Introduction
The Entity Types includes one or more Navigation
Properties. Navigation Properties describe the navigation path between the relationship of
an entity. It is the property of an Entity that represents a link from the Entity to one or
more related Entities. The Navigation Property is tied to an Association Type and allows
the navigation from one end of the Entity Type that declares the Navigation Property, to
the other related end. Navigation property is required to create a link from one entity to
