Constructors

ReferenceReferenceBuilder<TEntity,TRelatedEntity>(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<TEntity,TRelatedEntity>(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	Gets the internal builder being used to configure this relationship. (Inherited from ReferenceReferenceBuilder)
DeclaringEntityType	Gets the first entity type used to configure this relationship. (Inherited from InvertibleRelationshipBuilderBase)
Metadata	The foreign key that represents this relationship. (Inherited from ReferenceReferenceBuilder)
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.
HasForeignKey<TDependentEntity>(Expression<Func<TDependentEntity,Object>>)	Configures the property(s) to use as the foreign key for this relationship.
HasForeignKey<TDependentEntity>(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. (Inherited from ReferenceReferenceBuilder)
HasForeignKeyBuilder(EntityType, String, IReadOnlyList<PropertyInfo>)	This API supports the Entity Framework Core infrastructure and is not intended to be used directly from your code. This API may change or be removed in future releases. (Inherited from ReferenceReferenceBuilder)

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 ReferenceReferenceBuilder)
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.
HasPrincipalKey<TPrincipalEntity>(Expression<Func<TPrincipalEntity,Object>>)	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<TPrincipalEntity>(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).

(Inherited from ReferenceReferenceBuilder)
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.
OnDelete(DeleteBehavior)	Configures how a delete operation is applied to dependent entities in the relationship when the principal is deleted or the relationship is severed. (Inherited from ReferenceReferenceBuilder)
