Wcf Request Lifecycle

Question

Is there a lifecycle that WCF requests go through? Specifically I need to be able to intercept and possibly cancel requests made before they get to the method that was invoked.

Answer 1

You need to implement an IDispatchMessageInspector and inject it in the serivce behavior stack.

use IDispatchMessageInspector.AfterReceiveRequest to accept or reject a request.
