If you have configured your Azure AD Connect (the directory synchronization tool for Azure AD and Office 365), a new version (1.1.880.0) has been made available.
This version solves the issue with Azure AD Connect Health agent running 100% CPU – which was (incorrectly?) reported to be related to the Framework update.
Also part of this update support for Windows Server 2019 Essentials and GA (general availability) of the integration with Ping Federate (which was in preview with the previous version).
As part of the additional updates, Azure AD Connect is now able to create a backup of your AD FS (Active Directory Federation Service) Trust (if you use AAD Connect for AD FS configuration) each time an update is made (see https://aka.ms/fedtrustinaadconnect), update to the latest version of SQL Server 2012 Native Client or ‘Seamless Single Sign-On’ is now enabled by default when selecting Password Hash Synchronization (known as Password Synchronization) or Pass-Through Authentication.
Download for ‘non auto-upgrade’ configuration should be made available soon.
