Ncrunch and PostSharp

I have an F# project that uses PostSharp. PostSharp build task tries to load nCrunch.TestRuntime!!!!
It is the latest 2.7 ncrunch version.

NCrunch: If you are experiencing problems in getting this project to build, have a look at http://www.ncrunch.net/documentation/troubleshooting_project-build-issues

WARNING - Library1.fs (7): The type 'FsBaseEntity' implements 'System.IComparable' explicitly but provides no corresponding override for 'Object.Equals'. An implementation of 'Object.Equals' has been automatically provided, implemented via 'System.IComparable'. Consider implementing the override 'Object.Equals' explicitly


Any ideas how to configure the build properly?

nCrunch.TestRuntime.dll should normally be loaded into the GAC during the NCrunch installer.

If it isn't there, installing it manually using GacUtil should solve this problem. It's a DLL that is used fairly widely through NCrunch processing, so keeping it in the GAC is the best place.
