invoke

To pop-up a message box, I'm using MessageBox.Show(...). I usually wrap this call in an Invoke:

BeginInvoke (new Action (() => {
    MessageBox.Show ());
}));

I've got 2 questions:

Do I always need to wrap the MessageBox call in an Invoke if I'm calling from a non-GUI thread?
If so, should I use BeginInvoke or Invoke? I found not much difference in my tests, BeginInvoke is, as expected (and unlike Invoke), displayed with a slight delay.
