InMemoryTransport/Binding & WampAuthenticationHost

[esso23]

Hi again Elad,

I have another issue - when registering InMemoryBinding with WampAuthenticationHost, the call to RegisterTransport fails with:
System.ArgumentException: 'Got no binding. Expected at least one binding. Parameter name: bindings'
Apparently the problem is in WampAuthenticationHost.RegisterTransport:

IEnumerable<IWampBinding> authenticationBindings =
                bindings.Select(binding => CreateAuthenticationBinding((dynamic) binding))
                        .Cast<IWampBinding>()
                        .Where(x => x != null);

as authenticationBindings is empty after the call.

Repro:

using System;
using System.Reactive.Concurrency;
using WampSharp.Binding;
using WampSharp.Fleck;
using WampSharp.V2;
using WampSharp.V2.Authentication;
using WampSharp.V2.Binding;
using WampSharp.V2.Client;
using WampSharp.V2.MetaApi;
using WampSharp.V2.Transports;

namespace WampRouter
{
    class Program
    {
        private static WampChannelFactory mChannelFactory;
        private static InMemoryTransport mInMemoryTransport;
        private static InMemoryBinding mInMemoryBinding;

        class AuthFactory : IWampSessionAuthenticatorFactory
        {
            public IWampSessionAuthenticator GetSessionAuthenticator(WampPendingClientDetails details,
                IWampSessionAuthenticator transportAuthenticator)
            {
                throw new NotImplementedException();
            }
        }

        static void Main()
        {
            JTokenJsonBinding jsonBinding = new JTokenJsonBinding();
            JTokenMsgpackBinding msgPackBinding = new JTokenMsgpackBinding();

            var host = new WampAuthenticationHost(new AuthFactory());
            FleckWebSocketTransport websocketTransport = new FleckWebSocketTransport("ws://0.0.0.0:50002/");
            host.RegisterTransport(websocketTransport, jsonBinding, msgPackBinding);

            mInMemoryBinding = new InMemoryBinding();
            mInMemoryBinding.AddFormatter(jsonBinding.Formatter);
            mInMemoryBinding.AddFormatter(msgPackBinding.Formatter);
            mChannelFactory = new WampChannelFactory();
            mInMemoryTransport = new InMemoryTransport(DefaultScheduler.Instance);
            host.RegisterTransport(mInMemoryTransport,
                new IWampBinding[] { mInMemoryBinding });

            host.Open();
            Console.WriteLine("Host running.");

            Console.ReadLine();
        }
    }
}

Thanks
Esso

Should be fixed in 18.8.1.

Tried it just now, everything is working fine.
