Scenarios:

1. TransactionAutoComplete set to false requires SessionMode.Required.

 [OperationBehavior(TransactionScopeRequired = true, TransactionAutoComplete=false)]
        [TransactionFlow(TransactionFlowOption.Mandatory)]
        public string UpdateStatus(string text)
        {
            count++;
            return String.Format("{0}", count);
        }

2. it has one or more IsTerminating or non-IsInitiating operations, but it does not have the SessionMode property set to SessionMode.Required. The IsInitiating and IsTerminating attributes can only be used in the context of a session.

[OperationContract(IsTerminating=true)]
        string UpdateStatus(string text);

   [OperationContract(IsInitiating=false)]
        string UpdateStatus(string text);
