What happens in the case of a wcf session that has created an asynchronous function (such as background automated emailing ) when the client closes session ie client.Close()/client.Abort()?

In otherwords if have some as below:

[OperationContract(IsOneWay = true, IsInitiating = true, IsTerminating = false)]
void RegisterUser(string user);

[OperationContract(IsOneWay = false, IsInitiating = false, IsTerminating = false)]
void SendEmails(T[] listofDetails);

[OperationContract(IsOneWay = false, IsInitiating = false, IsTerminating = true)]
void UnRegisterUser();

and SendEmails creates a task or async function (the async call isn't done client side) that sends off all the emails in the background. And the user Terminates the session before all the emails are finished sending? Does the session still stay open and wait or does it close and the emailing just keeps going until it finishes or what happens?

Thanks All
Sorry if the question is a bit ambiguous :/

在您的示例中，您定义了一个名为 SendEmails 的请求-响应操作，该操作返回 void。这与异步操作不同。

我假设您正在操作方法中创建一个新的后台线程，然后该线程会消失并发送电子邮件。

在这种情况下，一旦操作方法完成执行，操作将返回 void 给调用者。如果客户端随后终止通道，则后台线程将继续其工作。
