I am trying to implement the state design pattern using C++/CLI. This pattern requires that the State class be a friend of the Context. But C++/CLI does not allow a friend class. I understand that this is also the case with C#. Has anyone implemented the state pattern with C++/CLI or C#? I would like to know how you got around the absence of friend class.
Its done using Association (or what all the cool kids are calling Dependency Injection). Inject the state into the context. See the implementation on DoFactory
