.NET Windows Service needs to use STAThread

Question

I have created a Windows Service that will be calling out to some COM components, so I tagged [STAThread] to the Main function. However, when the timer fires, it reports MTA and the COM calls fail. How can I fix this?

using System;
using System.Diagnostics;
using System.ServiceProcess;
using System.Threading;
using System.Timers;



namespace MyMonitorService
{
    public class MyMonitor : ServiceBase
    {
        #region Members
        private System.Timers.Timer timer = new System.Timers.Timer();
        #endregion

        #region Construction
        public MyMonitor ()
        {
            this.timer.Interval = 10000; // set for 10 seconds
            this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.timer_Elapsed);
        }
        #endregion

        private void timer_Elapsed (object sender, ElapsedEventArgs e)
        {
            EventLog.WriteEntry("MyMonitor", String.Format("Thread Model: {0}", Thread.CurrentThread.GetApartmentState().ToString()), EventLogEntryType.Information);
        }

        #region Service Start/Stop
        [STAThread]
        public static void Main ()
        {
            ServiceBase.Run(new MyMonitor());
        }

        protected override void OnStart (string[] args)
        {
            EventLog.WriteEntry("MyMonitor", "My Monitor Service Started", EventLogEntryType.Information);
            this.timer.Enabled = true;
        }

        protected override void OnStop ()
        {
            EventLog.WriteEntry("MyMonitor", "My Monitor Service Stopped", EventLogEntryType.Information);
            this.timer.Enabled = false;
        }
        #endregion
    }
}
