The problem I am experiencing is that if I leave my WCF service host running idly for a period (beyond the binding receive timeout?) then I find that subsequent method invocations from the client can result in a stream of "CommunicationException" , "CommunicationObjectAbortedException", "IOException" and "SocketException" messages occuring inside .NET. If I retry the activity then (most of the time) it will subsequently succeed.
It is as if the proxy instance that the Windsor WCF client returns is becoming invalid, but rather than silently destroying it and creating a new one it lets the error flow through and instead creates a new one one on the next request. Does that make any sense? Is anyone out there actually using this facility in a production non- web application? The documentation is non-existent, the few examples I have seen are either web app based, out of date or too simple to be useful (as are the unit tests). I'm banging my head against the wall with this - it could be something really dumb I am doing in my usage but without relevant examples it is impossible to know. I'm very close to giving up on WCF and going back to "trusty" .NET remoting. I have posted a small repro project showing how I register the service hosts and client which you can download from here: http://www.kiwidude.com/WcfDemo.zip Here is an example exception stack trace of the exception... System.ServiceModel.CommunicationException: The socket connection was aborted.
