There are multiple possibilities to call an Operation Asynchronous from a WCF Service:<\/p>\n
In this model, you register to a Example:<\/p>\n <\/p>\n In this model, you call your Operation with a prepending Example:<\/p>\n <\/p>\n This is the only “true” Asynchronous Model. It will run in a Server-Thread so you are able to get the status of a pending Operation or even cancel it. The implementation is more time-consuming than the other two but, in some cases, worth the effort. <\/p>\n There is a very good series of posts at Dan Rigsby’s Blog<\/a> There are multiple possibilities to call an Operation Asynchronous from a WCF Service: Event Based Model In this model, you register to a Completed-Event and call your Operation with an Async appended.
