I no longer remember how this stuff works, but can we stick to dotnet 8 SDK and versions? Or do you really need 9?

Due to the new nullness-related constructs, compiling the current compiler service requires 9.0 or higher for both fsc and FSharp.Core.
That's why I wrote above that this PR might be a draft one for quite some time.
I am assuming you might want to wait for the LTS SDK 10.
Regarding features I don't think there is a big pressure to move. The current Fantomas can deal with sources that contain nullness constructs or #warnon.
It is just that the changes accumulate. I naively just wanted to make the changes for "scoped nowarn" but found I had to deal with three other breaking changes also.

Do you have any more details on that? What exactly in FSharp.Core 9 does any of this depend on?
Uh oh!

It is all about nullness.
If I compile with SDK 9.0.300 and FSharp.Core 8.0.100, I get 85 errors in the Fantomas.FCS project, mostly about unknown
objnullandNonNull.
