Declaration
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
To start a transaction, use the Session.BeginTransaction method. To commit all data modifications made since the start of the transaction and complete the transaction, call the CommitTransactionAsync or Session.CommitTransaction method. To discard these modifications, call the Session.RollbackTransaction method.
To determine if a transaction is in progress, use the Session.InTransaction property.
After the CommitTransactionAsync method is called, the Session.BeforeCommitTransaction event is raised.
Note
In a NestedUnitOfWork, calling the CommitTransactionAsync method throws the System.NotSupportedException since changes within these Units should be saved using only the main thread.
