Containercontrolledlifetimemanager Not Working

A special lifetime manager which works like ContainerControlledLifetimeManager, except that in the presence of child containers, each child gets it's own instance of.

By Shadi Namrouti, Rick Anderson, and Steve Smith. ASP.NET Core MVC controllers request dependencies explicitly via constructors. ASP.NET Core has built-in support for dependency injection (DI).DI makes apps easier to test and maintain. It’s only one object I am resolving. I thought about doing 100,000, but there is no point. I don’t know of any Xamarin.Forms app that needs 100,000 types resolved all at once. Connect and share knowledge within a single location that is structured and easy to search.

A special lifetime manager which works like ContainerControlledLifetimeManager,except that in the presence of child containers, each child gets it's own instanceof the object, instead of sharing one in the common parent.

Namespace: Unity.Lifetime

Assembly: Unity.Abstractions.dll

Syntax

Remarks

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.
