public virtual Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey AddForeignKey (Microsoft.EntityFrameworkCore.Metadata.IMutableProperty property, Microsoft.EntityFrameworkCore.Metadata.IMutableKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType principalEntityType);

abstract member AddForeignKey : Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey
override this.AddForeignKey : Microsoft.EntityFrameworkCore.Metadata.IMutableProperty * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey

Public Overridable Function AddForeignKey (property As IMutableProperty, principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

Parameters

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 newly created foreign key.

AddForeignKey(IReadOnlyList<IMutableProperty>, IMutableKey, IMutableEntityType)

Adds a new relationship to this entity type.

public Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey AddForeignKey (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IMutableProperty> properties, Microsoft.EntityFrameworkCore.Metadata.IMutableKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType principalEntityType);

abstract member AddForeignKey : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IMutableProperty> * Microsoft.EntityFrameworkCore.Metadata.IMutableKey * Microsoft.EntityFrameworkCore.Metadata.IMutableEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey

Public Function AddForeignKey (properties As IReadOnlyList(Of IMutableProperty), principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

Parameters

properties

IReadOnlyList<IMutableProperty>

The properties 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 newly created foreign key.
