When will it be updated to. NET 9

[nczsl]

After installing the new version and deleting the old version, it no longer works

[konst-sh]

I have net8 class lib project in which I included System.Text.Json 9.0.0 package, and after that I'm no longer able to reference that project dll in notebook as it always argues on assembly versions conflict

[jonsequitur]

The update (#3760) is in our November sprint plan.
