  1. Compile and install your own Mono version into a specific prefix. For the purpose of this guide, we are going to use /home/marek/mono. For an even better debugging experience you could configure your Mono with the --disable-bcl-opt option.

  2. Launch Visual Studio for Mac

  3. Go to Visual Studio -> Preferences and add your prefix path where you installed your locally built Mono.
