How to create an async WCF service

I want to implement a WCF service that responds immediately to the caller, but queues up an asynchronous job to be handled later. What is the best way to go about doing this? I've read the MSDN article on how to implement an asynchronous service operation, but that solution seems to still require the task to finish before responding to the caller.

There are many ways to accomplish this depending what you want to do and what technologies you are using (e.g. Unless you are using silverlight, you may not need to have your app call the service asynchronously) The most straight forward way to achieve your goal would be to have your service method start up a thread to perform the bulk of the processing and return immediately.

Another would be to create some kind of request (e.g. Create an entry in a datastore of some kind) and return. Another process (e.g. A windows service, etc.) could then pick up the request and perform the processing.

Any WCF service can be made asynchronous -

One of the nice things about WCF is you can write a service synchronously. When you add a ServiceReference in the client, you have the option of generating asynchronous methods.

This will automatically make the service call asynchronous. The service will return when it's done, but the client will get two methods - BeginXXX and EndXXX, as well as XXXAsync + an XXXCompleted event, either of which allows for completely asynchronous operation.
