The ITransactionVoterNotifyAsync2 interface notifies a transaction voter of a vote request during the first phase of the two-phase commit protocol. The transaction voter returns a vote to either approve a commit outcome or abort the transaction through the ITransactionVoterBallotAsync2::VoteRequestDone method. The ITransactionVoterNotifyAsync2 interface also notifies the voter of commit, abort, heuristic, and in-doubt transaction outcomes during phase two through the inherited ITransactionOutcomeEvents interface.
Note
The ITransactionVoterNotifyAsync interface is no longer supported and applications must instead use the ITransactionVoterNotifyAsync2 interface.
