We have now got a Codeplex project to serve you! Check out http://www.codeplex.com/vsdbpro, the first set of samples has been checked in.
This is a small WinForms application that lets you interactively look at the results of the Regex string data generator, below a snaphot.
I hope you find it useful, feel free to collaborate on these sample project, send suggestions or ask questions.
Oh by the way a happy New Year to all of you!
