Using Simple Injector with SignalR

Well, I tried yesterday and I’ve found a solution.
According to me, the only moment where I want dependency injection in SignalR is for my hubs: I don’t care about how SignalR is working inside !
So instead of replacing the DependencyResolver, I created my own implementation of IHubActivator :

public class SimpleInjectorHubActivator : IHubActivator
{
    private readonly Container _container;

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

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

That I can register like this (in Application_Start) :

var activator = new SimpleInjectorHubActivator(container);
GlobalHost.DependencyResolver.Register(typeof(IHubActivator), () => activator);
RouteTable.Routes.MapHubs();
