Have you worked through the steps thereafter?
You will need to go through the sample completely
Tip: At the stage you mentioned, you are looking at the XML structure. You will notice that there are changes to the structure from the previous section.
Background: Reflection is used to de/serialize the data. This means that if you add a Property to the class, you will see it in the structure.
I hope this helps.
