I have recently posted three WCF Adapter samples off the BizTalk Server Developer Center at http://msdn2.microsoft.com/en-us/biztalk/bb608378.aspx, Two samples were released today. The first one is of a WCF message intemediary where an incoming WCF message to BizTalk is dynamically channeled to the correct version of the the WCF service. The second one is shows custom message interception during BizTalk Server's binding processing of an outgoing WCF message. The third sample was published in January and is an example of using pure WCF messaging with the WCF adapters.
