How do I listen to an event on an object from within a WCF web service?

I have a web service that instantiates an object, subscribes to an event on that object, and then calls a function on the object which will lead to the event being fired. Is there a way to wait for the event to fire so I can get the results from the EventArgs in order to pass those results as the results of the web service?

You will need some kind of synchronization primitive associated with the event (such as a ManualResetEventSlim) that gets signalled in the event handler. Then your request thread can wait on the event and collect the results after the event has occurred and generate the response

However, a more natural model may be to create the service as an asynchronous service and only complete the processing when the async operation completes - I created a sample of this a while back
