Syntax
public class ContainerControlledLifetimeManager : SynchronizedLifetimeManager, IDisposable, IInstanceLifetimeManager, IFactoryLifetimeManager, ITypeLifetimeManager
Remarks

Per Container lifetime allows a registration of an existing or resolved object as a scoped singleton in the container it was created or registered. In other words this instance is unique within the container it war registered with. Child or parent containers could have their own instances registered for the same contract.

When the ContainerControlledLifetimeManager is disposed, the instance is disposed with it.
