Remarks
The base class keeps a cache of values that have been retrieved, and therefore only calls this method once per data source information property. Thus, the implementation of this method need not cache values itself.
Notes to Inheritors
The base implementation of this method returns nulla null reference (Nothing in Visual Basic).
