Question

I have web application with WCF service. That service contains method that implements message notification. The problem is that with big number of users it takes too much time and throws request timeout exception. What is the best way to solve this problem. Increasing time for request is not available, user won’t wait more than minute. Maybe multi-threading or async invocation of notification method will help? Or is there better solution?

Answer 1

If your notification method is not essential for the request to be serviced effectively, then move it to another thread.

As an architectural point you may consider moving all notifications to their own service, the API of which can then be consumed asynchronously.
See here for how.
