Build fails for my application when building for the AppStore target with the following error:
MMP : error MM2002: Failed to resolve "System.Diagnostics.PerformanceCounter" reference from "System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
Obviously it's a linking problem, I'm wondering if something has changed in a recent update because this has been working fine up until this build and I haven't knowingly made any changes involving System.Diagnostics.
I've attached verbose build output and version info of my environment in the hope that someone can help.
