Dotnet project reference

Help
1

I am struggling to include a project reference in my c# application when building the nix package.

buildInputs can be used to resolve ProjectReference project items. Referenced projects can be packed with buildDotnetModule by setting the packNupkg = true attribute and passing a list of derivations to buildInputs. Since we are sharing referenced projects as NuGets they must be added to csproj/fsproj files as PackageReference as well.

Do I have to package the referenced project as a separate nix package? Or as a derivation? I tried adding:

<ProjectReference Include="../foo/mydependeny.csproj" />
    <PackageReference Include="mydependeny" Version="*" Condition=" '$(ContinuousIntegrationBuild)'=='true' "/>

But it did not work by itself. If I exclude the project reference alltoghether (build/package my app using only Nuget packages) it works fine.

Current package.nix:

{
  lib,
  stdenvNoCC,
  buildDotnetModule,
  fetchFromGitHub,
  dotnetCorePackages,
  makeDesktopItem,
  copyDesktopItems,
  makeWrapper,
  alsa-lib,
  lttng-ust,
  numactl,
  xorg,
  udev,
  nativeWayland ? false,
}:

buildDotnetModule rec {
  pname = "my-project";
  version = "0.1.1";
  src = ./proj-root;

  packNupkg = true;
  projectFile = "./qufx/qufx.csproj";
  nugetDeps = ./deps.json;

  dotnet-sdk = dotnetCorePackages.sdk_9_0;
  dotnet-runtime = dotnetCorePackages.runtime_9_0;

  nativeBuildInputs = [
    copyDesktopItems
    makeWrapper
  ];

  runtimeDeps = [
    yt-dlp
    alsa-lib
    lttng-ust
    numactl
    xorg.libXi
    udev
  ];

  executables = [ "qufx" ];

  meta = {
    description = "qufx";
    homepage = "https://github.com/";
    license = lib.licenses.gpl3Only;
    maintainers = with lib.maintainers; [ neurofibromin ];
    platforms = [ "x86_64-linux" ];
    mainProgram = "qufx";
  };
}
