This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

Properties

DebugView	This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.
DeclaringEntityType	Gets the dependent entity type. This may be different from the type that Properties are defined on when the relationship is defined a derived type in an inheritance hierarchy (since the properties may be defined on a base type).
IsReadOnly	Indicates whether the current object is read-only. (Inherited from AnnotatableBase)
Item[String]	Gets the value annotation with the given name, returning `null` if it does not exist. (Inherited from AnnotatableBase)
Item[String]	Gets the value annotation with the given name, returning `null` if it does not exist. (Inherited from RuntimeAnnotatableBase)
PrincipalEntityType	Gets the principal entity type that this relationship targets. This may be different from the type that PrincipalKey is defined on when the relationship targets a derived type in an inheritance hierarchy (since the key is defined on the base type of the hierarchy).
PrincipalKey	Gets the primary or alternate key that the relationship targets.
Properties	Gets the foreign key properties in the dependent entity.
