title: Linq-to-SQL same OnLoaded of all entities
body: <p>All my Linq-to-SQL-generated classes are inherited from the single base class and I want to implement identical 'on loaded' verification logic for all entities in my database. But I do not see any event in DataContext I can use for that purpose. The only solution I found is to put <code>Verify()</code> call to every partial <code>OnLoaded</code> method. But there is a high chance that I forget to call it somewhere. Is there any more elegant and unified solution?</p>
