Font and Color configuration => become symbol ?
To make multi-character operators like =>

To make multi-character operators like => (the C# lambda operator) appear as a single symbol in your code editor, you need to enable Font Ligatures.
1. Choose a Compatible Font
Standard fonts like Courier New or Consolas do not support ligatures. You must use a "coding font" that specifically includes them. Popular choices include:
- Cascadia Code: Developed by Microsoft specifically for Visual Studio and Windows Terminal
- Fira Code: One of the most popular open-source fonts with ligatures
- JetBrains Mono: The default font for JetBrains IDEs
2. Enable Ligatures in Visual Studio
- Go to Tools > Options
- Navigate to Environment > Fonts and Colors
- In the Font dropdown, select a compatible font (e.g., Cascadia Code)
- Ligatures for symbols like =>, ==, !=, and >= should automatically render as single characters.
3. Enable Ligatures in VS Code
- Open Settings (Ctrl + ,)
- Search for Font Ligatures
- Click "Edit in settings.json" and ensure the following line is set:
editor.fontLigatures: true - Ensure your "editor.fontFamily" is set to a ligature-supporting font (e.g., 'Fira Code', 'Cascadia Code').
