IoC (Windsor) - What is the "default interface"?

Question

Can someone explain the difference between

container.Register(AllTypes.FromAssemblyContaining(typeof(BigCompanyRepository))
 .WithService.DefaultInterface()

and

container.Register(AllTypes.FromAssemblyContaining(typeof(BigCompanyRepository))
 .WithService.AllInterfaces()

What is meant by default interface?

Answer 1

This is a heuristic that searches for an implementation of an interface by removing the leadingI :

• IFoo → Foo
• IBar → Bar
• IKitchenSink → KitchenSink

However, in my opinion, using this function smells like a redundant 1: 1 interface .
