My latest Data Points column is now online and in print in the October 2009 issue of MSDN Magazine. The column’s title is “Validation with Silverlight 3 and the DataForm” which focuses on the validation features in Silverlight 3. This includes the DataForm, the validation XAML binding attributes, and the DataAnnotations.
