I'm guessing they work just fine on your machine too, but that the problem is you can't run them because you don't know where they are.devenv "D:\inventory\inventory.sln" /build Debug
its not working, even msbuild.
C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe
