DependentTransaction Class

.NET Framework (current version)

Describes a clone of a transaction providing guarantee that the transaction cannot be committed until the application comes to rest regarding work on the transaction. This class cannot be inherited.

The DependentTransaction is a clone of a Transaction object created using the DependentClone method. Its sole purpose is to allow the application to come to rest and guarantee that the transaction cannot commit while work is still being performed on the transaction (for example, on a worker thread).

When the work done within the cloned transaction is finally complete and ready to be committed, it can inform the creator of the transaction using the Complete method. Thus you can preserve the consistency and correctness of data.

The DependentCloneOption enumeration is used to determine the behavior on commit. This behavior control allows an application to come to rest, as well as provides concurrency support. For more information on how this enumeration is used, see Managing Concurrency with DependentTransaction.
