Remarks

A CurrentValueRecord object contains a DbDataRecord view of the object or relationship tracked by an ObjectStateEntry.

CurrentValueRecord implements IExtendedDataRecord, which provides read-only access to the current values of entities, relationships, and metadata.

Implements methods that allow updates to the current values.
