Assembly: System.Transactions (in system.transactions.dll)
In the first (prepare) phase of a two phase commit, a resource manager implementing the Prepare method of the IEnlistmentNotification interface, calls this method to indicate that the transaction can be committed.
The resource manager can call the Done method at anytime before it has called this method. By doing so, the enlistment is casting a read only vote, meaning that it votes commit on the transaction but does not need to receive the final outcome.
Once this method is called by an enlistment and before it returns, it is possible that another thread or this same thread could make a call into the same enlistment method such as Rollback to perform a rollback. This can result in a deadlock situation if the resource manager implementation does not release resource locks until after this method returns.
