Hello @Valentin THOMAS ,
Welcome to Microsoft Q&A forum.
Spell Checker is a new feature in Visual Studio 2022(from 17.5 preview 3). Since C#, C++ and Markdown all use English as the language for their keywords, Visual Studio will always use the "English (United States)" or "en-us" dictionary for spell checking. Visual Studio will also ask the instance of Windows for the display language it’s using, and if it’s not "en-us", it will use that dictionary as well. It is by-design currently.
Spell Checker uses editorconfig for configuration, if you want to re-add English, you need to use a
.EditorConfig file and set following:
Besides, if it worked before then resetting VS(run
devenv /ResetSettings in
Developer Command Prompt for Visual Studio 2022 ) may also work, see this document: /ResetSettings.
