hop of those help? The proper way would be to just depend on that service as part of your attribute adapter. So just add the additional dependency in its constructor:
public class InvalidIdAttributeAdapter : AttributeAdapterBase<InvalidIdAttribute>
    private readonly InvalidIdAttribute _attribute;
    private readonly IProductService _productService;

    public InvalidIdAttributeAdapter(InvalidIdAttribute attribute, IStringLocalizer stringLocalizer, IProductService _productService)
        : base(attribute, stringLocalizer)
        _attribute = attribute;
        _productService = productService;

    public override void AddValidation(ClientModelValidationContext context)
        var invalidIds = _productService.GetIds()…;

        // …
services.AddScoped<IValidationAttributeAdapterProvider, InvalidIdAttributeAdapterProvider>();

help you fix your problem Is it possible to implement client-site validation for custom ValidationAttribute, which is used in Class scope? For example my MaxLengthGlobal, which should assure global max limit for all input fields. , Nope, it's not possible. Sorry.

My undertsandng is that it will generate enough meta data for the client side script to automatically validate (using jquery.validate).

Validation type names in unobtrusive client validation rules must consist

I hope this helps you . I finally managed to solve this problem.
Below is the full solution. In short, if you have a ValidationRule that will be visited multiple times (in my case hundreds of times) you need to make sure the name stays unique for as long as the IIS session is active. In my case that is 24 hours.
const string Chars = "abcdefghijklmnopqrstuvwxyz";

var c = "";
if (count > 0)
    var p = 0;
    while (count / Math.Pow(Chars.Length, p) > Chars.Length)

    while (p > 0)
        var i = (int)(count / Math.Pow(Chars.Length, p));
        c += Chars[Math.Max(i, 1) - 1];
        count = count - (int)(i * Math.Pow(Chars.Length, p));
    var ip = Math.Max(Math.Min((count) % Chars.Length, Chars.Length - 1), 0);
    c += Chars[ip];

ASP.NET MVC ValidationAttribute causes invalid client side validation rules

I wish did fix the issue. I’m working on a ASP.NET MVC 5 Application. I’m using Attributes to validate my models (back- and frontend). , One way that i know is this:
      [Range(typeof(decimal), "0", "79228162514264337593543950335")]
      public decimal Amount { get; set; }
