Still researching, but if I had to guess, I'd think that I would use xmlReader and xmlWriter to do this. However, it doesn't give me any examples of how to access the file on my server, it just says "Store data to and retrieve data from isolated storage using Silverlight" which I think saves it to the user's computer.

It's giving me the impression that you can read or write to actual files on the server, is this true? If so, is it possible to embed the file within the application and use it that way somehow??
