How do I clone an POCO Entity using CF?

How do I clone an POCO Entity when using DF Code First

Ok, in my abstract EntityBase I can try to implement ICloneable
but the methods I have found use serialisation, which when I mark the POCO as [Serializable], DF stops working!

Suggestions?
Thanks
John

I seem to have it with

            DataContractSerializer serializer = new DataContractSerializer(dfclone.GetType());
            XDocument document = new XDocument();
            using (XmlWriter xmlWriter = document.CreateWriter())
            {
                serializer.WriteObject(xmlWriter, dfclone);
            }
            var xmldoc = document.Root.ToString();

But XML has the EntityAspect present.
Will it always be between  <AAAA_EntityAspectForSerialization ></> so I can remover from XML?

thanks
