Remarks
When an object of a specific type is added to the model and you want to do something programmatically ,you define a class that is derived from this class.
A RuleOnAttribute attribute placed on the class indicates what type of object the rule works on and when the rule should be used.
The rule is called when the specified type of transaction is being rolled back in the model.
You can also define rules for when a transaction is beginning (TransactionBeginningRule) and when a transaction is committing (TransactionCommittingRule).
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
