I tried DLinq code created by Marc and got NRE in ToList() line.
Any idea what causes this ?

Andrus.

Code:

Northwind db = CreateDB();
var orders = db.GetTable<Order>().ToArray().AsQueryable();

var query = from order in orders
                       select new
                       {
                           OrderID = order.OrderID,
                           Customer = new
                           {
                               ContactName = order.Customer.ContactName,
                               ContactTitle = order.Customer.ContactTitle
                           }
                       };
var list = query.ToList();

result:

System.NullReferenceException was unhandled
 Message="Object reference not set to an instance of an object."
