How to: Edit and Delete Navigation Properties (Entity Data Model Tools)
Navigation properties are shortcut properties that are used to locate the entities at the ends of an association in a conceptual model. Navigation properties can be created when you create an association between two entity types. For more information, see How to: Create and Modify Associations (Entity Data Model Tools).
If foreign keys are not exposed on entity types in a conceptual model, navigation properties are required to access entity types at the end of an association. For more information, see Defining and Managing Relationships (Entity Framework).
This topic shows how to edit and delete navigation properties.
