WCF client not working after add a customer binding endpoint to the same ServiceHost

Question

1. extend WCF stuff hosting a NamedPipeServerStream to support communication with nodejs, it works if open a new ServerHost with endpoint "net.jsonpipe://localhost/JasonService".
2. a workable ServerHost with endpoint "net.pipe://localhost/MyService", everything is fine with a proxy , c# client DuplexClientBase.
3. once i open these two endpoints in one ServerHost, the c# client not working any more. with WCF TRACE, i see an exception There was an error reading from the pipe: The pipe has been ended. (109, 0x6d) when TransportSend.

anyone has any clue for help?

thanks in advance

Please turn on Trace for detailed error information in this case to locate the cause. You can view the following links on how to configure Trace here:

The problem could be a serialization issue or it could be related to the transport mode(try changing the transfer mode from buffered to streamed).

You can check this post to find the solution.
