I've released FxCop Integrator 1.3.0p1.
In this release, I temporarily disabled the "Code Analysis on Build" feature that is implemented in ver1.3.0, because I realized that events of EnvDTE.BuildEventsClass don't raised on VS2010 SP1(*). "Code Analysis on Build" depends to their events, so I had no choice but to disable it. I'll enable this feature in the future release if I can find out a workaround.
This version is also improved performance and fixed some bugs.
* I sent a feedback about this problem to Microsoft Connect.
