Public Sub RemoveForeignKey (foreignKey As IMutableForeignKey)
Public Function RemoveForeignKey (foreignKey As IMutableForeignKey) As IMutableForeignKey

Parameters

foreignKey
IMutableForeignKey

The foreign key to be removed.

Returns

IMutableForeignKey

The removed foreign key.

Applies to

RemoveForeignKey(IReadOnlyForeignKey)

Removes a foreign key from this entity type.

public Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey? RemoveForeignKey (Microsoft.EntityFrameworkCore.Metadata.IReadOnlyForeignKey foreignKey);
abstract member RemoveForeignKey : Microsoft.EntityFrameworkCore.Metadata.IReadOnlyForeignKey -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey
Public Function RemoveForeignKey (foreignKey As IReadOnlyForeignKey) As IMutableForeignKey

Parameters

foreignKey
IReadOnlyForeignKey

The foreign key to be removed.

Returns

IMutableForeignKey

The removed foreign key, or null if the index was not found.

Applies to

RemoveForeignKey(IReadOnlyList<IProperty>, IKey, IEntityType)

Removes a relationship from this entity.

public Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey RemoveForeignKey (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IProperty> properties, Microsoft.EntityFrameworkCore.Metadata.IKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IEntityType principalEntityType);
abstract member RemoveForeignKey : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IProperty> * Microsoft.EntityFrameworkCore.Metadata.IKey * Microsoft.EntityFrameworkCore.Metadata.IEntityType -> Microsoft.EntityFrameworkCore.Metadata.IMutableForeignKey
Public Function RemoveForeignKey (properties As IReadOnlyList(Of IProperty), principalKey As IKey, principalEntityType As IEntityType) As IMutableForeignKey

Parameters

properties
IReadOnlyList<IProperty>

The properties that the foreign key is defined on.

principalKey
IKey

The primary or alternate key that is referenced.

principalEntityType
IEntityType

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 foreign key that was removed.

Applies to

Public Function RemoveForeignKey (properties As IReadOnlyList(Of IReadOnlyProperty), principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

Parameters

properties
IReadOnlyList<IReadOnlyProperty>

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).
