I\'m using a System.Timers.Timer and I\'ve got code like the following in my OnStart method in a c# windows service.

Answer 1

Just start a threadpool thread to call the worker function, just like Timer does. Like this:

        timer.Elapsed += timer_Elapsed;
        ThreadPool.QueueUserWorkItem((_) => DoWork());
    ...

    void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) {
        DoWork();
    }

    void DoWork() {
        // etc...
    }
