Vista - Positioning an app based on NavigationWindow

Is it possible to set the startup location of a NavigationWindow?

I tried setting it inside the App constructor like so:
this.MainWindow.WindowStartupLocation = WindowStartupLocation.CenterScreen;

but at this point MainWindow is null.

There doesn't appear to be any way of doing it (or I'm overlooking the
obvious!)

Thanks

You can set the WindowStartupLocation property for the navigation window in
the constructor of the navigation window (or in the XAML defining it). The
only exception is when the window is hosted in a browser, then you cannot
set the property.
