How to display Entity C# validation error?

Question

.NET

There is a description of the user class and it describes the validation of its attributes.
For example:

public partial class User
    {
        [Required]
        [EmailAddress(ErrorMessage = "Email был неверно указан.")]
        public string Email { get; set; }
        [Required]
        [RegularExpression(@"\d", ErrorMessage = "Пароль был не верно указан.")]
        public string Password { get; set; }
    }
