Microsoft Message
We have scheduled your Business Central environments running version 28.x for planned maintenance to introduce support for .NET 10. This update is required, and the maintenance will occur outside of your environments’ regularly scheduled updates, as .NET 8 reaches its official end of support in November 2026.
How does this affect me?
During this maintenance, users will be unable to access your environment.
This update will begin during your environment’s configured update window, prior to November 10, 2026. Unlike typical application updates, this cannot be scheduled for a specific date or time by an administrator. However, you can cancel a running update from the Admin Center.
What action do I need to take?
Please review the update window configured for your environment and ensure it is an appropriate maintenance period for your operations. Communicate as appropriate with your users
