Organise Usings on Save
If your linter is complaining about unused usings or import sort order, you can make it stop by organising your usings using the shift+alt+o shortcut in VSCode.
But to save some typing, you can just get VSCode to do this for you on every save by adding the following to your settings.json:
"editor.codeActionsOnSave": {
"source.organizeImports": true
}
