c# - SignalR and OwinContext = System.ObjectDisposedException -

-

i have asp.net application using signalr. when try call owincontext (in signalr hub), got system.objectdisposedexception.

i use owincontext :

context.request.gethttpcontext().getowincontext().getusermanager<applicationusermanager>();

here startup class:

        app.usecookieauthentication(new cookieauthenticationoptions         {             authenticationtype = defaultauthenticationtypes.applicationcookie,             authenticationmode = authenticationmode.active,             provider = new cookieauthenticationprovider             {                 onvalidateidentity = securitystampvalidator.onvalidateidentity<applicationusermanager, applicationuser>(                     validateinterval: timespan.fromminutes(30),                     regenerateidentity: (manager, user) => user.generateuseridentityasync(manager))             },             cookiename = "aspnetidentityauth",             cookiedomain = configurationmanager.appsettings["cookiedomain"]         });

all works fine on w7 dev machine iisexpress. problem appear on w2012r2 server iis8.5.
