Generic Local Function and List

Question

Thank you for reading! I'm getting a list of objects (from a dbcontext), then I created a method to pass this list to a Local Function, the method accepts the list but when I try to loop, instead of being able to show the content of my object members I get an error saying: "'T' does not contain a definition for 'Id' and no accessible extension method 'Id' accepting a first argument of type 'T' could be found (are you missing a using directive or an assembly reference?) " And this problem is not only with Id, I can't access any of the properties, please check the code: would you please help me find what I am missing? thank you for your advice.

public IActionResult Racks()
        {

            List<OldRackAustin> mylist = db.OldRacksAustin.ToList<OldRackAustin>();

            ProcessMyList(mylist);

            void ProcessMyList<T>( List<T> list)
            {

                foreach (T item in list)
                {
                    Debug.WriteLine(item.Id);  /* PROBLEMATIC LINE */
                }

            }

            return Json("done");
        }

 And the DBcontext entity (object) looks like...

 

[Table("OLD-Racks-Austin")]
    public class OldRackAustin
    {
        [Key]
        public int Id { get; set; }
        public string Rack_Type { get; set; }
        public string Serial_Number { get; set; }
        public short Pages { get; set; }
        public int? Rack_Capacity { get; set; }
        public string Status { get; set; }
        public string Type { get; set; }
        public string Subtype { get; set; }

}
