c# - LogIn in Asp.Net Identity project -


i'm doing web application based on asp.net, , login system based on identity framework. problem i'm getting bit strange.

i run application takes me login page, login (and redirected homepage) if logout , try login again keeps giving me login page instead home page, if second login breakpoint in async call , go step step login done , i'm redirected home page.

the code is:

[httppost]         [allowanonymous]         public async task<actionresult> login(loginmodel model)         {             if (!modelstate.isvalid)             {                 return view();             }          //breakpoint          var user = await usermanager.findasync(model.email, model.password);              if (user != null)             {                 var identity = await usermanager.createidentityasync(                     user, defaultauthenticationtypes.applicationcookie);                  signin(user);                  return redirect(getredirecturl(model.returnurl));             }              // user authn failed             modelstate.addmodelerror("", "invalid email or password");             return view();         }       private string getredirecturl(string returnurl)     {         if (string.isnullorempty(returnurl) || !url.islocalurl(returnurl))         {             return url.action("index", "home");         }          return returnurl;     }      private async task signin(identityuser user)     {         var identity = await usermanager.createidentityasync(             user, defaultauthenticationtypes.applicationcookie);         getauthenticationmanager().signin(identity);     }      private iauthenticationmanager getauthenticationmanager()     {         var ctx = request.getowincontext();         return ctx.authentication;     }      public actionresult logout()     {         var ctx = request.getowincontext();         var authmanager = ctx.authentication;         session.abandon();          authmanager.signout("applicationcookie");         return redirecttoaction("login", "login");     }
