TestAssemblyDirectoryResolveAttribute
Marks a test assembly as needing a special assembly resolution hook that will
            explicitly search the test assembly's directory for dependent assemblies.
            This works around a conflict between mixed-mode assembly initialization and
            tests running in their own AppDomain in some cases.
