>Hi,

>I'm workingf on a WPF application using the MS CAL (Prism) library. Here's the Application.StartUp override:

public partial class App : Application
>    {
>        protected override void OnStartup(StartupEventArgs e)
>        {
>            LoginWindow l = new LoginWindow();
>            Nullable<bool> dialogResult = l.ShowDialog();
>
>            base.OnStartup(e);
>
>            BootStrapper bootStrapper = new BootStrapper();
>            bootStrapper.Run();
>
>        }

*Without* the LoginWindow dialog the BootStrapper (the usual - based on UnityBootStrapper) fires up fine. With the LoginWindow code in place it goes through the same process without error but when the Application.OnStartup exits the whole app exits. If I place the LoginWindow code *after* the bootStrapper.Run() line everything works fine (but I don't want to have the Shell displayed before the log in stuff has completed).
