What is WSL 2?

WSL 2 is a new version of the Windows Subsystem for Linux architecture that powers the Windows Subsystem for Linux to run ELF64 Linux binaries on Windows. Its primary goals are to increase file system performance, as well as adding full system call compatibility.

The primary reasons to update from WSL 1 to WSL 2 are to:

• increase file system performance
• support full Linux system call compatibility
  • 100% Linux system call compatibility
• WSL 2 uses the latest and greatest in virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). However, WSL 2 is not a traditional VM experience.
• WSL2 is 3 to 6x FASTER than WSL1

Learn all about WSL2, the new version of the Windows Subsystem for Linux, and what changes have been made to improve performance.

Craig Loewen will show you how to get things installed and set up a Linux development workflow that is integrated with Windows and VS Code. Check out the faster IO performance and Linux system call compatibility, then watch Craig run an app from inside a container using Docker Desktop for Windows and debug it using VS Code.

This new architecture changes how these Linux binaries interact with Windows and your computer's hardware, but still provides the same user experience as in WSL 1 (the current widely available version).

Individual Linux distributions can be run with either the WSL 1 or WSL 2 architecture. Each distribution can be upgraded or downgraded at any time and you can run WSL 1 and WSL 2 distributions side by side. WSL 2 uses an entirely new architecture that benefits from running a real Linux kernel.
