Question

We have a WCF publish-subscribe model application, It works fine.

But this part of the code.

  foreach (SubList subscriber in subscribers.ToList())
        {
           try
             {
               object ClientResult;
               ClientResult = publishMethodInfo.Invoke(subscriber.CallBackId, new object[] { ClData });
                }
          }

Is there any way I invoke all subscribers all at once. As the above code is in a loop fetching each subscriber and publishing. This is causing other subscribers to wait until prior is executed.

Answer 1

Why not invoke them in parallel?

Parallel.ForEach(subscribers.ToArray(), subscriber =>
{
    try
    {
        object ClientResult;
        ClientResult = publishMethodInfo.Invoke(
            subscriber.CallBackId, new object[] { ClData });
    }
    ...
});
