How to show messagebox on f1 keypress WPF c#

Question

I have a wpf window called MainMenuWindow. I want to show a MessageBox when the user presses F1 on their keyboard, no matter where they are on the window

private void Window_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key == Key.F1)
    {
        MessageBox.Show("Help");
    }
}

This is what I have so far.
But I don't know where to reference it or if it's even right. I know how to do it on winforms applications, but cant seem to get it working on wpf.

To specify events, you have to add a KeyDown entry to your Windowss xaml code:

<Window xClass="... 
        ...
        ...
        KeyDown="Window_KeyDown">
