CollectionOwnershipBuilder<TEntity,TDependentEntity>.OwnsOne Method

Definition

Namespace:

Microsoft.EntityFrameworkCore.Metadata.Builders

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v2.2.6

Overloads

OwnsOne<TNewRelatedEntity>(String)	Configures a relationship where the target entity is owned by (or part of) this entity. The target entity key value is always propagated from the entity it belongs to. The target entity type for each ownership relationship is treated as a different entity type even if the navigation is of the same type. Configuration of the target entity type isn't applied to the target entity type of other ownership relationships. Most operations on an owned entity require accessing it through the owner entity using the corresponding navigation.
OwnsOne<TRelatedEntity>(Expression<Func<TDependentEntity,TRelatedEntity>>)	Configures a relationship where the target entity is owned by (or part of) this entity. The target entity key value is always propagated from the entity it belongs to. The target entity type for each ownership relationship is treated as a different entity type even if the navigation is of the same type. Configuration of the target entity type isn't applied to the target entity type of other ownership relationships. Most operations on an owned entity require accessing it through the owner entity using the corresponding navigation.
OwnsOne<TRelatedEntity>(Expression<Func<TDependentEntity,TRelatedEntity>>, Action<ReferenceOwnershipBuilder<TDependentEntity,TRelatedEntity>>)	Configures a relationship where the target entity is owned by (or part of) this entity. The target entity key value is always propagated from the entity it belongs to. The target entity type for each ownership relationship is treated as a different entity type even if the navigation is of the same type. Configuration of the target entity type isn't applied to the target entity type of other ownership relationships. Most operations on an owned entity require accessing it through the owner entity using the corresponding navigation.
OwnsOne<TRelatedEntity>(String, Action<ReferenceOwnershipBuilder<TDependentEntity,TRelatedEntity>>)	Configures a relationship where the target entity is owned by (or part of) this entity. The target entity key value is always propagated from the entity it belongs to. The target entity type for each ownership relationship is treated as a different entity type even if the navigation is of the same type. Configuration of the target entity type isn't applied to the target entity type of other ownership relationships. Most operations on an owned entity require accessing it through the owner entity using the corresponding navigation.
