It appears as though the ReSharper SDK’s ILineCommentActionProvider usage is broken from 2025.3.1 and onwards. It was previously a non-issue for 2025.3.0.*
I noticed this on the Reqnroll.Rider plugin here: CTR+/ stopped working in .feature file · Issue #75 · reqnroll/Reqnroll.Rider · GitHub, however I’m not sure it’s the fault of the plugin. I’m able to run the 2025.3.0 version locally and the comment action works without an issue, however when I upgrade it to 2025.3.1 (literally the only change is the version number, no code changes), then the comment functionality stops working and I get a warning in the logs when I debug it
WARN - #c.j.r.a.b.FrontendActionUpdateInterceptor - Non-cached operation BackendDelegatingAction#update@keyboard shortcut (com.jetbrains.rdclient.actions.base.BackendDelegatingAction(id=CommentByLineComment)) "CommentByLineComment", backendActionId=RiderLineComment, response=null
Is this a known issue?
