asp.net - cannot load SignalR hub script in Autofac -

i'm trying use signalr autofac dependency in application, have registered dependencies on run time causing error signalr dyanmic generated file hubs missing , without can't anything. i've searched internet couldn't find solution. please help.

config class:

[assembly: webactivatorex.preapplicationstartmethod(typeof(iocconfig), "registerdependencies")]  namespace rental.bootstrapper {     public class iocconfig     {         public static void registerdependencies()         {             var builder = new containerbuilder();             const string nameorconnectionstring = "name=defaultconnection";             builder.registercontrollers(typeof(mvcapplication).assembly);             builder.registerapicontrollers(typeof(webapiconfig).assembly);             builder.registerhubs(typeof(rentalhub).assembly);             //builder.registerinstance(typeof(startup));             builder.registermodule<autofacwebtypesmodule>();             builder.registergeneric(typeof(entityrepository<>)).as(typeof(irepository<>)).instanceperhttprequest();             builder.registergeneric(typeof(service<>)).as(typeof(iservice<>)).instanceperhttprequest();             builder.registertype(typeof(unitofwork)).as(typeof(iunitofwork)).instanceperhttprequest();             builder.register<ientitiescontext>(b =>             {                 var logger = b.resolve<ilogger>();                 var context = new rentalcontext(nameorconnectionstring, logger);                 return context;             }).instanceperhttprequest();             builder.register(b => nloglogger.instance).singleinstance();             builder.registermodule(new identitymodule());              var container = builder.build();              dependencyresolver.setresolver(new autofac.integration.mvc.autofacdependencyresolver(container));             globalconfiguration.configuration.dependencyresolver =                  new autofacwebapidependencyresolver(container);              var signalrdependencyresolver = new autofac.integration.signalr.autofacdependencyresolver(container);             globalhost.dependencyresolver = signalrdependencyresolver;                                           }     } } 

i suspect not autofac issue @ all. assume use mvc4, using owin default. owin has startup class, middleware , extensions must registered. normally, startup.cs class @ minimum, required signalr, contains this:

using microsoft.aspnet.signalr; using microsoft.owin; using owin;  [assembly: owinstartup(typeof(startup))] namespace mynamepace {     public class startup     {         public void configuration(iappbuilder app)         {             app.mapsignalr(new hubconfiguration             {                 enabledetailederrors = true             });         }     } } 

if @ mapsignalr method, find registers the"/signalr" route , missing, if understand question correctly:

/// <summary> /// maps signalr hubs app builder pipeline @ "/signalr". ///  /// </summary> /// <param name="builder">the app builder</param><param name="configuration">the <see cref="t:microsoft.aspnet.signalr.hubconfiguration"/> use</param> public static iappbuilder mapsignalr(this iappbuilder builder, hubconfiguration configuration) {   return owinextensions.mapsignalr(builder, "/signalr", configuration); } 

autofac signalr documentation has section owin startup, suggest there. has complete code startup.cs file includes autofac container initialization, registrations , owin-related code signalr.
