Simple threading question

In a service, the OnStart() method creates a couple threads. When the service is stopped, it looks like those threads continue to execute for a while.

Do these created threads continue to exist even after the thread that created them exits? What's the best way to clean up?

TIA,
Mike

not sure if will solve your problem , but set all threads isbackground property to true, this will make them terminate when all foreground threads terminate

Seems to do the trick, thanks.
