Issue
The recent addition of a hidden WinForm pulled in a number of binaries that in total were over 30 MB. This is overkill for what we needed.
Change
Replace that hidden WinForm with a native window proc handler.
Validation
Manual testing of triggering the event using the environment variable panel in Windows.
Ensured that the window proc and process exit cleanly when configuration server is shutting down.
