hello,
I try to compile the sample in chapter 1 in "OpenAccess - MadeEasy" :

    
            using (IObjectScope scope = ObjectScopeProvider1.ObjectScope()) 
        
                        { 
        
                            scope.Transaction.Begin(); 
        
                            // add a new customer 
        
                            Customer newnewCustomer = new Customer(); 
        
                            newCustomer.CustomerID = "A" + System.DateTime.Now.ToString("hmsfff"); 
        
                            newCustomer.CompanyName = "New Customer"; 
        
                            scope.Add(newCustomer); 
        
                            // get first customer using LINQ and modify 
        
                            Customer firstCustomer = 
        
                            scope.Extent<Customer>().Take(1).Single(); 
        
                            firstCustomer.CompanyName = 
        
                            "Company " + DateTime.Now.ToString("hmsfff"); 
        
                            scope.Add(firstCustomer); 
        
                            // use LINQ to retrieve customer ID's starting with "E" 
        
                            var results = 
        
                            from c in scope.Extent<Customer>() 
        
                            where c.CompanyName.StartsWith("E") 
        
                            select c; 
        
                            // delete "E" customers from the database 
        
                            foreach (Customer cust in results) 
        
                            { 
        
                                foreach (Order order in cust.Orders) 
        
                                { 
        
                                    foreach (OrderDetail detail in order.OrderDetails) 
        
                                    { 
        
                                        scope.Remove(detail); 
        
                                    } 
        
                                    scope.Remove(order); 
        
                                } 
        
                                scope.Remove(cust); 
        
                            } 
        
                            scope.Transaction.Commit(); 
        
                        } 
        
                        Console.Write("Done"); 
        
                        Console.ReadLine(); 
        
                    }

Build error :

Error 2 'Telerik.OpenAccess.IObjectScope' does not contain a definition for 'Extent' and no extension method 'Extent' accepting a first argument of type 'Telerik.OpenAccess.IObjectScope' could be found (are you missing a using directive or an assembly reference?)

Please help...
