    Close #24508: Backport the 3.5 MSBuild project files.

    The old project files move to PC/VS9.0 and remain supported.

    VS2008 is still required to build 2.7; VS2010 (or later, plus Windows SDK 7.1)
    is *also* required to use the new project files.

Between builds 367 and 368, the number of warnings doubled: 404 warnings => 796 warnings.

Recent build:
