Application: .net core 3.1,
OS:win 10,
VS :2019,
SqlTableDependency:8.5.8
Sql Server :10.50.1600.1.
this is my test code:

internal class Program
    {
        private static string _con = "data source=.; initial catalog=exam; integrated security=True";

        public static void Main()
        {
            using var dep = new SqlTableDependency<TB_VERSION>(_con, "TB_VERSION");
            dep.OnChanged += Changed;
            dep.Start();

            Console.WriteLine("Press a key to exit");
            Console.ReadKey();

            dep.Stop();
        }

        public static void Changed(object sender, RecordChangedEventArgs<TB_VERSION> e)
        {
            var changedEntity = e.Entity;

            Console.WriteLine("DML operation: " + e.ChangeType);
            Console.WriteLine("VERSION_ID: " + changedEntity.VERSION_ID);
            Console.WriteLine("VERSION_NO: " + changedEntity.VERSION_NO);
            Console.WriteLine("VERSION_CONTENT: " + changedEntity.VERSION_CONTENT);
            Console.WriteLine("VERSION_DATE: " + changedEntity.VERSION_DATE);
        }
    }

    public class TB_VERSION
    {
        public int VERSION_ID { get; set; }

        public string VERSION_NO { get; set; }

        public string VERSION_CONTENT { get; set; }

        public DateTime VERSION_DATE { get; set; }
    }

I had the same issue :“User without permissions.” but when I change my connectionString from this "Data Source=.;Initial Catalog=skynetdemo;User Id=sa; Password=pa$$word123; Trusted_Connection=True; MultipleActiveResultSets=true" to this "Data Source=CYB345-SOFT-01;Initial Catalog=skynetdemo;User Id=sa; Password=pa$$word123;" it work fine
