Resolving Instances with Delegates in Unity

Question

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

Accepted Answer

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.
