Managing .NET Core Security Updates for ProfileUnity FlexApp - Console and Client Side

Overview:

This article explains how customers can independently update .NET Core components to address security vulnerabilities (CVEs) without waiting for a full Liquidware product release. ProfileUnity FlexApp uses external .NET frameworks, allowing customers to apply certain updates directly while maintaining product compatibility.

 

Important Considerations

  • Testing: Always test .NET Core updates in a non-production environment first.
  • Rollback Plan: Have a rollback plan in case unexpected issues arise (ie. vSphere snapshots)
  • Support Boundaries: This approach is supported only for security updates within the same major version family.
  • Major Version Upgrades: Do not attempt to upgrade to a new major version of .NET Core independently; wait for Liquidware to release a compatible version of ProfileUnity FlexApp.

Liquidware follows these principles for .NET Core support:

  • LTS Versions Only: ProfileUnity FlexApp only supports Long-Term Support (LTS) versions of .NET Core to provide customers with the maximum support timeline.
  • Same Major Version Family: Customers can safely update to any version within the same major version family (e.g., from .NET Core 8.0 to 8.1, 8.2, etc.) without waiting for a Liquidware product update.
  • Major Version Upgrades: Upgrading to a new major version (e.g., from .NET Core 8.x to .NET Core 9.x) requires a Liquidware product update and cannot be performed independently.

Determining Your Current .NET Version

To identify which version of .NET your ProfileUnity FlexApp installation is using, refer to our End-of-Life documentation :End Of Life For Versions of ProfileUnity & Control Panel>Programs and Features.

How to Update .NET Core for Security Patches

Server Components

  1. Check Compatibility: Verify that the update you're planning to install is within the same major version family as your current .NET Core version.
  2. Download the Update: Visit the Microsoft .NET Downloads page to obtain the latest security update for your .NET Core major version.
  3. Schedule Maintenance: Plan for a brief maintenance window to apply the update.
  4. Apply the Update:
    • Stop all ProfileUnity services
    • Install the .NET Core update
    • Restart all ProfileUnity services
    • Verify the application functions correctly
  5. Document the Change: Keep a record of the update applied for future reference.

Post Testing New version

  1. Open Control Panel>Programs and Features
  2. Note current installed versions.
  3. Simialr to highlighted, select the older versions
  4. Uninstall and reboot
  5. Test Console.

 

Client Components

  1. Update Test Systems First: Apply the .NET Core update to a small group of test systems before deploying widely.
  2. Deploy via Standard Methods: Use your organization's standard software deployment tools (SCCM, Intune, etc.) to push the .NET Core update to client systems.
  3. Verify Functionality: Confirm that the FlexApp client continues to operate correctly after the update

Post Testing New version

  1. Open Control Panel>Programs and Features
  2. Note current installed versions.
  3. Uninstall the older versions leaving newer versions (8.x in this case). Reboot
  4. Test and validate
