ITransactionProperty

Used to get the transaction resource pool.
ITransactionProxy

Provides a way for a COM+ transaction context to work with a non-DTC transaction.
ITransactionResourcePool

Maintains a list of pooled objects, keyed by IObjPool, that are used until the transaction completes.
ITransactionStatus

Used to discover the status of the transaction that is completed by the call to CoLeaveServiceDomain when CServiceConfig is configured to use transactions in the call to CoEnterServiceDomain.
ObjectContext

Provides access to the current object's context. An object's context is primarily used when working with transactions or dealing with the security of an object. (ObjectContext)
ObjectControl

If you implement this interface in your component, the COM+ run-time environment automatically calls its methods on your objects at the appropriate times.
SecurityProperty

Retrieves information about the current object's original caller and direct caller.
