Code First Model Definition - asp.net

Question

I have the following models,do I define it Ok?
User is the main Entity and can have 0..1 to * (zero /one to many relationship ) address.
2.User can have have 0..1 to 1 (one to one userPass )
This is the main table
public class User
{
[Key]
[Required]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public string UserId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string Phone { get; set; }
public string PhoneWork { get; set; }
public string WorkingAt { get; set; }
public virtual UserPass UserPass { get; set; }
public virtual ICollection<Address> Addresses { get; set; }
}
public class ConfigModelDbContext : DbContext
{
public DbSet<User> User { get; set; }
public DbSet<Address> Addresses { get; set; }
public DbSet<UserPass> UserPasses { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
modelBuilder.Entity<User>()
.HasOptional(c => c.Addresses).WithRequired(addresses => new User());
modelBuilder.Entity<User>()
.HasOptional(c => c.UserPass).WithRequired(pass => new User());
}
}
Address Class
public class Address
{
[Key]
[ForeignKey("User")]
public string UserId { get; set; }
public string UserAddress { get; set; }
}
Userpass class
public class UserPass
{
[Key]
[ForeignKey("User")]
public string UserId { get; set; }
public string User { get; set; }
public string Password { get; set; }
}
i also created classes same as above but can it create relationship directly on database table?

Answer 1

at first I offer you to use data annotation instead of fluent api always.
then correct AddressClass like below:
public class Address
{
[Key]
public int Id { get; set; }
[ForeignKey("UserId")]
public User User { get; set; }
public string UserId { get; set; }
public string UserAddress { get; set; }
}
This will create Ralationship.
