Using context As New AdventureWorksEntities()
Dim queryString As String = "SELECT VALUE product FROM AdventureWorksEntities.Products AS product"
Dim productQuery As New ObjectQuery(Of Product)(queryString, context, MergeOption.NoTracking)
Dim queryString2 As String = "SELECT VALUE product FROM AdventureWorksEntities.Products " & _
" AS product WHERE product.ProductID < @productID"
Dim productQuery2 As New ObjectQuery(Of Product)(queryString2, context, MergeOption.NoTracking)
productQuery2.Parameters.Add(New ObjectParameter("productID", productID))
Dim productQuery3 As ObjectQuery(Of Product) = productQuery.Except(productQuery2)
Console.WriteLine("Result of Except")
Console.WriteLine("------------------")
' Iterate through the collection of Product items
' after the Except method was called.
For Each result As Product In productQuery3
