Hi Hidayath,
Thank you for reaching out!
From your screenshot, it looks like the dropdowns for Package source and Default project are disabled. This typically indicates that the NuGet Package Manager extension isn’t fully loaded or there’s a disruption in the environment setup. Since it works fine in Visual Studio 2022 but not in Visual Studio 2026 Insider, it’s likely related to configuration, or the preview build itself.
We’d really appreciate it if you could submit a report via Help → Send Feedback → Report a Problem. This will help our team gather diagnostic data and improve the experience in future updates.
In the meantime, here are a few troubleshooting steps you can try:
- Check if NuGet Package Manager extension is enabled. You can go to Extensions → Manage Extensions. Search for NuGet Package Manager and check its status.
- Clear Visual Studio Cache Delete the following folders and restart Visual Studio:
%LOCALAPPDATA%\Microsoft\VisualStudio\<version>\ComponentModelCache
%LOCALAPPDATA%\Microsoft\VisualStudio\<version>\MEFCache
- Check the ActivityLog for errors Look for any NuGet or PackageManagerConsole related messages in:
%APPDATA%\Microsoft\VisualStudio\<version>\ActivityLog.xml
- Repair Visual Studio Open Visual Studio Installer → More → Repair.
- Reinstall the NuGet Package Manager extension You can uninstall and reinstall it directly from the Extensions menu.
I hope this helps you fix the problem quickly! If you agree with our suggestion, feel free to interact with the system accordingly!
