Use the tool, tool part 7

Right I have one more .NET tool to recommend and then I'm done. And that is FxCop. This will analyse your assemblies and tell you all the problems it finds. And my word, does it find a lot of things. The fact is a lot of the rules are just plain anal, but it still finds stuff that could be a problem. And whats more, you can add your own rules, although I can't say I've ever done this.
