Please check that ".NET Features -> WCF Activation -> Non-HTTP activation" feature is installed("server manager -> add/remove features"). And I assume, that you host the service in IIS. In this case, please also check if net.tcp protocol is allowed for a web site(Web Site -> Advanced Settings -> Enabled Protocols) and "Net.Tcp Listner Adapter" windows service is running.
