MSBUILDEMITSOLUTION not working with .NET 4?
Set MSBuildEmitSolution=1 and then build from the command line. You should then see a MySolution.sln.metaproj file near MySolution.sln. Notes: If you open a command prompt window, then set the env var via System Settings, you will have to open a new command prompt. You’d think you could also use msbuild /p:MSBuildEmitSolution=1, but you can’t.
