How to avoid timeouts in WCF?
- by Jader Dias
I use netNamedPipeBinding, and my service methods return nothing (void), but they timeout:
TimeoutException: "The open operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout."
Server stack trace:

at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
To avoid this I turned my service into a OneWay operation. But the timeout still occurs. I expected that it solved my problem. Its the netMsmqBinding the only one that could avoid such timeout?
I also tried to make all processing in a separate thread, so the service can disconnect earlier, with no success.
