Answer 1

With .NET 4.5 you can also create an async delegate for your timer if you need to use the new .NET 4.5 await functionality.

        var timer = new DispatcherTimer();
        timer.Interval = TimeSpan.FromSeconds(20);
        timer.Tick += new EventHandler(async (object s, EventArgs a) =>
        {
            Message = "Updating...";
            await UpdateSystemStatus(false);  
            Message = "Last updated " + DateTime.Now;              
        });
        timer.Start();
