필드

Disabled	0	COM+는 개체의 컨텍스트를 결정할 때 구성 요소의 동기화 요구 사항을 무시합니다.
NotSupported	1	이 값을 가진 개체는 호출자의 상태에 관계 없이 동기화에 참여할 수 없습니다. 이 설정은 트랜잭션이 아니고 JIT(Just-In-Time) 활성화를 사용하지 않는 구성 요소에만 사용할 수 있습니다.
Required	3	구성 요소에서 만들어진 모든 개체가 동기화되는지 확인합니다.
RequiresNew	4	이 값을 가진 개체는 호출에 관련된 모든 구성 요소 대신 COM+가 컨텍스트와 아파트를 관리하는 새로운 동기화에 참여해야 합니다.
Supported	2	이 값을 가진 개체는 동기화가 있는 경우 동기화에 참여합니다.
