Dialog to mainframe data transfer (WPF)

Question

I have the problem with data transfer - i have a wpf application with a splash screen which is runs in App class before main frame is loaded. This Splash is a dialog and App is a static class - how is it possible to pass the data from splash dialog to mainframe maybe via App.. or there is other way?

An event could pass the data about.

public App : Application
{
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            var splash = new Splash();
            var main = new Main();

            splash.SplashViewFinished += (s, data) => {
                main.Data = data;

                //code to show main..
            };

            //code to show splash...
        }
}

public class Splash : Window
{
    public event EventHandler<SplashDataArgs> SplashViewFinished;
}

public class SplashDataArgs: EventArgs
{

}

Or you could use the mediator pattern. Like the Messenger class in MVVM light
