Bill ,

Do you mean the a CS file was generated when you generated a dataset in Visual Studio from your XSD (XML Schema) File? This is the .NET DataSet that Visual Studio generates for you, so you can use and DataSet in code to represent the structure of the XML files that you will be dealing with.

It isn't a Business class, it is .NET class that can be used to access and manipulate the XML data as you are using it.
