What the different transaction options ?

In the previous code we have use ‘TransactionFlowOption’. 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.
