To cut a long story short, even though I've used .NET since the first beta (in 1999), I never got around to using Winforms - no, really! I have developed winforms apps in VB6 and swing apps in Java, just never got round to writing a C# Winforms app... To cut a long story short, I decided to write a little application leveraging a web service to monitor hits on this site (no reason, just a cool little web service with vaguely interesting data) , so I've picked up quite a few books on Winforms programming - well, 5...I have a book 'issue'. The best one I've found, both in terms on pure information and readability is Windows Forms Porgramming in C# by Chris Sells. I cannot say too many good things about this book, it explains the issues at exactly the level I need - and I guess due to Chris's experience, there's a lot of little tricks and techniques in there that none of the other WinForms books I have even begin to cover. Anyway, very much recommended!
