c# - Authenticate SignalR from MVC Controller -

i learning asp.net identity , signalr among other stuff. able create own authentication system using custom implementation of identity. trying authenticate user signalr before calling overridden onconnected.
after user gets authenticated using cookie authentication, [system.web.mvc.authorize] attribute passes succesfully, while [microsoft.aspnet.signalr] attribute tells me user has not authenticated yet.

//this authorize method: [httpget] public actionresult authorize() {     authenticationmanager.signin(new claimsidentity(new claimsprincipal(user).claims.toarray(), "bearer"));     return new emptyresult(); }  //this cookieauthenticationoptions app.usecookieauthentication(new cookieauthenticationoptions {     authenticationtype = defaultauthenticationtypes.applicationcookie,     loginpath = new pathstring("/account/login"),     provider = new cookieauthenticationprovider() });  //on hub public override task onconnected() {     string username = context.user.identity.name; //user null? } 

what missing here? have googled time , i'm not able find anything, not idea on how authenticate signalr.

most you're mapping signalr before authentication, must map signalr after authentication:

public void configuration(iappbuilder app) {          app.usecookieauthentication(new cookieauthenticationoptions         {             authenticationtype = defaultauthenticationtypes.applicationcookie,             loginpath = new pathstring("/home/index")         });          //...          app.mapsignalr();     }
