Remarks
Use this version if you have written rules and event handlers that use information passed in a transaction context object. Because rules are called in an arbitrary order at the end of a transaction, it is not possible to pass information to or between them directly. The transaction context is a dictionary in which any kind of information can be passed.
Examples
// In a rule:
UsefulInfo info = this.Store.TransactionManager.CurrentTransaction
.TopLevelTransaction.Context.ContextInfo["akey"] as UsefulInfo;
