What's new in Windows Subsystem for Linux | DEM346
Craig Loewen presents what’s new in Windows Subsystem for Linux (WSL), focusing on end-to-end improvements and a new container workflow that enables running local Linux containers built into WSL, plus a new Container CLI and APIs for application scenarios.
Overview
This Microsoft Build 2026 session covers updates to WSL aimed at making local Linux container workflows simpler and more “built-in”, including a new container CLI and APIs intended for application use.
Key takeaways highlighted in the session
- Local Linux containers are a first-class workflow.
- Container support is built into WSL (reducing the need for extra installs).
- The approach is positioned as enterprise-ready.
WSL containers workflow and demo
- The session describes a WSL update that provides a full WSL containers experience without additional installations.
- A simple container workflow is demonstrated end-to-end.
Architecture: transparent VM + API-based container management
- The presenters describe a “transparent VM” model where containers run with a Windows host and VM components.
- Container management is exposed via APIs (and a CLI) for application scenarios.
Storage model: separation per application
- The session calls out storage separation using a VHD per application.
Preview and resources
- The session closes with a public preview announcement and an invitation to provide feedback.
