Description Karol Gwaj 2012-12-11 13:56:42 UTC
Environment.SetEnvironmentVariable not setting environment variables if EnvironmentVariableTarget is Machine or User (working fine for Process), after checking the code i found this:

case EnvironmentVariableTarget.Machine:
    if (!IsRunningOnWindows)
case EnvironmentVariableTarget.Process:
    if (!IsRunningOnWindows)

so it will actually never work on non windows OS. I think mono as cross platform framework should work this same on every operating system.

Also maybe instead of returning silently for non windows OS, it should throw NotImplementedException (or NotSupportedException) depending on the future plans for this functionality. To be honest it will save me a lot of time if i will know from first try that this method is not fully supported on unix (I spend good 1h trying some workarounds before deciding to look into the implementation)
