public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder? HasNoRelationship (System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> properties, Microsoft.EntityFrameworkCore.Metadata.IConventionKey principalKey, Microsoft.EntityFrameworkCore.Metadata.IConventionEntityType principalEntityType, bool fromDataAnnotation = false);

abstract member HasNoRelationship : System.Collections.Generic.IReadOnlyList<Microsoft.EntityFrameworkCore.Metadata.IConventionProperty> * Microsoft.EntityFrameworkCore.Metadata.IConventionKey * Microsoft.EntityFrameworkCore.Metadata.IConventionEntityType * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder

Public Function HasNoRelationship (properties As IReadOnlyList(Of IConventionProperty), principalKey As IConventionKey, principalEntityType As IConventionEntityType, Optional fromDataAnnotation As Boolean = false) As IConventionEntityTypeBuilder

Parameters

properties

IReadOnlyList<IConventionProperty>

The properties that the foreign key is defined on.

principalKey

IConventionKey

The primary or alternate key that is referenced.

principalEntityType

IConventionEntityType

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).

fromDataAnnotation

Boolean

Indicates whether the configuration was specified using a data annotation.

Returns

IConventionEntityTypeBuilder

The same builder instance if the relationship was removed or didn't exist, null otherwise.

HasNoRelationship(IConventionForeignKey, Boolean)

Removes a foreign key from this entity type.

public Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder? HasNoRelationship (Microsoft.EntityFrameworkCore.Metadata.IConventionForeignKey foreignKey, bool fromDataAnnotation = false);

abstract member HasNoRelationship : Microsoft.EntityFrameworkCore.Metadata.IConventionForeignKey * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionEntityTypeBuilder

Public Function HasNoRelationship (foreignKey As IConventionForeignKey, Optional fromDataAnnotation As Boolean = false) As IConventionEntityTypeBuilder

Parameters

foreignKey

IConventionForeignKey

The foreign key to be removed.

fromDataAnnotation

Boolean

Indicates whether the configuration was specified using a data annotation.

Returns

IConventionEntityTypeBuilder

The same builder instance if the foreign key was removed, null otherwise.
