Class HierarchicalLifetimeManager
A special lifetime manager which works like ContainerControlledLifetimeManager, except that in the presence of child containers, each child gets it's own instance of the object, instead of sharing one in the common parent.
Inherited Members
Namespace: Unity.Lifetime
Assembly: Unity.Abstractions.dll
Syntax
public class HierarchicalLifetimeManager : SynchronizedLifetimeManager, IDisposable, IFactoryLifetimeManager, ITypeLifetimeManagerRemarks
The Unity container allows creating hierarchies of child containers. This lifetime creates local singleton for each level of the hierarchy. So, when you resolve a type and this container does not have an instance of that type, the container will create new instance. Next type the type is resolved the same instance will be returned.
If a child container is created and requested to resolve the type, the child container will create a new instance and store it for subsequent resolutions. Next time the child container requested to resolve the type, it will return stored instance.
If you have multiple children, each will resolve its own instance.
