So you are serious about your code quality huh... well StyleCop is a fantastic tool to ensure that. The best part is, it integrates with Studio 2008. It is simple.
Now when you use StyleCop, most of the warnings are not what you really want to work upon. Like Documentation, for instance, who cares whether there is a blank space line above a comment or not...? So you can go to Solutions Explorer and click on Style Cop Settings. This will bring up the "Microsoft StyleCop Project Settings" Dialogue box which will allow you to customize your rules set. Allow you to enable / disable rules as per your own special requirements / whims / fancies / moods... :)
It is a fun little tool and I could have written more about it but then I decided that I won't spoil the fun. You guys go ahead and explore.
