title: Event upon initialization complete in WPF/Prism app
body: <p>In non-Prism WPF app, if I want to run code after initialization (e.g. execute the task specified by command-line argument), I can do it in <code>Loaded</code> event of the main window. However with Prism, the modules are initialized after main window is displayed, that is, <code>IModule.Initialize()</code> is called after <code>Bootstrapper.CreateShell()</code> and <code>Bootstrapper.InitializeShell()</code>. In this case which event/override should I use?</p>
