Lack of MSBuild inside the Mono6 package

[DamienCassou]

From what I understand (which is not much), the Mono 6 package is supposed to include MSBuild 16.0. Nevertheless, this doesn't seem to be the case in nixos-unstable. Is there a reason? Is there something we can do about that?

I have the same doubt, when using omnisharp, it says that can not find MSBuild from mono.

[ericdallo]

Maybe @thoughtpolice , @obadz or @vrthra, the mono maintainers could help

@DamienCassou I opened this PR that fixes it for Unity, I don't know if your problem is related, but you could try do the same I did there: #95911

[DamienCassou]

@ericdallo From what I understand (which is not much) the msbuild package is only meant to build msbuilt itself: https://github.com/mono/msbuild/releases. I tried to use that to develop .Net applications with Rider, but this didn't work.

[ericdallo]

Yes, the msbuild should only build msbuild with mono dependency, I opened a PR for omnisharp-rosly which depends on both msbuild and mono6.
Maybe your issue should be fixed if you build msbuild and mono6 on your nix

I think this was fixed here, right?

[DamienCassou]

For me things still don't work. I tried building an environment with:

nix-shell -I nixpkgs=. -p msbuild mono6 dotnet-sdk_5

and then feeding the paths to msbuild, mono and dotnet to Jetbrains Rider but the latter sends me weird error messages. I don't have any problem when installing mono with Snap in a Fedora workstation.

I'm still interested in this issue. It is the only blocker to replace Fedora with NixOS.
