Неразрешенный DI в ядре aspnet с lightinject

Question

Извините за длинный текст!

Я пытаюсь создать прослушиватель сообщений для RabbitMQ в ядре aspnet 2.1.Как только я отправляю сообщение, я получаю эту ошибку в журнале:

        {
            Log.Info($"Received message with id {context.MessageId}");
    }
}

Answer 1

Очевидно, я должен был использовать следующий код:

endpointConfiguration.UseContainer<ServicesBuilder>(
                customizations: customizations =>
                {
                    customizations.ExistingServices(services);
                });

Работая после того, как я следовал: https://docs.particular.net/samples/dependency-injection/aspnetcore/
