Problem building VS 2013 solution after upgrading to v9.2

[MOConnor]

Thanks for replying but I don't think that's the issue. This is a solution we build every night without any problems. The only thing that changed was upgrading Visual Build from version 8.7 to 9.2.

v9 is more precise about matching the declared version in the solution/project with the devenv/msbuild version (it could have matched a compatible version by luck in the past when the declared version wasn't actually correct), and that's the only relevant change to the Make VS* actions.
