An AsyncCallback threw an exception

Hey!

I've built a service with AsyncCallback (via http with WSHttpBinding).
I want to do exact the same thing with tcp and NetTcpBinding but I'm getting an exception:
"An AsyncCallback threw an exception"

Is this possible or is that just a bug in January CTP

Thanks.

    Hey!

    In my console application I put the async callback in a loop. If I have 10 iterations it works but when I change it to 20 or more I get this:

    "Could not connect to net.tcp://localhost:8000/asyncTcp. Tcp error 10061: No connection could be made because the target machine actively refused it."

    Why do I get this error
    Thanks.

    I think you're hitting a 10 connection limit in XP.

  • RyanSmith

    It seems that the problem only occurs in a windows application.
    I tryed the same thing in a console application and it works fine.

    Any ideas

    Thanks, John.
    Apparently it was the 10 connections limitation (xp pro).
