Async call of ASMX web service

Question

In my scenario when ever user changes some fields in the program and does a SAVE , a webserivce request is sent to save some logging information into the database. I did some search on the website and found this solution for Async calls:

 ThreadPool.QueueUserWorkItem(delegate
 {
    // Create an instance of my webservice object.
    // call its Log webmethod.
 });

But since I don't have much experience with webservices and Async calls so I wanted to show you the scenario I have and the way I am handling it to get your opinion about it and if it the right way to do this. Thanks for suggestions.

Answer 1

Can you tolerate the logging work to be lost? Only then should you start "background work" in an ASP.NET app.

QueueUserWorkItem will work. The more modern version is Task.Run . Make sure you catch errors that happen on that thread-pool thread. If not, you'll never find out about bugs and silently lose work.

If you expect a high volume of such calls, or expect them to take a long time, consider using async IO . It does not use any thread while in progress (not even a background thread).
