It appears ES2.5 can connect (from orchestration) to WCF service which is using basicHttpBinding but cannot understand wsHttpBinding which is the "recommended" binding for WCF web services (returns "Undefined portType"). I am trying to find out if this is indeed the case and if not if there is any documentation / blogs which would explain how to connect to service which is using wsHttpBinding (was not able to find anything relevant). Thank you.
