You're going to have to do something like this for the child records: http://stackoverflow.com/questions/27176014/how-to-add-update-child-entities-when-updating-a-parent-entity-in-ef — Steve Greene, Mar 10 '16 at 16:02

You can do this to:

db.Entry(record).state = EntityState.Modified;
db.SaveChanges();
