The TypeScript 7 Beta — the full Go-port, not a JS shim — is now the default language service in the latest Visual Studio 2026 Insiders build. That's a meaningful integration step: it moves the fast native compiler out of CLI experiments and into an IDE most enterprise Windows teams already run. Switching it on by default in an Insiders build is how Microsoft stress-tests compatibility before a broader rollout. If your team uses Visual Studio rather than VS Code, this is the moment to opt in and surface any issues with your specific project configuration before the stable channel picks it up.
