I have something like this:
var itemsInCart = from o in db.OrderLineItems
where o.OrderId == currentOrder.OrderId
select new { o.OrderLineItemId, ..., ..., o.WishListItem.Price}
is there any way to do a
itemsCart.Sum() //not sure what to pass into the function
to get the sum of o.WishListItem.Price or do i have to get another iQueryable< T> from the database with group ... into?
