CA0067
Directory not found.
The value of the /directory option in the FxCopCmd command line was not found.
This warning can occur if you are using the CodeAnalysisDependentAssemblyPaths property of MSBuild to specify additional reference assembly search paths and one of those paths does not exist.
If warning CA0067 appears with CA0058 errors or CA0060 warnings, resolving the other errors usually resolves CA0067.
If warning CA0067 appears without other errors or warnings, you can usually ignore the warning because the directory was not needed.
