如何在MVC 5应用程序中配置Autofac和SignalR

我正在尝试配置MVC 5应用程序以使用SignalR 2.2.x并将服务注入到我的NotificationsHub。我们正在将Autofac用于MVC，但是我不确定如何正确配置它。存在NuGetAutofac.Integration.SignalR (3.0.2)和的Autofac文档Autofac.Integration.Mvc (3.3.4)。

到目前为止，我正在通过以下方式注册集线器：

ContainerBuilder builder = new ContainerBuilder();

// Register MVC controllers.
builder.RegisterControllers(typeof(MvcApplication).Assembly);

builder.RegisterType<ServiceForSignalRHub>().AsImplementedInterfaces();
builder.RegisterType<...>().AsImplementedInterfaces();

builder.RegisterHubs(Assembly.GetExecutingAssembly());

IContainer container = builder.Build();

DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

但是.SetResolver(...)，由于MVC和SignalR集成软件包中都存在对它的调用，因此模棱两可。怎么办？我无法确认服务的构造器注入是否适用于我正在使用的集线器。

我可以用Autofac配置MVC5。我迷路的是如何使用Autofac Signal集成NuGet对SignalR进行相同的操作。请看下面。

这是我的入门班：

public partial class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var defaultFactory = LogManager.Use<DefaultFactory>();
        defaultFactory.Directory("@D:\\NServiceBus\\ );
        defaultFactory.Level(LogLevel.Debug);

        var container = ConfigureAutofac(app);

        ConfigureServiceBus(container, app);

        app.UseAutofacMiddleware(container); // REGISTER WITH OWIN
        app.UseAutofacMvc();

        ConfigureAuth(app);

        GlobalConfiguration.Configuration.UseSqlServerStorage("hangfire");

        ConfigureSignalR(app);
    }
}

这是我配置SignalR的部分：

public partial class Startup
{
    public void ConfigureSignalR(IAppBuilder app)
    {
        var builder = new ContainerBuilder();

        builder.RegisterHubs(Assembly.GetExecutingAssembly()).PropertiesAutowired();
        builder.RegisterType<MaintenanceService>().As<IMaintenanceService>().PropertiesAutowired();

        var container = builder.Build();
        //var container = new AutofacContainer().Container;

        var resolver = new AutofacDependencyResolver(container);

        // Any connection or hub wire up and configuration should go here
        app.MapSignalR(new HubConfiguration
        {
            Resolver = resolver,
            EnableJSONP = true,
            EnableDetailedErrors = true,
            EnableJavaScriptProxies = true
        });

        builder.RegisterInstance(resolver.Resolve<IConnectionManager>());
    }
}

如何正确地做到这一点？
