Puzzling Timer behaviour

Can I use a Timer in a .Net Windows Service that I create?

Like, you can't use an interface (you can if you're tricky), but is a timer okay?

My On_Start Event is empty because I have a timer that is suppose to fire every minute, but it doesn't, and I've NFI why. :confused:

Enabled is True and interval is 60000.

There are no errors in the event log. Nothing happens. I know it doesn't fire because I write to the event log in timer tick event so I'll know when it fires. It just doesn't fire.

Are Timers allowed in an NT Service? I thought they would be integral considering the nature of services.

Use System.Timers.Timer not System.Windows.Forms.Timer
