input: [Category] Concurrency Management [Description] WCF offers a the client a facility for dispatching calls to the service asynchronously. This is strictly a client-side feature, and the service itself is completely unaware that it is being called asynchronously. The client obviously needs a way to be notified when the calls complete and be able to harvest returned values or catch exceptions. All that is doe using a simple directive to SvcUtil: the /asyc switch that generates an asynchronous proxy. The download contains a sample asynchronous and synchronous proxy and a matching client, that uses a complete method to be notified when the call returns. [Last Updated] 7/30/2007 [Title]
