As part of my responsibilities as author, I provide ongoing support for my books through my web site. You can also obtain the source code for all of the examples in Programming C# at my site:

On this web site, you’ll also find access to a book-support discussion group and a section set aside for questions about C#. Before you post a question, however, please check to see if there is an FAQ (Frequently Asked Questions) list or an errata file. If you check these files and still have a question, then please go ahead and post to the discussion center.

The most effective way to get help is to ask a very precise question or even to create a very small program that illustrates your area of concern or confusion. You may also want to check the various newsgroups and discussion centers on the Internet. Microsoft offers a wide array of newsgroups, and Developmentor (http://www.develop.com) has a wonderful .NET email discussion list as does Charles Carroll at http://www.asplists.com.
