ServiceManager.AddService Method (Type, ServiceCreatorCallback, Boolean)

Adds the specified service to the service container, and optionally promotes the service to parent service containers.

public abstract void AddService(
   Type serviceType,
   ServiceCreatorCallback callback,
   bool promoteToParent
);

serviceType: The type of service to add.
callback: A callback object that is used to create the service. This allows a service to be declared as available, but delays the creation of the object until the service is requested.
promoteToParent: true to promote this request to any parent service containers; otherwise, false.
