I can’t find settings for C# in vscode for set a different colors for interfaces/usings and [local variables/class properties] like in Visual Studio.
>Solution :
In Visual Studio Code, open the Color Theme picker with File > Preferences > Theme > Color Theme. OR use the keyboard shortcut Ctrl+K Ctrl+T to display the picker. Use the cursor keys to preview the colors of the theme. Select the theme you want and press Enter.
To tune the editor’s syntax highlighting colors, use editor.tokenColorCustomizations in your user settings settings.json file: ref:https://code.visualstudio.com/docs/getstarted/themes#_editor-syntax-highlighting
I borrowed that from ref: https://code.visualstudio.com/docs/getstarted/themes#:~:text=In%20VS%20Code%2C%20open%20the,you%20want%20and%20press%20Enter.
