>Hmm... I think what I'm not getting is what the .XSD is used for. I had assumed it was used by the IDE for creating the DataSet.Designer.cs file, are you using the .XSD at run time in your programs?

No, you're right. The .xsd is used by the IDE to generate a Typed DataSet. I was just talking about another way of creating the .xsd (programmatically with a utility). End result is the same.

>I appreciate your help on this, there is so much to understand when you are getting ready to write decent sized apps in a new language. Understanding the basics of how to lay things out in the new system really helps!

No problem, you're welcome. Starting out with the correct architecture right from the beginning certainly makes developing a new app much easier! =0)
