Hi guys,,l'm learn how to create login without EF in VS 2019 MVC. The login Controller can not return RedirectToAction("Index", "Home"); although the username and password has been entered correctly. I want if user entered correct username and password or success login will redirect to AdminDashboard.
 
this is the login.cshtm
  1. @model AdminLTEMvc.Models.LoginViewModel
