Question

I want to use my custom User table in MVC 4 code first application. I defined advance User table in my database context:

public class MyDatabase : DbContext
    {
       public DbSet<User> UserSet { get; set; }
       public DbSet<News> NewsSet { get; set; }
       ...
    }

Model is like:

 public class User 
    {
        [Key]
        public int Id{ get; set; }
        public string UserName { get; set; }
        public string Password { get; set; }
        public string Name { get; set; }
        public string SurName { get; set; }
        ...
    }

When application start, it calls this:

WebSecurity.InitializeDatabaseConnection("MyDatabase", "Users", "Id", "UserName", autoCreateTables: true);

In controller I use Add(entity) to save user entity. After saving I want to log in user. But it does not work:

    [HttpPost]
    public ActionResult Register(User user)
    {
     var result =  MyService.SaveUser(user);
     WebSecurity.Login(result.UserName, result.Password, true);
     return RedirectToAction("Index", "Profile", new { id = result.Id });
    }

After saving user, it’s data stored in my database, but it can not log in. How should I do?

Edit:

Is it right to save User entity with my business method? Or I must do it only with
WebSecurity.CreateUserAndAccount()?

If I can use my own save method, how to save password in database?

You could just use forms authentication directly.

 [HttpPost]
    public ActionResult Register(User user)
    {
     var result =  MyService.SaveUser(user);
     SignIn(result.Id, "");
     return RedirectToAction("Index", "Profile", new { id = result.Id });
    }


public void SignIn(string accountId, string roles)
            {
                var authTicket = new FormsAuthenticationTicket(
                    1,
                    accountId,
                    DateTime.Now,
                    DateTime.Now.AddMinutes(20),
                    false,
                    roles
                    );

                string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
                var authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);

                HttpContext.Current.Response.Cookies.Add(authCookie);
            }

Here is a user class that will help you with password issue. It relies on BCrypt

 public class UserAccount
    {
        public string Id { get; set; }
        public string Username { get; set; }
        public string Email { get; set; }

        public string Password
        {
            get { return PasswordHash; }
            set { PasswordHash = HashPassword(value); }
        }

        public string PasswordHash { get; private set; }

        public List<string> Roles { get; set; }

        public string AuthenticationRoles
        {
            get { return Roles == null ? "" : String.Join(",", Roles.Select(x => x.ToString())); }
        }

        public bool IsActive { get; set; }

        public string Name { get; set; }

        public bool PasswordIsValid(string password)
        {
            bool matches = BCrypt.Net.BCrypt.Verify(password, Password);
            return matches;
        }

        private string HashPassword(string value)
        {
            return BCrypt.Net.BCrypt.HashPassword(value);
        }
    }
