Constructors

ReferenceReferenceBuilder(IMutableEntityType, IMutableEntityType, IMutableForeignKey)	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.
ReferenceReferenceBuilder(InternalForeignKeyBuilder, ReferenceReferenceBuilder, Boolean, Boolean, Boolean, Boolean)	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

Builder	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. (Inherited from InvertibleRelationshipBuilderBase)
DeclaringEntityType	Gets the first entity type used to configure this relationship. (Inherited from InvertibleRelationshipBuilderBase)
Metadata	The foreign key that represents this relationship. (Inherited from InvertibleRelationshipBuilderBase)
RelatedEntityType	Gets the second entity type used to configure this relationship. (Inherited from InvertibleRelationshipBuilderBase)

Methods

HasAnnotation(String, Object)	Adds or updates an annotation on the relationship. If an annotation with the key specified in annotation already exists its value will be updated.
HasForeignKey(String, String[])	Configures the property(s) to use as the foreign key for this relationship.
HasForeignKey(Type, String[])	Configures the property(s) to use as the foreign key for this relationship.
HasForeignKeyBuilder(EntityType, String, IReadOnlyList<MemberInfo>)	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.
HasForeignKeyBuilder(EntityType, String, IReadOnlyList<String>)	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.
HasPrincipalKey(String, String[])	Configures the unique property(s) that this relationship targets. Typically you would only call this method if you want to use a property(s) other than the primary key as the principal property(s). If the specified property(s) is not already a unique constraint (or the primary key) then a new unique constraint will be introduced.
HasPrincipalKey(Type, String[])	Configures the unique property(s) that this relationship targets. Typically you would only call this method if you want to use a property(s) other than the primary key as the principal property(s). If the specified property(s) is not already a unique constraint (or the primary key) then a new unique constraint will be introduced.

HasPrincipalKeyBuilder(EntityType, String, IReadOnlyList<String>)	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.
IsRequired(Boolean)	Configures whether this is a required relationship (i.e. whether the foreign key property(s) can be assigned null).
OnDelete(DeleteBehavior)	Configures the operation applied to dependent entities in the relationship when the principal is deleted or the relationship is severed.
ResolveEntityType(String)	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.

Explicit Interface Implementations

IInfrastructure<IConventionForeignKeyBuilder>.Instance

Gets the value of the property being hidden. (Inherited from InvertibleRelationshipBuilderBase)

Extension Methods

HasConstraintName(ReferenceReferenceBuilder, String)

Configures the foreign key constraint name for this relationship when targeting a relational database.
