Declaration

C#

public override object CommitTransactionAsync(
    AsyncCommitCallback callback
)

VB.NET

Public Overrides Function CommitTransactionAsync(
    callback As AsyncCommitCallback
) As Object

Parameters

Name	Type	Description
callback	AsyncCommitCallback	An AsyncCommitCallback delegate to be called after the changes have been saved to a data store. Use a callback to store the exception information passed as a parameter, and use this information later to raise the exception again, within the original thread. Do not raise exceptions or modify persistent objects within a callback.

Returns

Type	Description
Object	An object identifying the current asynchronous operation, intended for internal use.

Remarks

All data modifications made since the ExplicitUnitOfWork.BeginTransaction method call can be committed (ExplicitUnitOfWork.CommitTransaction, CommitTransactionAsync, UnitOfWork.CommitChanges, or UnitOfWork.CommitChangesAsync) or discarded (ExplicitUnitOfWork.RollbackTransaction).

Calling the CommitTransactionAsync method performs the following:

• Asynchronously flushes all data modifications via the Session.FlushChangesAsync method call.
• Raises the Session.BeforeCommitTransaction event. Once an explicit transaction is committed, the Session.AfterCommitTransaction event is raised.
