Workflow Services Duplex Binding
Is Duplex Binding supported in windows Workflow Services and WCF in开发者_开发问答tegration? Can an activity "register" with a WCF service and then can a WCF service raise an event to the registered activity in the workflow when it needs to?
I just came across this and though it would help you out.
