MemberEntry MemberEntry Class

Definition

Provides access to change tracking information and operations for a given property or navigation property.

Scalar properties use the derived class PropertyEntry, reference navigation properties use the derived class ReferenceEntry, and collection navigation properties use the derived class CollectionEntry.

Instances of this class are returned from methods when using the ChangeTracker API and it is not designed to be directly constructed in your application code.
