Скоро уже будет лет 10 как я увяз в Unity и C#… Начинал наверно как и многие с MonoDevelop 🥴 Потом появился Sublime Text, которым я пользовался пару лет, классный и быстрый редактор, у меня даже была такая же заметка про его настройку. Но он был поменян на VS Code, который тогда начал активно развиваться и поддерживаться. Собственно, до сих пор им и продолжаю пользоваться.

Далее, почему я считаю VS Code хорошим выбором для разработки на Unity и C#, также список плагинов и настроек которые использую и рекомендую.

Почему VS Code, плюсы

• лёгкий и быстрый
• бесплатный и кроссплатформенный
• гибкая кастомизация
• отлично подходит для многопроектной работы
• хорошо дружит с Git

Он действительно быстрый. Если сразу начали с него и не с чем сравнить особо, то можно попробовать отрыть средний проект в Studio или Rider и убедиться, что это действительно так. Ну и огромное количество расширений на каждый чих. И полезных и не очень.

Минусы

• более слабая интеграция с Unity
• слабый рефакторинг по сравнению с Rider
• слабее отладка
• нет встроенной навигации по Unity API

Тут минусы только в контексте работы с Unity. Некоторые из них выходят как ни странно из «плюсов», например, слабая интеграция с Unity и хуже рефакторинг — это «плата» за быстроту, бесплатность и возможность в одном редакторе работать и с C#, и c TypeScript, Node.js и с прочими языками и фреймворками. Редактор не заточен под один язык или платформу, как Xcode например.

Расширения

• C# Dev Kit — ну это база, как говорится, официальное расширение от Microsoft, лучше OmniSharp: нормальный intellisense, поддержка C# 8–12, встроенный Roslyn анализатор, быстрая индексация
• Unity Tools — подсветка методов монобехов, ссылки на Unity доки, лучше навигация по Unity API
• Error Lens — отображение ошибок и варнингов прямо в строках (спёрто у Rider 😬)
• GitLens — навигация по истории, blame, ревью и прочие git радости
• EditorConfig for VS Code — настройка форматирования через стандартизированный формат
• Todo Tree — быстрый поиск и отображение TODO-шек
• Unity — официальное расширение Unity для VS Code: API, debugger, подсказки, навигация
• Monokai Pro — тема оформления
• eppz! — ещё тема оформления

Ниже мой файл конфигурации .editorconfig который вместе с расширением EditorConfig for VS Code показывает ошибки, варнинги в именовании полей, переменных и методов, а также форматирует код в соответствии с указанными правилами.

Шрифт FiraCode

Использую данный шрифт уже давно. Это хороший бесплатный моноширинный шрифт с лигатурами (которые почему-то не всем не нравятся 🤷‍♂️). Для отображения лигатур надо включить их в настройках VS Code:

{
  "editor.fontFamily": "Fira Code", // или FiraCode-Retina
  "editor.fontLigatures": true
}

Inlay Hints

Inlay Hints — это подсказки прямо в коде, которые редактор показывает внутри строки, но которые не являются частью кода. Некоторые не включают их из-за «визуального шума», но я к ним давно привык и всегда использую.

{
  "editor.inlayHints.fontFamily": "FiraCode",
  "csharp.inlayHints.enableInlayHintsForImplicitObjectCreation": true,
  "csharp.inlayHints.enableInlayHintsForImplicitVariableTypes": true,
  "csharp.inlayHints.enableInlayHintsForLambdaParameterTypes": true,

}

Плагин для Unity

Для завершения интеграции с Unity редактором необходимо установить пакет Visual Studio Editor. Обычно он сразу включён после установки редактора, вместе с плагином для Rider.

Вот такая сборка. Не забываем обновлять расширения. Ждём CoreCLR 😅
