Resolving Instances with Delegates in Unity

Question

Has Unity, since February of 2011, improved this delegate story to achieve parity with StructureMap?

Answer 1

Yes. Actually, this shipped with Unity 1.0 as the injection factory extension, so the blog post is wrong about the capability not being there.

In Unity 2.0 the story got a lot easier. You can do:

container.RegisterType<IWhatever>(
    new InjectionFactory(container => whateverFunctionYouWant()));

This results in a transient registration; you can use whatever lifetime manager you want.
