How to completely remove Visual Studio from mac?

I recently installed Visual Studio for mac right after the day it was launched. It consumed 20 gb of my disc space, so I decided to remove it. I went in to the applications folder and moved recently installed components associated with the installation to the trash. But it did not free any space at all. So I searched online and followed the following link for uninstallation: Uninstalling Xamarin

After following the link and entering all the terminal commands, I was only able to free up 10 gb of storage. How do I free up the rest 10 gb of the storage ?

Uninstall Visual Studio for Mac App

Step 1. Locate Visual Studio.app in the /Applications directory and drag it to the Trash Can. Alternatively, right-click and select Move to Trash.

Step 2. Remove all traces of Visual Studio for Mac

Execute the following commands in your terminal:

sudo rm -rf "/Applications/Visual Studio.app"
rm -rf ~/Library/Caches/VisualStudio
rm -rf ~/Library/Preferences/VisualStudio
rm -rf "~/Library/Preferences/Visual Studio"
rm -rf ~/Library/Logs/VisualStudio
rm -rf ~/Library/VisualLodStudio

Uninstall Xamarin.Android

sudo rm -rf /Developer/MonoDroid
rm -rf ~/Library/MonoAndroid
sudo pkgutil --forget com.xamarin.android.pkg
sudo rm -rf /Library/Frameworks/Xamarin.Android.framework 

Uninstall Xamarin.iOS

rm -rf ~/Library/MonoTouch
sudo rm -rf /Library/Frameworks/Xamarin.iOS.framework
sudo rm -rf /Developer/MonoTouch
sudo pkgutil --forget com.xamarin.monotouch.pkg
sudo pkgutil --forget com.xamarin.xamarin-ios-build-host.pkg

Uninstall Xamarin.Mac

sudo rm -rf /Library/Frameworks/Xamarin.Mac.framework
rm -rf ~/Library/Xamarin.Mac

Uninstall Workbooks and Inspector

sudo /Library/Frameworks/Xamarin.Interactive.framework/Versions/Current/uninstall

Uninstall the Visual Studio Installer

rm -rf ~/Library/Caches/XamarinInstaller/
rm -rf ~/Library/Caches/VisualStudioInstaller/
rm -rf ~/Library/Logs/XamarinInstaller/
rm -rf ~/Library/Logs/VisualStudioInstaller/
rm -rf ~/Library/Preferences/Xamarin/
rm -rf "~/Library/Preferences/Visual Studio/"

Uninstall Mono SDK (MDK)

Warning

There are other applications outside of Xamarin which also use Mono, such as Unity. Be sure that there are no other dependencies on Mono before uninstalling it.

sudo rm -rf /Library/Frameworks/Mono.framework
sudo pkgutil --forget com.xamarin.mono-MDK.pkg

Other apps with name prefix Xamarin

The official guide didn't mention it, but I found there were other apps named Xamarin.xxxx in my library directory. I simply moved them to trash.

May be this would be better solution (no need to follow each step): https://raw.githubusercontent.com/MicrosoftDocs/visualstudio-docs/master/mac/resources/uninstall-vsmac.sh :

If you haven't dealt with bash script before, you may look at its documentation too: https://docs.microsoft.com/en-us/visualstudio/mac/uninstall

Actually, it is pretty easy. Create a file with extension .sh (for example, vsremover.sh) and paste the code above. Save. Open terminal application, go to the place where you saved the file (for example: cd /Users/yourname/Desktop) and type the following:

chmod +x vsremover.sh

Then run it:

./vsremover.sh
