Return Tuple from EF select

How can I retrieve Tuples at Select using EF4?

        var productCount = (from product in context.products
                    select new Tuple<Product, int>(product, products.Orders.Count));

Or

        var productCount = (from product in context.products
                    select Tuple.Create(product, products.Orders.Count));

Entity framework says that cant use not empty construct开发者_Python百科or for first case, and not recognize Tuple.Create method for second.

How about switching to LINQ-to-Objects for the projection:

var productCount = from product in context.products
                select new {Product = product, Count = products.Orders.Count };
var final = from item in productCount.AsEnumerable()
            select Tuple.Create(item.Product, item.Count);

Try

 var productCount = from product in context.products 
                    select new { product, Count = products.Orders.Count }; 

This will return an anonymous type which is very close to a tuple http://msdn.microsoft.com/en-us/library/bb738512.aspx
