login controller

public class logincontroller : controller {     private staunchcontext _context;     public logincontroller(staunchcontext context)     {         _context = context;     }      // get: /<controller>/     public iactionresult login()     {         return view();     }      [httppost]     public async task<iactionresult> login(userdetails users)     {         if (modelstate.isvalid)         {             var exist =await _context.userdetails.singleordefaultasync(x => x.email == users.email && x.password == users.password);             if ((exist!=null)&& exist.id > 0)             {                 tempdata["users"] = jsonconvert.serializeobject(exist);                 httpcontext.session.setstring("email", exist.email);                 return redirecttoactionpermanent("index", "search");             }             else             {                 modelstate.addmodelerror("loginerror", "invalid username or password");             }         }         return view(users);     } 

i believe default route login page. if change it, fix problem?

app.usemvc(routes => {     routes.maproute(         name: "default",         template: "{controller=home}/{action=get}/{id?}"); }); 

(make sure replace home & default page)
