I just published an article on CodeProject called ‘Creating the Same Program in Windows Forms and WPF‘. I think it provides some interesting information on the similarities and differences of WinForms and WPF, by showing how to implement the same simple application using both platforms. It is not a means of parading WPF and shunning WinForms. I tried to be as objective and down-to-earth as possible when discussing the relative merits of the two platforms.
