설명

메시지 싱크에서 사용 하는 IMessage 서버 싱크 체인 또는 클라이언트 싱크 체인에 배치할 수 있습니다. 메시지 개체를 메시지 싱크에서 체인을 통해 메시지 싱크로 전달 되 고 작업 식별자, 엔보이 정보 및 매개 변수 등의 명명 된 속성의 집합을 전달 합니다.

구현 하는 개체는 IMessage 인터페이스를 메시지 개체로 간주 되기 위해 최소 자격 요건을 충족 합니다. 메시지 싱크를 통해 받은 개체는 다음 싱크로 전달 되어야 하 없지만이 경우가 많습니다.

Propertybag에서 개체를 직렬화 할 수 없는, 하지만 애플리케이션 도메인에서 이동 하는 속성을 직렬화 해야 하므로이 고려해 야 할 메시지 싱크 구현 자가 필요 합니다.
