GetOrAddForeignKey(IMutableEntityType, IMutableProperty, IMutableKey, IMutableEntityType)

Gets an existing relationship, or creates a new one if one is not already defined.

public static Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey GetOrAddForeignKey (this Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType entityType, Microsoft.EntityFrameworkCore.Metadata.IMutableProperty property, Microsoft.EntityFrameworkCore.Metadata.IMutableKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType principalEntityType);

static member GetOrAddForeignKey : Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType * Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey

<Extension()>
Public Function GetOrAddForeignKey (entityType As IMutableEntityType, property As IMutableProperty, principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

Parameters

entityType

IMutableEntityType

The entity type to get or add the foreign key to.

property

IMutableProperty

The property that the foreign key is defined on.

principalKey

IMutableKey

The primary or alternate key that is referenced.

principalEntityType

IMutableEntityType

The entity type that the 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).

Returns

IMutableForeignKey

The existing or newly created foreign key.

GetOrAddForeignKey(IMutableEntityType, IReadOnlyList<IMutableProperty>, IMutableKey, IMutableEntityType)

Gets an existing relationship, or creates a new one if one is not already defined.
