Mvc (asp.net ve sql ile)proje login ekranı hatası

Merhaba MVC login sayfası yapmaya çalışıyorum ve veri tabanındaki tablomda tuttuğum username ve password’u girip giriş yap dediğimde aşağıdaki resimdeki hata karşıma çıkıyor nasıl çözebilirim?
Not= Kodlarımı aşağıya ekliyorum.


  1. login.cshtml Sayfası
@{
    ViewBag.Title = "Login";
    Layout = "~/Views/_LayoutPage1.cshtml";
}
