Safe precise game loop in eto forms?

[Shadowblitz16]

How would I do a game loop in eto.forms?
The UITimer.Interval says its not a very precise timer.

    public class GameControl : Form
    {
        private UITimer   Timer    { get; } = new UITimer();

        public float      Delta    { get; private set; }
        public bool       Paused   { get;         set; }
        public Drawable   Drawable { get; } 


        public GameControl()
        {
            OnStart(Timer, EventArgs.Empty);

            Timer.Interval = 1.0 / 60.0;
            Timer.Elapsed += Elapsed;
            Timer.Start();

            OnEnd  (Timer, EventArgs.Empty);
        }

        void Elapsed(object sender, EventArgs e)
        {
            OnLoop?.Invoke(sender, e);
            Delta = Timer.ElapsedTime;
        }

        public event EventHandler OnStart;
        public event EventHandler OnLoop;
        public event EventHandler OnEnd;
    }
