Adding forward with windsor facility

Question

I have a windsor facility that I need to use to add a forward to a registered component. For some reason I can't seem to figure out how to do this.

I have the ComponentRegistered event bound and I'm able to filter out what I need to add the additional interface to but I can't seem to add the forward. Here is what I have in my facility:

void KernelComponentRegistered(string key, IHandler handler)
{
    if (typeof(ICanDoMagic).IsAssignableFrom(handler.ComponentModel.Implementation))
    {
        // I don't know what goes here
    }
}
protected override void Init()
{
    Kernel.ComponentRegistered += KernelComponentRegistered;
}

and I have the following interfaces and class:

public interface ICanDoMagic

public interface IBasicInterface

public class BasicClass : IBasicInterface, ICanDoMagic

and here is the registration with windsor

container.Register(Component.For<IBasicInterface>().ImplementedBy<BasicClass>())

What I want to have happen is when the user registers things that implement ICanDoMagic (like I have in the registration above) I want to also register the ICanDoMagic interface for that class so they don't need to register it themselves. I think this is done with a forward but I don't know how to add it.

Answer 1

You want to attach to Kernel.ComponentModelCreated instead. This code will then work for you:

void KernelComponentModelCreated(ComponentModel model)
{
    if (typeof(ICanDoMagic).IsAssignableFrom(model.Implementation))
    {
        model.AddService(typeof(ICanDoMagic));
    }
}

This is somewhat similar to this question.
