My projects are still targeting net8 I did nothing other than do a build which did a restore and the world is broken.

However what is this upgrade guide you mention?

Anyone else having issues with @visualstudio.bsky.social and Dotnet #MAUI after the Net9 release? Both my laptop and desktop machines can no long run existing projects that were Net8 and I can't even get a dotnet new MAUI project to build. Looking for solutions before I throw computers out.
