Custom Roslyn code fix providers not suggested as quick fix actions

[achobanov]

Type: Bug

Issue Description

They work as expected in VS and they were working for a few days on VS Code, but now they are no longer suggested.

Steps to Reproduce

Not sure what's changed since they stopped working. I did convert to pre-release versions of c# and c# dev kit at some point in order to test something unrelated, but I restored to stable versions afterwards. I've made no changes do my fix providers since it was working (and it's currently working in VS as mentioned)

Expected Behavior

Code fix actions should be provided in the quick fix menu

Actual Behavior

They aren't

Sorry to pepper you with issues, hope my logs help. If you need further information I'm happy to help.

Same issue, MacOS Sequoia 15.1, dot net 8.0.104.

[dibarbet]

@achobanov @dennitorf would either of you mind trying 2.56.31 (prerelease)? There is a related fix in that version that might also fix code actions.

[achobanov]

I'll check it out at the weekend.

[jsgraham]

I think I'm having the same issue. I installed the StyleCop analyzers, and while I could see the red squiggles for violations, there were no fixes suggested. Updating to the pre-release C# extension (2.57.28) brought the quick fixes back.

[dennitorf]

I have tried the pre-release version, and the issue is not fixed. I'll retry, and keep an eye on the behaviour. Thanks.

Are you able to share the code fix providers that you're using (e.g. is it a public nuget)?

[achobanov]

You can see mine here. I think this one was among those that didn't execute last time. I can double in a few days time.

Thanks - I checked it out and confirmed the action was missing in 2.55 (release), but is present in 2.57.28 (current prerelease).

@dibarbet It's working for me now, however I'd like to get a bit more time with it as the fixes were previously suggested to me and then suddenly vanished. What was the cause of the issue fixed in the prerelease?

I'm currently on v2.57.28 (pre-release)

The analyzer references containing code actions were not being included at all due to a bug when loading them on .NET core (as compared to framework in VS).

Additionally, in VSCode version 1.95.0 there was a bug where the lightbulb would not show code actions if the provider took longer than 1.5 seconds. That has since been fixed in higher versions (1.95.3 being the latest)
