Hi,
What you want to use is the typed factory facility
http://docs.castleproject.org/Default.aspx?Page=Typed-Factory-Facility-interface-based-factories&NS=Windsor&AspxAutoDetectCookieSupport=1
So first, add the facility to your container:
var container = new WindsorContainer();
container.AddFacility<TypedFactoryFacility>();
Then register your component, and also register a factory for it:
container.Register(
Component.For<AbExternalProvider>().ImplementedBy<ExternalConcrete>().LifestyleTransient(),
Component.For<Func<string, AbExternalProvider>>().AsFactory());
Now resolve your factory and get your component:
var factory = container.Resolve<Func<string, AbExternalProvider>>();
var externalProvider = factory("SomeString");
You can also create an interface for the factory instead of using a Func if
it makes the code easier to understand.
I haven't actually compiled any of that code - just doing it from memory.
Hopefully it should do the trick.
Cheers,
Adam
