阻塞线程直到 WCF 回调被引发？

Question

Is it possible to wait on a callback in WCF? Giventhis article, I will raise a callback in my WCF service, but I want the client (a seperate application) to only proceed (ie go to the next line of code, eg close a form etc, after the callback is raised. So I need to block until the callback is raised.

How could I do this?

Answer 1

Instead of using callbacks, you could call the service synchronously from the client.

If the client does not require any data to be returned, you could return a void, and the client will still wait for the call to complete.
