Registering a service with and without a factory always defaults to without

[knodel12]

The main issue is that when you register a factory alongside a default implementation, resolving either always results in the default implementation.

  LightInject 5.0.3.0

• Platform
  .NET Framework 4.7.2

• An example that shows the issue.

var container = new ServiceContainer();
container.Register<IPushNotificationSender, FirebasePushNotificationsSender>(new PerContainerLifetime());
container.Register<IPushNotificationSender, NotificationsWebPushSender>
    (DeviceMessageTypes.Chrome.ToString(), new PerContainerLifetime());
container.Register<IPushNotificationSender, NotificationsWebPushSender>
    (DeviceMessageTypes.FireFox.ToString(), new PerContainerLifetime());
container.Register<IPushNotificationSender, NotificationsGcmPushSender>
    (DeviceMessageTypes.GCM.ToString(), new PerContainerLifetime());
container.Register<IPushNotificationSender, NotificationsApnPushSender>
    (DeviceMessageTypes.APN.ToString(), new PerContainerLifetime());
container.Register<DeviceMessageTypes, IPushNotificationSender>((factory, value) => factory.GetInstance<IPushNotificationSender>(value.ToString()));

var factory = container.GetInstance<Func<DeviceMessageTypes, IPushNotificationSender>>();
var mainImpl = container.GetInstance<IPushNotificationSender>();

var factoryImpl = factory(DeviceMessageTypes.APN);
if (factoryImpl.GetType().Name == mainImpl.GetType().Name)
{
    // These shouldn't be the same...  
    // The factory should resolve to the factory function in the registration.
    Console.WriteLine("Expected factory to resolve to different type.");
    Console.WriteLine($"Expected Type: {typeof(NotificationsApnPushSender).Name}");
    Console.WriteLine($"Resolved Type: {factoryImpl.GetType().Name}");
}
