I've been using a Package from ceztko on GitHub called SolutionConfigurationName.
I rebuilt it to add compatibility with VS 2012, and it has been working well for some time. However, I just installed VS 2013, and it is no longer functional for C++ projects (vcxproj), though it does work for C# projects.
It uses ProjectCollection.GlobalProjectCollection.SetGlobalProperty to set variables for SoluctionConfigurationName and SolutionPlatformName, which are kept in sync with properties of SolutionBuild.ActiveConfiguration.
My use of the resulting "macros" is in the Output Directory of my projects:
$(SolutionDir)\Builds\$(SolutionName)_$(SolutionPlatformName)_$(SolutionConfigurationName)\
This has been a very valuable solution to consistent solution-based build output, and I hope there's a work-around or some update I can make to this package to get it working again. I'd appreciate any insight anyone has.
Thanks!
