Can I register my types in modules in Unity like I can in Autofac?

Question

I am fairly familiar with Autofac and one feature that I really love about Autofac is the registering of modules. Does anyone know how I can do this with Unity? I'm having a hard time finding which terms to use in Google to come up with the unity equivalent if there is one.

  public class Global : HttpApplication, IContainerProviderAccessor { private static IContainerProvider _containerProvider; protected void Application_Start(object sender, EventArgs e) { var builder = new ContainerBuilder(); builder.RegisterModule(new MyWebModule()); _containerProvider = new ContainerProvider(builder.Build()); } [...] public IContainerProvider ContainerProvider { get { return _containerProvider; } } } public class MyWebModule: Module { protected override void Load(ContainerBuilder builder) { builder.RegisterModule(new ApplicationModule()); builder.RegisterModule(new DomainModule()); } } public class ApplicationModule: Module { protected override void Load(ContainerBuilder builder) { builder.Register(c => new ProductPresenter(c.Resolve<IProductView>())) .As<ProductPresenter>() .ContainerScoped(); } }

Actually, you can do trivially with Unity container extensions.

public class Global : HttpApplication, IContainerProviderAccessor { private static IContainerProvider _containerProvider; protected void Application_Start(object sender, EventArgs e) { var container = new UnityContainer(); container.AddNewExtension<MyWebModule>(); _containerProvider = new ContainerProvider(container); } [...] public IContainerProvider ContainerProvider { get { return _containerProvider; } } } public class MyWebModule : UnityContainerExtension { protected override void Initialize() { Container.AddNewExtension<ApplicationModule>(); Container.AddNewExtension<DomainModule>(); } } public class ApplicationModule: UnityContainerExtension { protected override void Initialize() { Container.RegisterType<ProductPrensenter>( new ContainerControlledLifetimeManager(), new InjectionFactory(c => new ProductPresenter(c.Resolve<IProductView>()))); } }

You can't. Just use Autofac or Windsor. You will find there's a lot missing in Unity and what's there works in unexpected ways. It's just not worth your time.

What specifically is missing in Unity? What does it do that is unexpected?
