WCF from theory to Practice (13): Business Polling

Through WCF from theory to practice: the study of transactions, we understand the WCF implementation of the transaction of some basic knowledge, but the transaction in WCF is not so simple, we lack one of the most important function: The business vote, the so-called business vote is a flexible control of the way the transaction is committed, In the above we set the TransactionAutoComplete of the service method to be true, which means that the method automatically votes in favour without exception, but sometimes we want the transaction to be committed only when a certain data satisfies a specific condition in the operation. So the above realization is obviously not satisfied with the demand, at this time we can use OperationContext.Current.SetTransactionComplete (), the display of voting.
