I reported earlier that .NET Framework 4.7.2 is not supported on any Exchange Servers and many users, including myself, were seeing high CPU usage on AAD Connect servers.
Doesn't anyone test this stuff, or is that our job as customers? What's the point of pushing out an update as "important" that core functionality doesn't support and actually harms the infrastructure that enterprises rely on? It takes a server restart to install this update and another one to remove it. And every time we get a .NET Framework update and reboot, server performance is affected while all the .NET Framework assemblies are recompiled. NO MORE.
From now on, I don't plan to install any .NET Framework updates unless,
- It's required for server functionality.
- It fixes a security vulnerability that actually affects me.
- It's been deployed worldwide for at least two weeks.
Not everyone is a developer who has to have the latest API updates.
Microsoft, stop pushing buggy updates as "important". It's embarrassing. Get your quality issues sorted out, test, and coordinate with other product teams.
