Back from my holidays! i hope you will have a very good 2003!
During my holidays i read Beginning Visual C#: one of the best books i ever seen!
Karli Watson & C. are clear in explaining tecniques and tutorials and the book is never complex. Require VisualStudio.NET or VisualC#.net Standard Edition installed.
Through classes and function you learn how to write even more complex application by using console or Windows Form.
If you need to learn C#, this could be a pretty good point of start.
Bookmarks at-a-glance: http://www.icsharpcode.net/OpenSource/SharpZipLib/
C# Zip/tar/gzip/Bzip2 library for projects that need a compression routine. You can use both for you web-based asp.net sites or Windows Form runtimes.
Seeya!
