This method is used to create a new copy of a message ready for sending. This static method is used to create a new copy of message ready for sending.

When working with JSON messages use the CreateMessage(MessageVersion, String, Object, XmlObjectSerializer) method, the CreateMessage(MessageVersion, String, Object) method does not work with JSON messages.
