text: Since May 10, .NET 5.0 is EOL (End Of Life), and should not be used. Should it be marked as EOF similar to dotnet 2.2 and 3.0? See All packages using dotnet 5.0 should be updated to use a newer, supported version. These packages still need updating: [x] - [x] - [x] - [x] pkgs/development/tools/build- - [x] -
There is at least one package, which currently uses dotnet 5 sdk - . So we will need to update it beforehand. Btw, I'm not sure if we have any policy regarding packages removal, for nixpkgs in general or specifically for it's dotnet part. , what do you think?
The package is also using .NET 5: . But this is because I made the PR upstream updating it from .NET 4 to 5. I suspect that the transition to 6 will be similarly easy.
I think we should just mark it as depricated, as many projects do still use it upstream. Dotnet version 3 is also still commonly used, so I dont expect it would be realistic to remove version 5 any time soon. also uses dotnet 5 by default, I'll go ahead and switch that over now. See . That doesnt mark dotnet 5 as deprecated or change anything from a SDK perspective, just some preperation work.
See as well, it adds a warning whenever dotnet version 5 is used. Not using a throw for now since a few packages depend on it and I dont have the time to clean that all up at the moment.
Can you provide a list of packages that need updating?
Based on a quick grep: pkgs/development/tools/build-
I believe that after all the above PRs are merged, we should be able to safely remove .NET 5 from nixpkgs :)
