Remarks

A single EntitySpan represents the relations among a graph of entities. You must be able to "walk" the spans without jumping or backtracking. For example, a single EntitySpan might be defined for Customer -> Order -> OrderDetails, because relationships are defined between each of these entities and navigation is straightforward. You cannot, however define a single span for Customer -> Order -> OrderDetails -> Employee, because navigation from OrderDetails to Employee is not defined. In this case two spans would be required, one for Customer -> Order -> OrderDetails, and another for Customer -> Order -> Employee.

The EntitySpan is used in retrieving an entity graph with EntityManager.FindEntityGraph
