DataConnection.OnEntityCreated not called

Hi, I’m trying to use OnEntityCreated event. This is my C# code:

        private static void Main()
        {
            DataConnection.DefaultSettings = new MySettings();
            Configuration.Sql.GenerateFinalAliases = true;

            using var db = new WipDB("Wip");
            db.OnEntityCreated += (e) => Console.WriteLine(e.Entity.GetType().Name);

            var result = from ncCode in db.NcCode
                         join ncGroupMember in db.NcGroupMember
                         on ncCode.Handle equals ncGroupMember.NcCodeOrGroupGbo
                         where
                             ncGroupMember.NcGroupBo == "NCGroupBO:" + ncCode.Site + ",CATAN_AUTO" ||
                             ncGroupMember.NcGroupBo == "NCGroupBO:" + ncCode.Site + ",CATAN_MAN" ||
                             ncGroupMember.NcGroupBo == "NCGroupBO:" + ncCode.Site + ",CATAN_ALL"
                         select new AllowedNcCodeOutput { NcCodeBo = ncCode.Handle, NcCode = ncCode.NcCodeColumn, NcCodeDescription = ncCode.Description };

            var sql = result.ToString();
            Console.WriteLine(sql);
            var resultItems = result.ToList();
        }

The issue is that Console.WriteLine(e.Entity.GetType().Name is never called even if result.ToList() contains more than 7000 items. I’m expecting that OnEntityCreated will be raised for each entity of type AllowedNcCodeOutput that is created by the query. Am I wrong?

Thank you!

Yes, You give me better idea:

public static IEnumerable<T> AsChecked<T>(this IEnumerable<T> source)
{
    foreach (var item in source) 
    {
        /// run validator
       yield return item;
    }
}

Thank you for let me find a different way to solve my issue: IQueryable inherits IEnumerable and I can change the entities one by one using yield keyword. I want to avoid to allocate all entities in a list using ToList() before memory compression. The only drawback is that I need to change every query instead to implement a single event. Please feel free to close this issue if you want.

Thank you
