    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        List<ValidationResult> validationResults = new List<ValidationResult>();
        FileOptions fileOptions = new FileOptions()
        {
            FileTypes = new FileType[] {FileType.Jpeg,FileType.Jpg},
            MinSize = 124,
            MaxSize = Convert.ToInt32(AppSettings.GetValue("DemoSettings:MaxFileSize"))
        };

        ValidationResult minAgeValidationResult = validationContext.ValidateMinAge(nameof(DateOfBirth), 10, 0, 0);
        validationResults.Add(minAgeValidationResult);

        ValidationResult fileValidationResult = validationContext.ValidateFile(nameof(Photo), fileOptions);
