Visual Studio Code is a lightweight, portable, open source IDE from Microsoft, written mostly in TypeScript and built on top of the Electron shell. VS Code provides comprehensive editing and debugging support, an extensibility model, Git support, and lightweight integration with existing tools. There is a good selection of extensions to VS Code available from Microsoft and the community.
VS Code 1.3 introduced Visual Studio-like tabs in the editor, as well as Visual Studio-like global search and replace and diff-ing. Version 1.3 also introduced a new paradigm for stacks of open editors and the concept of a preview editor. Single-clicking a file in the Explorer brings the file up in a nonsticky editor that will be replaced by the next preview. Editing the file makes it sticky. VS Code retains its Visual Studio-like peeked editors.
VS Code runs on OS X, Linux (both Debian and Red Hat distros), and Windows. VS Code on Windows requires .Net Framework 4.5.
