WCF percall and single instance.
I used [this][1] example to implement WCF service that fires events (using callback) to all clients when something happening on the service.<br> The problem is that this example works only when the service instance is percall.

    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Reentrant)]
I want to use single instance but it won't work.<br>
Please help.
