Which rule from FxCop do you deactivate?

Question

I personally don't use FxCop yet. We want to work out the unit testing first before going with code analysis. However, which rules would you permanantly deactivate? Which rules would you deactivate temporarily and in which situation?

Answer 1

I dislike rule CA1021: Avoid out parameters. Out parameters are useful for many different patterns (including the .Net Try* pattern). Out can certainly be overused but really it seems overkill to have an FxCop rule for it.
