> Pro tips : the ErrorMessage property of Validation attributes support the string format and can be mixed with the DisplayAttribute, it can be useful for generic validation.
>
> For exemple you can define
> ```
> [Display(Name = "My Property")]
> [StringLength(20, ErrorMessage = "field {0} max length is {1}")]
> String MyProperty { get; set; }
> ```
> And the validation will show "field My Property max length is 20".
