Using an existing IoC Container in SignalR 2.0

Question

How can I use an existing IoC with SignalR 2.0?

From the tutorial, it seems I need to setup a class to be called from OWIN via an attribute:

Answer 1

In my case I have created a custom hub activator which uses a shared container between my app and signalR (by constructor injection) that way you´ll have single composite root for the whole application.

try the following:

public class CustomHubActivator : IHubActivator
    {
        private readonly Container _container;

        public MseHubActivator(Container container)
        {
            _container = container;
        }

        public IHub Create(HubDescriptor descriptor)
        {
            return _container.GetInstance(descriptor.HubType) as IHub;
        }
    }

register your custom hub activator when you´re bootstrapping your app (maybe the global.asax)

 GlobalHost.DependencyResolver.Register(typeof (IHubActivator),
                                                   () => new CustomHubActivator(Container));

that´s much simplier solution rather than to configure again the signalR dependencyResolver
