Я должен упустить что-то очень важное в концепции, чтобы получить это
ошибка, поэтому любая помощь приветствуется.
я получаю
----> System.Data.SqlClient.SqlException: невозможно обновить личность
столбец «ProductID».
когда я запускаю это
var tblEvent = session.Load<TblEvent>(17);
tblEvent.Code+= " - test update";
using (var tran = session.BeginTransaction())
{
session.SaveOrUpdate(tblEvent);
tran.Commit();
}
Загрузка работает правильно, и я могу проверить все свойства, но обновление не удается.
Вот файл сопоставления
