Question

In a code I’m refactoring, I have the following situation:

void Plugin(IExternalService service)
{
    var facade = new Facade(
        new ExternalServiceWrapper(service),
        new Dependency1(),
        new Dependency2());
}

Where Dependency1 and Dependency2 are implementations of IDependency1 and IDependency2.

How can I convert this to a registration within Windsor installer? I can’t seem to figure our how to pass the instance of IExternalService to the container.

EDIT I’m not in control of the Plugin’s creation. I’d like to use it as a composition root to wire all the dependencies.

To register an existing instance, you can use the Instance method:

container.Register(Component.For<IExternalService>().Instance(service));
