Product and Test updates
- [ ] [All teams] Do a compatibility check for the product with the new OS
- [ ] [CoreCLR/CoreFX] Runtime / RID Support update
- [ ] [Infra] Ensure that the correct Docker images used by teams are built in the dotnet-buildtools-prereqs (if applicable)
- [ ] [Infra] Replace docker tags used in builds across repos and branches
- [ ] [CLI team] Update CI legs to latest updated Dockerfile
- [ ] [All teams] Update test infrastructure to support the new version
- [x] ~[Acquisition] Add support within nightly repos~
- [x] ~[Acquisition] Deploy to master (GA) during next patch release cycle~
Release team:
- [x] Notify .NET Core teams regarding new OS release
- [ ] Update the supported OS content on GitHub and marketing sites.
Document updates:
- [ ] Add OS prerequisites to the dependencies document
- [ ] Update distro install page
@rbhanda Note: Starting with .NET 8.0, the RID graph is frozen. In other words, adding RIDs is currently only needed for 6.0 and 7.0.
For reference, see issue https://github.com/dotnet/runtime/issues/90000 and PRs https://github.com/dotnet/runtime/pull/90297 (which was merged to 8.0 before it was shipped).
The 7.0 runtime PR has been closed for the reasons described in the PR: https://github.com/dotnet/runtime/pull/98079#issuecomment-1934981974
The 6.0 runtime PR has been merged.
Just a note, Fedora 40 just landed! Is 8.0 available for it now?
If you are looking for Fedora-maintained packages (ie, maintained by the Fedora .NET SIG, as opposed to Microsoft built/maintained .NET packages), .NET 6.0 and .NET 8.0 have been available in Fedora repos since 40 entered development.

Nice! Does Microsoft maintain a first-party .NET fedora package repo?
Yes, it does. https://packages.microsoft.com/config/fedora/40/ https://packages.microsoft.com/fedora/40/prod/
@rbhanda I have a question regarding the versioning.
As of today(4/26/2024), Microsoft packaged dotnet-8.0 packages on packages.microsoft.com have version number 8.0.4-1. The Fedora 40's dotnet-8.0 packages have version number 8.0.4-1.fc40, and DNF would see Fedora ones newer than Microsoft's ones, is that a desired/expected behavior?
In dotnet --info outputs, Commit ID of the "Host" section are the same, 2d7eea2529. But in the .NET SDK section, Microsoft packaged one is returning version 8.0.204, with commit ID c338c7548c, Fedora's is returning version 8.0.104 with commit ID 034f91fcc0.
@inntran I recommend against any mixing of Fedora-built and Microsoft-built packages of .NET.
You should enable the Microsoft repository, and disable fetching any dotnet packages from Fedora. Or you should disable the Microsoft repository and only use dotnet packages from Fedora. Having both enabled will pull down some packages from each repo - as you discovered - which will result in a broken .NET installation.
We have some steps on how to do that here: https://learn.microsoft.com/en-us/dotnet/core/install/linux-package-mixup?pivots=os-linux-redhat
I thought it might help to say if I install .NET 8.0 on Fedora 40 from Microsoft's repository and not the Fedora-maintained repos, I get the following message when running a dotnet command (e.g. dotnet new) :
You must install or update .NET to run this application.

@mdx0111 That issue is https://learn.microsoft.com/en-us/dotnet/core/install/linux-package-mixup?pivots=os-linux-redhat again.

@omajid I don't think so as I have excluded Fedora maintained .NET packages altogether.
@mdx0111 Hm. Can you run a sudo dnf upgrade --refresh? I think you might have picked up a newer sdk but not the newer runtime from the Microsoft packages repo.

@omajid Thanks for the help! That's all sorted now.
