This topic describes new functionality in ADO.NET Data Services that is available as an update to the .NET Framework version 3.5 Service Pack 1. You can download and install the update from the Microsoft Download Center.

This example uses the GetContinuation method in a do…while loop to load Customers entities from a paged results from the data service.

// Create the DataServiceContext using the service URI.
NorthwindEntities context = new NorthwindEntities(svcUri);
DataServiceQueryContinuation<Customers> token = null;
int pageCount = 0; 

    // Execute the query for all customers and get the response object.
    QueryOperationResponse<Customers> response =
        context.Customers.Execute() as QueryOperationResponse<Customers>;

    // With a paged response from the service, use a do...while loop  
    // to enumerate the results before getting the next link. 
        // Write the page number.
        Console.WriteLine("Page {0}:", pageCount++);

        // If nextLink is not null, then there is a new page to load. 
        if (token != null)
            // Load the new page from the next link URI.
            response = context.Execute<Customers>(token)
                as QueryOperationResponse<Customers>;

        // Enumerate the customers in the response. 
        foreach (Customers customer in response)
            Console.WriteLine("\tCustomer Name: {0}", customer.CompanyName);

    // Get the next link, and continue while there is a next link. 
    while ((token = response.GetContinuation()) != null);
catch (Exception ex)
    throw new ApplicationException(
        "An error occurred during query execution.", ex);
