Remarks
Define a class derived from this if you want to do something whenever a transaction is opened.
Apply the RuleOnAttribute attribute to the class.
You can also define rules for when a transaction is committing (TransactionCommittingRule) and when a transaction is being rolled back (TransactionRollingBackRule).
For more information and examples, see Rules Propagate Changes Within the Model.
