Good evening! I'm having a problem in my project where I'm trying to validate with date annotations and it's working, I just register in the database if I answer the validations, but the problem is that the messages I put to display along the date annotations do not work and I do not have idea of why this is happening, I have already looked at several codes and is identical but my valid but does not display the message. Someone help me please!

Controller:

using System;

using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using ProjectInfo.ViewModels; using ProjectDeInovacao.Models; using ProjectInfo.Classes;

namespace ProjectInnovative.Controllers { public class HomeController: Controller {

    CadastroBLL bll = new CadastroBLL();
    [HttpGet]
    public ActionResult Login()
    {
        return View();
    }
    // instancia  e  manda  valores  para  variaveis 
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Login(Cadastro model)
    {
        if (ModelState.IsValid)
        {

            ViewData["Nome"] = model.Nome;
            ViewData["Email"] = model.Email;
            ViewData["Senha"] = model.Senha;
            bll.cadastrar(model);
            ModelState.Clear();
            return View(model);
        }
        else
        {
            return View("Login");
        }

    }
    public ActionResult Index()
    {
        ViewBag.Title = "Amorelli - Home";
        return View();
    }
    public ActionResult Carrinho()
    {
        ViewBag.Title = "Amorelli - Carrinho";
        return View();
    }
}

}

Model:

using System;

using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations;

namespace ProjectInnovative.Models { public class Registration { private string name; [Required (ErrorMessage="Required to enter name")] public string Name { get {return name; } set {name = value; } } private string email; [Required (ErrorMessage="Required E-mail")] [RegularExpression (". + \ @. + \ .. +", ErrorMessage="The E-mail entered is not valid")] public string Email { get {return email; } set {email = value; } } private string password; [Required (ErrorMessage="Required to enter a password")] [DataType (DataType.Password)] [StringLength (20, MinimumLength = 8)] public string Password { get {return password; } set {password = value; } } } }

View: @modelModels.CadastroDevelopment.model @ { ViewBag.Title="Amorelli - Login"; }
