@Numpsy I saw you mentioned that Fargo was AOT compatible. Did you run into this issue when testing this?

[Numpsy]

I have a CLI tool in a project at work that's working with Fargo in AOT.

Do you have any AOT analysis warnings in the build that suggest issues?

[Numpsy]

Actually, looks like it might be dotnet/fsharp#15488 (reported by the author of Fargo)?

[TobyShaw]

That was it, bingo!
Thanks very much for tracking that down!

[TobyShaw]

@nojaf Do you know why the builds aren't completing? I'd like to get to all green ticks before swapping the PR to be non-draft.

[nojaf]

I need to press a button to approve running CI first. I believe this is because it is your first contribution.

[nojaf]

You might also want to sync your PR with the latest main.

[TobyShaw]

Thanks!

If the lock file is too much of a pain, I think I can live without them.

[TobyShaw]

I think I've solved the lockfile issue, I was mostly just getting confused as I accidentally left a stray RuntimeIdentifier in Fantomas.fsproj.

[TobyShaw]

@nojaf I see that my build is succeeding in the dev container ( https://github.com/fsprojects/fantomas/actions/runs/9841310391/job/27168319253) but not on the other platforms (https://github.com/fsprojects/fantomas/actions/runs/9841310391/job/27168319712)

Do you have an idea what's different between the dev container vs the other platforms, and how to fix this?

[baronfel]

If you use lockfiles then you'll need to pin the SDK version very strictly (no floating at all) to ensure reproducibility. The AOT support packages bump with almost every release of the SDK (including monthly security releases) and so are very up for change.

The lockfile mechanism in NuGet doesn't easily allow for ignoring these kind of sdk-provided packages, and it's an area of pain that the SDK team is trying to bridge with the NuGet team.

So right now, either:

• use global.json to pin to a single sdk version across contributors, maintainers, and CI/CD and continue to use lockfiles
• stop using lockfiles

does the dev container only have the 8.0.200 SDK installed, and the other runners have that plus 8.0.3XX ?

[TobyShaw]

If the lock file is too much of a pain, I think I can live without them.

Thinking about this more, how about they're kept for the main pipeline but we pass -p:RestoreLockedMode=false to the AOT-publish pipeline? I'd like to avoid muddying the main repo with this publish method, mostly because AOT seems not very well supported in the .NET ecosystem yet.

Would work for me.

Yes, taking a look at this in #3100

[nojaf]

@TobyShaw could you rebase (or merge master) again?

[TobyShaw]

Sorry for commit spam, having to edit via the browser lol

[nojaf]

Hi @TobyShaw, I've changed the base branch to v7.
Please target that branch going forward. We can make breaking changes there if necessary.

[nojaf]

Hello @TobyShaw, do you have any plans to pick this up in the near future?
I'm asking if we need to wait to release Fantomas v7 for this feature.
