I just found out that my changes to the article and code for Silverlight 2 RTW are now live. The article makes the small change that it no longer requires you to use EdmGem to build your proxy (using the Service Reference instead).  I’ve also updated the code example to be compatible with .NET 3.5 SP1 and Silverlight 2.

In case you’re not familiar with this MSDN Magazine article, it covers how to implement data access using ADO.NET Data Services and Silverlight 2 including reading and writing data.  Let me know if you have questions about it.
