Is this a bug or expected issue?

Action itself is dead simple:https://github.com/Gigas002/dotnet_gh_deploy/blob/master/.github/workflows/codeql.yml
But looking at logs,codeql tries to usedotnet 8.0 instead, which fails:https://github.com/Gigas002/dotnet_gh_deploy/actions/runs/13724205415/job/38386637583

Hi@Gigas002,

The default version ofdotnet onubuntu-latest is currently8.0.112, so that is what CodeQL uses. If you are targeting a9.x project, then you will need to install that version ofusing asetup-dotnet step in your workflow before initialising CodeQL.
