WSL 2.9.3 preview

We're excited to announce that WSL Containers (WSLC) is now available in public preview. WSLC brings native Linux container support to WSL, letting you build, run, and manage containers directly through the new wslc command line tool and a fully projected SDK (C++, C#/WinRT).

Highlights of what's available in this preview:

Container lifecycle: create, run, start, kill, export, prune, and inspect containers, with per-container resource limits (--cpus, --memory, --ulimit), --shm-size, and configurable stop signals.
Images: build (with --label support), pull, push, import, save (including multiple images in a single tar), inspect, list/prune with filters, and multi-image delete.
Networking: create and manage networks, attach containers to multiple networks, network aliases, container:<name|id> network mode, custom network types, port publishing, and network prune.
Volumes: create, list, prune, and remove volumes, with VHD-backed volumes and Uid/Gid/Fixed driver options.
GPU support: GPU-enabled containers with CDI, mounted GPU executables and libraries accessible to non-root users.
Sessions: named sessions with a default session created on demand, configurable storage location, and a default of 32 GB session storage.
SDK: a C++ and C#/WinRT projection of the WSLC API, shipped as NuGet packages, plus a documented plugin API.
Tooling: wslc logs with --timestamps, --since, --until, and -n; container stats; structured CLI output with color; MSBuild and CMake build integration; and group policy (ADMX) support for management.
