Microsoft released Development Guide for CCF 2008 and this is very good document to read if you want to get started with CCF 2008.

I recommend reading it... the only weak section that I saw in this document, was error logging section. They briefly mentioned that errors can be logged into Database but there are no useful code samples provided and only a small paragraph of text covering DB logging.
