Answer / rahul bhute

We can specify transaction in 3 ways in WCF:-

TransactionFlowOption.NotAllowed

This is a default option. Using this option no transaction
will be propagated across the binding. If any client
attempts to call the WCF service in a transaction it will
be ignored for this option.

TransactionFlowOption.Allowed

This option specifies that client can call this WCF service
in a transaction. It’s not compulsory that the service
needs to be called in a transaction. You can call without
the transaction also.

TransactionFlowOption.Mandatory

This option specifies that client must call the WCF service
in a transaction mode. If the WCF service is called without
transaction, ‘FaultException’ will be raised.
