Put Asp Net MVC Identity validation

Question

I tried to locate this doubt in the forum and could not find. I have an Asp Net MVC application that uses the Entity Framework with Identity to login. My client registration works perfectly, but I’m not able to validate two fields: Username and Login. I tried to locate where they are called, but from what I read on the net so far, it gets "encapsulated" and I couldn’t put the validations on them. I’d like to put a validation like that on them:

[Required]
    [StringLength(10, MinimumLength = 6)]
    public string Senha { get; set; }

The problem is that I am not able to find Username and Login. I could not find the Accountviewmodels.Cs that I was referred to on the net. Can someone please help me? I would just like to validate the Username and Login fields so that it is not possible to save the registration with them blank, as I did not find their location, I can not validate and the easiest way I found was as I reported in the code above.

To register a user, Identity in aspnet mvc 5 uses the class Registerviewmodel that’s in the archive Accountviewmodels.Cs inside the briefcase Models.

public class RegisterViewModel
{
    [Required]
    [EmailAddress]
    [Display(Name = "Email")]
    public string Email { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm password")]
    [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }
}

This is the class gets the email, password and password confirmation from the registration screen. Here you can customize the validations at will.
