>Thank you. You make a good point that I was trying to say to Mike. He was trying to convince me that using WinForms is a waste of time. I disagreed saying that if/when I go with WPF I will still need to write BIZ classes, DAL classes, manipulate ADO.NET and C# and ADO.NET knowledge will be helpful.

I guess I could have worded it better. I meant the GUI aspect of WinForms, not the code part.
