System.DirectoryServices.AccountManagement won’t load from asp.net Core 2.0 (netcoreapp2.0) website

Referencing .net 4.5.1 framework class library from asp.net Core 2.0 (netcoreapp2.0), where class library references System.DirectoryServices.AccountManagement leads to receives FileNotFound exception.

Manual Repro

dotnet new aurelia npm install add new Utils .Net Framework 4.51 project (version doesn’t matter) add class below to Utils .Net Framework 4.51

    public class ActiveDirectory
    {
        public static List<string> GetGroupNames(string userName)
        {
            var result = new List<string>();

            if (string.IsNullOrEmpty(userName))
                return result;

            var domain = userName.Split('\\').FirstOrDefault();

            var pc = new PrincipalContext(ContextType.Domain, domain);
            var identity = UserPrincipal.FindByIdentity(pc, userName);
            if (identity != null)
            {
                var src = identity.GetGroups(pc);
                src.ToList().ForEach(sr => result.Add(sr.SamAccountName));
            }
            return result;
        }

    }

add Utils project reference to asp.net core app project update HomeController.cs

    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            var groups = ActiveDirectory.GetGroupNames(User.Identity.Name);

            return View();
        }
    }
