WSL container is a new feature coming to the Windows Subsystem for Linux (WSL), announced at Microsoft Build 2026. It provides a built-in way to run OCI-compatible Linux containers on Windows without third-party tools like Docker Desktop. The feature includes two parts: a command-line tool, wslc.exe, and a developer API. As of June 2026, it is in active development and has not shipped as part of a stable WSL release.
