The Microsoft Learn .NET interactive editor can disappear due to backend service issues or API errors when loading certain modules (like the strings unit). It’s not browser-specific and often resolves after Microsoft fixes the service.
Steps for debugging.
- Sign Out and Back In Refresh your session completely to clear any stale authentication tokens that might prevent the editor from loading.
- Use Private Window Incognito mode bypasses cached data and cookies, which can interfere with the interactive editor’s scripts.
- Switch to Chrome Chrome is generally more stable for Microsoft Learn’s interactive editor because it handles the required JavaScript and sandboxing better than some other browsers.
- Disable Extensions Use a clean browser profile without ad-block or privacy tools. These can block API calls or scripts needed for the editor.
- Check Network VPNs or corporate firewalls may block Learn’s API calls. Ensure you have an open connection or temporarily disable VPN.
- Fallback If the editor still doesn’t load, use Visual Studio Code or Visual Studio locally for exercises. This ensures you can continue learning without waiting for the platform fix.
