Descrizione

I have a string array field which validates not only the length of the array, but the length of the strings in the array as well:

"Tags": {
      "type": "array",
      "minItems": 1,
      "maxItems": 16,
      "items": {
        "type": "string",
        "minLength": 1,
        "maxLength": 3
      }
    },

However, when converted to a C# OM, the per-item validation gets lost:

[Newtonsoft.Json.JsonProperty("Tags", Required = Newtonsoft.Json.Required.DisallowNull, NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore)]
[System.ComponentModel.DataAnnotations.MinLength(1)]
[System.ComponentModel.DataAnnotations.MaxLength(16)]
public System.Collections.Generic.ICollection<string> Tags { get; set; }

I don't have a bright idea on how this validation criteria could live in the .NET world, it's possible that there's no way to currently phrase that using the DataAnnotations, but I'm hoping to be surprised!
