Guix package

[Ambrevar]

I'm trying to package msbuild (the build tool for Mono) for Guix.

I have a Guix definition that should be ready (https://gitlab.com/nonguix/nonguix/-/blob/wip-mono/nongnu/packages/mono.scm#L348). I managed to build msbuild. However, when trying to package a simple library like https://github.com/protobuf-net/protobuf-net, it fails with:

   Project "/tmp/guix-build-protobuf-net-2.4.5-1.706684b.drv-0/source/src/protobuf-net/protobuf-net.csproj" (2) is building "/tmp/guix-build-protobuf-net-2.4.5-1.706684b.drv-0/source/src/protobuf-net/protobuf-net.csproj" (2:3) on node 1 (Build target(s)).

   Seems that Nuget needs to run, but maybe fails because of the lack of network. Any clue what to do about this? It seems to be trying to build Debug/net461, so maybe if I somehow provided this as input it would not try to build it.

2 .Another error which stands out is

The RuntimeIdentifierGraph.json file is in the source but is not included in the final package. Any clue why?
