VS Code is the full name Visual Studio Code, which is a free and open source cross-platform code editor and development environment developed by Microsoft. It supports a wide range of programming languages and provides syntax highlighting, code automatic completion, code snippets and smart prompts to improve development efficiency. Through a rich extension ecosystem, users can add extensions to specific needs and languages, such as debuggers, code formatting tools, and Git integrations. VS Code also includes an intuitive debugger that helps quickly find and resolve bugs in your code.

The reasons for the installation of VS Code extensions may be: network instability, insufficient permissions, system compatibility issues, VS Code version is too old, antivirus software or firewall interference. By checking network connections, permissions, log files, updating VS Code, disabling security software, and restarting VS Code or computers, you can gradually troubleshoot and resolve issues.

How to back up VS Code configurations and extensions? Manually backup the settings file: Copy the key JSON files (settings.json, keybindings.json, extensions.json) to a safe location. Take advantage of VS Code synchronization: enable synchronization with your GitHub account to automatically back up all relevant settings and extensions. Use third-party tools: Back up configurations with reliable tools and provide richer features such as version control and incremental backups.
