Understanding the distributed transaction support of a WCF service

As we have seen, the distributed transaction support of a WCF service depends on the binding of the service, the operation contract attribute, the operation implementation behavior, and the client applications.

The following table shows some possible combinations of the WCF-distributed transaction support:

Binding permits transaction flow	Client has transaction flow enabled	Service contract opts in transaction	Service operation requires a transaction scope	Possible result
True	Yes	Allowed or Mandatory	True	Service executes under the flowed-in transaction
True or false	No	Allowed	True	Service creates and executes within a new transaction
True	Yes or no	Allowed	False	Service executes without a transaction
True or false	No	Mandatory	True or false	SOAP exception
True	Yes	NotAllowed	True or false	SOAP exception
