How to use RegisterType for a class that implements multiple interfaces?

Question

Given:

public interface IFeedOperations : IOperationsWithPreInstalledData
{
    ...
}

public class FeedOperations : IFeedOperations
{
}

How do I use RegisterType for a class that implements IFeedOperations AND therefore the IOperationsWithPreInstalledData as well?

public class FeedsInstaller : IDependencyInstaller
{
    public void Install(IDependencyContainer container)
    {
        container.RegisterType(typeof(IFeedOperations), typeof(FeedOperations));
        container.RegisterType(typeof(IOperationsWithPreInstalledData), typeof(FeedOperations));
    }
}

The current code yields the following error. And if I remove the second RegisterType then I get no results when I call container.ResolveAll<IOperationsWithPreInstalledData>().

Component ...Feeds.FeedOperations could not be registered. There is already a component with that name. Did you want to modify the existing component instead? If not, make sure you specify a unique name.

And if I remove the second RegisterType then I get no results when I call container.ResolveAll<IOperationsWithPreInstalledData>(). Castle Windsor doesn't seem to see that a class implementing IFeedOperations also implements IOperationsWithPreInstalledData.

How can I register my implementing class with Castle Windsor so that it knows my class implements both interfaces -- or rather that either interface can be resolved by my class.

Do you care if two instances of your class will be created (one for each interface)? — svick

Would prefer just one instance but I'm not picky in this case. — kingdango

Also, IDependencyContainer doesn't seem to be any type from Castle. Is that your custom interface? — svick

So, are you asking how to use your own code? I'm afraid we can't help you with that. — svick

container.Register(Component.For<IFoo,IBar>().ImplementedBy<FooBar>());

Yes, this is what I did to get it working -- figured it out on my own but happy to give you the credit for the answer. Thank you for responding!

is it the same as writing For<IFoo>().Forward<IBar>()?
