Creating New Rules
You can add new rules to FxCop to meet specific organizational needs. To add the rules, you need to build an FxCop add-on, using the FxCop SDK. Essentially, a rule is a form of code parser based on an FxCop interface. You'll probably find that the rules provided with FxCop will make your code far better than before, so the use of additional rules isn't necessary. A complete demonstration of new rule code is outside the scope of this article, but it's good to know that the feature exists.
