• anyOS: @sandy081 - tested on Windows
• anyOS: @isidorn - tested on OS X

Complexity: 2

Steps

• install a Language pack from the market place (e.g Bulgarian)
• close VS Code.
• restart VS Code with --locale=the language pack you downloaded (e.g --locale=bg)
• go to the user data directory on your file system. Under Windows that is C:\Users\${user}\AppData\Roaming\Code - Insiders
• ensure that there is a languagepacks.json file and a directorry clp
• navigate into clpand ensure that there is a directory with a hash and the locale of the language pack you installed
• close VS Code
• restart again with the locale switch
• open the log for the shared process. After ~40 seconds you should see a message that the language pack cleanup starts and that the installed language pack is skipped since it is still in use.
• uninstall the language pack
• close VS Code and restart it without a locale switch
• open the log for the shared process. Again after ~40 seconds you should see a message that the language pack cleanup starts . This time a language pack cache entry should be deleted.
• go to the file system again. Ensure that the directory entry below clp got deleted.
