SessionEndingEvent not getting called

Question

this is my C# code:

    void main()
    {
        SystemEvents.SessionEnding += new SessionEndingEventHandler(SystemEvents_SessionEnding);
    }

    void SystemEvents_SessionEnding(object sender, SessionEndingEventArgs e)
    {
        Console.WriteLine(e.Reason);
    }

Somehow, there is no output. Any ideas why?
