I know this topic is going on for a while and I walked into some kind of the same issue. So far I couldn't find a solution for me that keeps the whole thing together at one place so the code is still readable.

At creation of an user I want to have some fields set by the object itself via private setters, e.g. a GUID and Creation Date and not 'polluting' the constructor.

My User class:

public class User
{
    public static User Create(Action init)
    {
        var user = new User();
        user.Guid = Guid.NewGuid();
        user.Since = DateTime.Now;
        init(user);
        return user;
    }

    public int UserID { get; set; }

    public virtual ICollection Roles { get; set; }
    public virtual ICollection Widgets { get; set; }

    [StringLength(50), Required]
    public string Name { get; set; }
    [EmailAddress, Required]
    public string Email { get; set; }
    [StringLength(255), Required]
    public string Password { get; set; }
    [StringLength(16), Required]
    public string Salt { get; set; }

    public DateTime Since { get; private set; }
    public Guid Guid { get; private set; }
}

Calling code:

context.Users.Add(User.Create(c=>
{
    c.Name = "Name";
    c.Email = "some@one.com";
    c.Salt = salt;
    c.Password = "mypass";
    c.Roles = new List { adminRole, userRole };
}));
