using System;
using Castle.Windsor;
using Castle.MicroKernel.Registration;
using System.Reflection;
using Castle.MicroKernel.Resolvers.SpecializedResolvers;

namespace Windsor
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            var container = new WindsorContainer ();

            container.Register (Component.For (typeof(IIface<, >)).ImplementedBy (typeof(HandlerImpl<, >)));
            //container.Register (Component.For (typeof(IIface<, >)).ImplementedBy(typeof(Impl2)));
            container.Kernel.Resolver.AddSubResolver (new ArrayResolver (container.Kernel));
            var normal = container.ResolveAll<IIface<Impl2, Stub>> ();
            var ex = container.ResolveAll<IIface<Impl1, Stub>> ();

            //var qwe = new HandlerImpl<Impl1, Stub> ();

            Console.WriteLine("Hello World!");
        }
    }

    public class Base {}

    public class Stub {}

    public interface AdditionalIface
    {
    }

    public interface IIface<T1, T2> where T1 : Base where T2 : class
    {
        T1 Command { get; set; }
    }

    public class HandlerImpl<T1, T2> : IIface<T1, T2> where T1 : Base, AdditionalIface where T2 : class
    {
        public T1 Command { get; set; }
    }

    public class Impl1 : Base
    {
    }

    public class Impl2 : Base, AdditionalIface
    {
    }
}

So, now if i do smth like:

var normal = container.ResolveAll<IIface<Impl2, Stub>> (); // this works ok
var ex = container.ResolveAll<IIface<Impl1, Stub>> (); // this throws exception abou not fullfilled constraints
// instead i want it just show no resolved implementations

Is there any way to make this work as I want it to?

Answer 1

Actually this seems to be a bug in Windsor’s code.

Update:

And it’s fixed now
