Simulate Fire & Forget scenario using C# Threading

Question

I have a web service, which takes lot of time to execute. I am planning to delegate the processing task to a background thread & return the acknowledgement response to the user immediately.

In this case I was worried about the life-time of the background thread.
Will background thread complete the delegated task, before main method/thread finishes execution?

"web service method must have returned the value" , which value? the value from your background thread? You said ur background thread will run a BIG task, why you want to wait for its finishing? — ValidfroM, Jul 31 '13 at 10:55
Or alternatively, just implement an asynchronous call, which is more simple IMO — ValidfroM, Jul 31 '13 at 11:03

Looks like your background thread might get aborted if the app pool gets recycled. Have a look at this article ThreadPool.QueueUserWorkItem in Web Service for “Fire and Forget” task

You should call your service asynchronously.

var service = new YouServiceClient();
service.SomeMethodCompleted +=
  (sender, args) +=
  {
    //  Put code here to handle the response and extract a return value or whatever.
  }
service.SomeMethodAsync();

Refer to How to: Call WCF Service Operations Asynchronously for more details.
