Thank you for the feedback :) First, I have just fixed this by configuring with the machine name instead of the IP address. That is a kind of workaround about that :) To answer your question, there is no use for dual nic actually. I was testing my application on a new machine and I got the error (since it does have 2 network cards) so I was figuring out if I could manage that :)

Taking your example; there's a difference in getting an order in the properties and getting an order in the items within the collection. You can change the order of the properties by adding those tags to the Person class. The collection would be serialized using that information. Implementing ISerializable[^] or even IXmlSerializable[^] would be more appropriate for complexer structures. That way you can control the order of the properties and the data. There's a really nice CodeProject article on IXmlSerializable here[^]. Good luck :) I are Troll :suss:
