Alanlar

Disabled	0	COM+, nesnenin bağlamını belirlerken bileşenin eşitleme gereksinimlerini yoksayar.
NotSupported	1	Bu değere sahip bir nesne, çağıranın durumuna bakılmaksızın hiçbir zaman eşitlemeye katılmaz. Bu ayar yalnızca işlemsel olmayan ve tam zamanında (JIT) etkinleştirme kullanmayan bileşenler için kullanılabilir.
Required	3	Bileşenden oluşturulan tüm nesnelerin eşitlenmesini sağlar.
RequiresNew	4	Bu değere sahip bir nesne, COM+'nın çağrıya dahil olan tüm bileşenler adına bağlamları ve daireleri yönettiği yeni bir eşitlemeye katılmalıdır.
Supported	2	Bu değere sahip bir nesne varsa eşitlemeye katılır.
