This turns out to be really important. Otherwise the modal dialog doesn't stay on top of the application's window stack, which can make things awkward when ShowInTaskbar is set to false. The easiest way to ensure this is getting done is to make it part of the constructor arguments. The code now passes the parent window in explicitly. WPF MessageBox avoids this by calling UnsafeNativeMethods.GetActiveWindow(), but that feels weird. We could assume Application.Current.MainWindow is the parent, but that seems like it could go quietly and horribly wrong.
