Is it possible to show a shell only once all the modules have been loaded?

Question

I'm currently working on an application which uses PRISM 4 to divide its functionalities in different modules.

I noticed that my application's Shell, which holds the modules' views in its regions, is loaded and displayed before the modules are loaded.

This means that the Shell is displayed first, and a considerable amount of time later (about half a second), the modules are loaded and the views inserted into the Shell's regions. It's rather annoying, as the user is greeted with an empty shell at start-up, which isn't very professional.

Is there any way to detect when all the modules have been loaded ? Any method I can override in the bootstrapper ?

If I could, I would like to hide the Shell (or display a loading adorner) until all the modules have been loaded.

You can show your Shell view after Modules are initialized:

protected override void InitializeShell()
{
   Application.Current.MainWindow = (Window)Container.Resolve<ShellView>();
}

protected override void InitializeModules()
{
   base.InitializeModules();
   Application.Current.MainWindow.Show();
}
