            .NotEmpty()
            .WithMessage("{PropertyName} is required !")
            .MinimumLength(5)
            .WithMessage("Minimum length for {PropertyName} is {MinLength} !");

            .NotEmpty()
            .WithMessage("{PropertyName} is required !")
            .MinimumLength(5)
            .WithMessage("Minimum length for {PropertyName} is {MinLength} !");
