entity .ToList() generates a System.OutOfMemoryException

Question

I have a table with half a million rows. I need to update every single row but the ToList() fails:

List allContacts = objDatabase.Contacts.ToList         


        

Answer 1

How about

IEnumerable allContacts = objDatabase.Contacts.AsEnumerable();

Never convert allContacts to a list. Just use is like an enumerator and apply Foreach loop to access each contacts.
