Unable to resolve an array in Castle Windsor

I cannot get Castle Windsor (3.0) to resolve an array. I've done it before and I have other arrays resolved, so this is confounding.

First I add a CollectionResolver, which does arrays

_container.Kernel.Resolver.AddSubResolver(new CollectionResolver(_container.Kernel));

Then, I register all my classes based on this interface, of which there are about 6

container.Register(AllTypes.FromThisAssembly().BasedOn<ISearchSource>());

They are definitely in the same assembly and in the debugger, I can see these classes are in the list of components eg.

public class ViewsSearchSource : ISearchSource {...}

Yet in the class that resolves this, like this... 

public SearchBot(ISearchSource[] searchSources)

I get

'SearchBot' is waiting for the following dependenciesService 'ISearchSource[]' which was not registered.

I've even tried adding an ArrayResolver (as well as CollectionResolver) explicitly. Same error.

What am I missing here?

AllInterfaces is necessary due to your dependency is on interface type: "AllTypes.FromThisAssembly().BasedOn()" picks all types implementing ISearchSource, but those types will be registered in the container with the concrete type, not with the interface(which has been used instead as dependency).

PS: I suggest you to use Classes instead of AllTypes.

"WithServiceDefaultInterfaces()" should be enough in your case.

Keep in mind windsor resolves dependencies according to registration: IOW you have to flag(during component registration) your concrete with all its interface you will use as dependency.

While you are in debug, add a watch/breakpoint on the container to see all registered component and the interface/concrete "linked/assigned" to you component: that unveil the magic behind the resolution.

I needed to register like this

container.Register(AllTypes.FromThisAssembly().BasedOn<ISearchSource>().WithService.AllInterfaces());

ie had to add WithService.AllInterfaces());

I actually don't understand why this AllInterfaces is necessary here, but it works.
