MainWindow = new Window1();
        Helper.setWin(MainWindow);
        MainWindow.Show();
    });
}
The problem is Helper, whats the class is there and how it must be implemented. Someone could paste an example or smth?
