EF.Toolkits.AutoComments

На основе файлов документации позволяет автоматически добавлять комментарии к столбцам и таблицам. Также поддерживает описание значений Enum через атрибут AutoCommentsEnumValues. В проект необходимо добавить генерацию файла документации и указать его имя при подключении расширения.

    <PropertyGroup>
        <GenerateDocumentationFile>true</GenerateDocumentationFile>
        <DocumentationFile>Comments.xml</DocumentationFile>
    </PropertyGroup>

EF.Toolkits.CustomSql

Добавляет возможность автоматически добавлять пользовательский SQL в код миграции с поддержкой изменения. Для каждого пользовательского SQL необхдимо определить 2 скрипта: на создание (Up) и на удаление (Down). Соответствующие скрипты попадут в файл миграции. В начало ммиграции добавляются скрпты для удаления, в конце миграции на добавление.

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder
        .AddCustomSql("animals_view", "SELECT * FROM animals a WHERE a.type = 1", "DROP VIEW  IF EXISTS animals_view");
}

Провайдер для автоматического добавления триггеров. Зависит от EF.Toolkits.CustomSql

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Figure>(entity =>

       entity.BeforeInsert("set_square", "new.square = 0");

       entity.BeforeUpdate("prevent_update_with_negative_square", "IF new.square < 0 THEN raise exception 'square negative' END IF;");
    });
}
