C# - How do I invoke a method on a different thread from a Timer's Elapsed event?

I have a System.Timers.Timer object, and within its Elapsed method I want to call myObject.TriggerEvent(...), but I want that invocation to happen on the thread myObject was created on. Is there an easy way to do this? And is this a bad idea for any reason? myObject is basically an event manager service, so I want it to trigger events on the thread it was created on. The reason I'm using the timer is because I have another that is polling a service for updates, which it notifies myObject of via the TriggerEvent method.

I would recommend using a Dispatcher. It was created in the context of WPF, but there is no reason it can't be used elsewhere. I've used it in a couple of times, but I always had a message pump (Win32), but I believe that it can be used in service contexts as well (IIS, etc) - however I have not written such code, so YMMV. This is a good article from a WPF angle.

You can make your own SynchronizationContext implementation and provide its instance to the caller of myObject.TriggerEvent. If you're using myObject in WPF, SL or WinForms application, you can use their existing implementations of SynchronizationContext class and create myObject on the GUI thread.
