Generiert ein SQL-Fragment für eine Fremdschlüsseleinschränkung eines AddForeignKeyOperation.

protected virtual void ForeignKeyConstraint (Microsoft.EntityFrameworkCore.Migrations.Operations.AddForeignKeyOperation operation, Microsoft.EntityFrameworkCore.Metadata.IModel model, Microsoft.EntityFrameworkCore.Migrations.MigrationCommandListBuilder builder);
protected virtual void ForeignKeyConstraint (Microsoft.EntityFrameworkCore.Migrations.Operations.AddForeignKeyOperation operation, Microsoft.EntityFrameworkCore.Metadata.IModel? model, Microsoft.EntityFrameworkCore.Migrations.MigrationCommandListBuilder builder);
abstract member ForeignKeyConstraint : Microsoft.EntityFrameworkCore.Migrations.Operations.AddForeignKeyOperation * Microsoft.EntityFrameworkCore.Metadata.IModel * Microsoft.EntityFrameworkCore.Migrations.MigrationCommandListBuilder -> unit
override this.ForeignKeyConstraint : Microsoft.EntityFrameworkCore.Migrations.Operations.AddForeignKeyOperation * Microsoft.EntityFrameworkCore.Metadata.IModel * Microsoft.EntityFrameworkCore.Migrations.MigrationCommandListBuilder -> unit
Protected Overridable Sub ForeignKeyConstraint (operation As AddForeignKeyOperation, model As IModel, builder As MigrationCommandListBuilder)

model
IModel

Das Zielmodell, das sein kann, wenn die Vorgänge ohne Modell vorhanden sind null .
