Hi all,

I have a silly question. I would like to know if there is performance deference in these two quries:

var cObject = from cust in entities.Customer 
          where cust.id == cid
      select cust;

and

var cObject = entities.Customer.First( c=> c.id == cid);

My query return only one record as I am querying with the primary key. But do they make any difference?
