Hmm, actually, the v9 package is targeting both .NET 8 and .NET 9 (and others, like .NET Standard 2.0). So, there shouldn't be a reason to keep 8.x for .NET 8, right @sebastienros? The different version I added under #17190 is not actually useful.

[Piedone]

Ah no, it is necessary, because of System.Text.Json, see the build error. Rejecting this, then.

Renovate Ignore Notification

Because you closed this PR without merging, Renovate will ignore this update. You will not get PRs for any future 9.x releases. But if you manually upgrade to 9.x then Renovate will re-enable minor and patch updates automatically.

If you accidentally closed this PR, or if you changed your mind: rename this PR to get a fresh replacement PR.

[sebastienros]

Because the 9.0.0 version's net8.0 dependencies are pointing to net9.0 Ms packages, we need to keep pointing to 8.0.x version for the net8.0 TFM in OC.

Yep, thanks.
