Hello. Please, can somebody advise me? I create WCF library that realizes endpoint net-pipe for job with external WCF.I placed lib in Windows Service. But I dont know how to make data exchange from library without usage of WCF client-server mechanism. How can I put or get data from running WCF service? for example I want to register WCF errors in Eventlog or give parameters to service for transfer them for clients connected to WCF. Thanks a lot
