I bought a book by Papa called Data Driven Services for Silverlight2
that discusses setting up a web service for SL, and I was able to set
up and consume a simple web service. Thanks to you and A.G. of this
thread.

But I stand by my statement that XML is a cheap and easy way to mimic
a database. For example, nearly every example I see uses XML or hard
coded values, not a SQL query and a dB, to populate a list, GridView /
DataGrid, or combo box for example.
