title: WCF XmlNode : Can't serialize
body: <p>I am rewriting a legacy asp.net web service (.asmx) in WCF. The legacy service exposed a method argument of type XmlNode. Seems like in WCF the XmlNode type cannot be serialized. If i try to change the arg to a string on the service side the consumer (.net class library service host wrapper) which is expecting XmlNode complains and does not execute successfully. I cannot change the service host. Any insight?</p>
