Although that is still a blank window , I am working hard on that,AdvGen Contact Manager. I am aiming to use it for the contact management system in my fellowship. It will have a local database ,a nice WPF interface and 100% written in C#. I wish this xmas holidays, I will have more time to work on this project. That will be a tool for my fellowship.
(P.S. I wish I can get other groups in my church to use that!)
