I don't know who Mikhail is,
but his 4 year old entry on FxCop and CCnet was perfect.
The only thing I needed to do was to change the references to from FxCop 1.35 to FxCop 10.
I was prepared to use
Basharat's solution, but it turns out that ccnet version 1.6.7981.1 is already taking care of the FxCop v10 reporting issues.
