Consider wrapping this in try/catch due to async void.

(Same for the other two templates.)

Any suggestions on what to do if an Exception got caught? I basically copied this approach from the Wpf.Ui.Demo.Mvvm project and I'm not sure what else we can do when application initialization and startup fail.
We could call Environment.Exit(1)?

You're right, there's not much that can be done.
I believe not catching it will in this case just send the exception to Windows' Event Log, so the user may be confused why the app is just gone. IMHO, you should present the exception in a plain MessageBox, so it's at least clear that a crash occurred. (WinForms has a built in exception dialog, but I believe WPF does not.)
