Difference between publishing schema and publishing an orchestration as a WCF Service

One the major differences for publishing schema and publishing an orchestration as a WCF Service is the Coupling factor. Publishing an orchestration as a WCF Service leads to tight coupling. Where as publishing schema as a WCF Service achieves loose coupling.

When an orchestration is published as a WCF Service, the data (message) received via the WCF Service will be directly bound the Orchestration which is published.

On the other hand when a schema is published as a WCF Service, the data (BizTalk message) received via the WCF Service will be published to the BizTalk Server Message Box and hence any number of subscribers can subscribe for the message.
