@mdarocha @corngood tagging you guys as you seem to be interested in .NET on NixOS

Also a very similar PR for another less popular .NET tool (DBus binding generator): #360047

The only problem I see here is that the commit messages are non-standard. The new package should be [package name]: init at [version], and the maintainer commit should probably be prefixed with the module name. Take a look at the history of that file for guidance.

Same goes for the other PR you mentioned, but we might as well finish one of them and rebase the other to remove the maintainer commit.

Thanks! I see there's a 9.0.0 version on nuget.org. Are these tied to runtime / SDK versions? I'm just trying to understand if we'd need both 8+9, and if not, when we would want to move to 9.

@corngood I tried to upgrade and even though my system does not have .NET 9 the 9.0.0 worked, so I bumped the version.

My original reasoning was to stay on the LTS side just in case.

Looks good, thanks.
