        await _context.TableHpls.AddAsync(tableHpl);
        return tableHpl.Hplid;
    }

any help will be highly appreciated

Answer 1

replace

 await _context.TableHpls.AddAsync(tableHpl);

with this

 _context.TableHpls.Add(tableHpl);
await _context.SaveChangesAsync();

And I think you have to add some validation too:

 TableHpl tableHpl = new TableHpl
        {
            TabloTitle = addHealthPlaceViewModel.TabloTitle,
            Address = addHealthPlaceViewModel.Address,
            Services = addHealthPlaceViewModel.Services,
            Others = addHealthPlaceViewModel.Others,
            Personels = addHealthPlaceViewModel.Personels,
            CityCode = addHealthPlaceViewModel.CityCode,
            Recid = addHealthPlaceViewModel.Recid,
            Telegram = addHealthPlaceViewModel.Telegram,
            Email = addHealthPlaceViewModel.Email,
            Website = addHealthPlaceViewModel.Website,
            Instagram = addHealthPlaceViewModel.Instagram,
            PlaceCode = addHealthPlaceViewModel.PlaceCode
        };
if (addHealthPlaceViewModel.Hplphones!=null &&
     addHealthPlaceViewModel.Hplphones.Count > 0
{
 var tableHplphones = new List<TableHplphone>();

   foreach(var phone in addHealthPlaceViewModel.Hplphones)
     {
     
             tableHplphones.Add(  new TableHplphone
                {
                    Mobile = item.Mobile,
                    OfficePhone = item.OfficePhone
                }
           );
      }

tableHpl.TableHplphones=tableHplphones;
}
