Yes, Ive tested and i've same problem here:
[TestFixture]
public class CastleTest
{
[Test]
public void Test()
{
var container = new WindsorContainer();
container.AddFacility<FactorySupportFacility>();
container.Register(Component.For<IEnumerable<ISample
>>()
.UsingFactoryMethod(k =>
Mocks.Of<ISample>().Where(s => s.Name == "Test").Take(10).ToArray()),
Component.For<SomeService>());
container.Resolve<IEnumerable<ISample
>>().Count().Should().Be.EqualTo(10);
var service = container.Resolve<SomeService>();
service.CountSamples().Should().Be.EqualTo(10);
}
}
public class SomeService
{
private readonly IEnumerable<ISample> samples;
public SomeService(IEnumerable<ISample> samples)
{
this.samples = samples;
}
public int CountSamples()
{
return samples.Count();
}
}
public interface ISample
{
string Name { get; set; }
}
I've never done this before, so i am confused too. and this confused me:
Why is Windsor not able to inject array or list of components?

Windsor, *by default when you have dependency on IFoo[], IEnumerable<IFoo>
or IList<IFoo> will check if you have a component registered for that exact
type (array or list of IFoo),* not if you have any components registered for
IFoo (array of components, is not the same as a component which is an
array). You can change the behavior to say "When you see array or list of
IFoo just give me all IFoos you can get" you use CollectionResolver.
