I'm trying to get the following to work on my machine but I get an error (Cannot

I have added the reference System.ServiceModel and the lines:
using System.ServiceModel;
using System.ServiceModel.Channels;
but I continue to get that error when trying to compile -- "Cannot
create an instance of the abstract class or interface 'System.ServiceModel.Channels.MessageHeader'"
I am using Microsoft Visual Studio 2008
Version 9.0.21022.8 RTM
Microsoft .NET Framework
Version 3.5 SP1
Professional Edition
Is there another reference I have to add? Or a dll to move over?
I wonder was the code above written for Framework 2.0 only?
Thanks for your help.
