ServiceStack IAuthSession empty after authentication with FacebookAuthProvider -

i'm trying user data through iauthsession after doing authentication facebook, when try user request.getsession(true) returns authusersession (implements iauthsession) partial subset of data following:

i'm trying use in service method

[clientcanswaptemplates]         [defaultview("dashboard")]         public dashboardresponse get(facebookrequest userrequest)         {             var user1 = request.getsession(true);             return new dashboardresponse();          } 

i've added auth providers apphost follows:

 plugins.add(new authfeature(() => new authusersession(), new iauthprovider[] {                 new facebookauthprovider(appsettings),                  new twitterauthprovider(appsettings),                  new basicauthprovider(appsettings),                  new googleopenidoauthprovider(appsettings),                  new linkedinauthprovider(appsettings),                  new credentialsauthprovider()             })); 

as far know facebookauthprovider should fill iauthsession following information:

usersession.facebookuserid = tokens.userid ?? usersession.facebookuserid; usersession.facebookusername = tokens.username ?? usersession.facebookusername; usersession.displayname = tokens.displayname ?? usersession.displayname; usersession.firstname = tokens.firstname ?? usersession.firstname; usersession.lastname = tokens.lastname ?? usersession.lastname; usersession.primaryemail = tokens.email ?? usersession.primaryemail ?? usersession.email; 

what step missing?

i in similar situation issue based answer decided try out, , worked.

the difference i'm using simple injector , have consider register dependency singleton easier way me register this:

simpleinjectorcontainer.registersingle<icacheclient>(()=>new memorycacheclient());
