I was running into an issue with smc_linux and was having trouble getting past the following error:
WARNING: The runtime version supported by this application is unavailable.
Using default runtime: v4.0.30319
Unhandled Exception:
System.IO.FileNotFoundException: Could not load file or assembly or one of its dependencies.
File name: 'System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
Searching the forums here was leaving me empty handed and ducking it ran me down the trail of .net framework issues. I finally found an similar issue listed here in the forums with someone not being able to run a different GUI in Ubuntu. There fix also fixed my issue.
sudo apt-get install libmono-system-windows-forms4.0-cil
I would suggest adding that to the README file so that others don’t fall into the same trap.
