I've been trying to package a dotnet 6 application and having issues with the Microsoft.Build.NoTargets SDK, if I pin the version in the .csproj the build fails during dotnetConfigureHook with error : Unable to find package Microsoft.Build.NoTargets. No packages exist with this id in source(s): nugetSource, if I leave it unpinned it seems to find it until it fails during dotnetBuildHook with error MSB4236: The SDK 'Microsoft.Build.NoTargets' specified could not be found.

I'm fairly new to nix and very unfamiliar with dotnet development (I was not involved in the actual development of this application), so I would appreciate some pointers as I'm out of ideas

In reply to @magikarpz:matrix.org
are you able to share the source code to this app? and the nix code?

Here's the source code of the application: https://github.com/Assistant/Hive
The nix code currently lives only in my nixos config with this file being called by callPackage,

{
  lib,
  fetchFromGitHub,
  buildDotnetModule,
  dotnetCorePackages,
  mono,
  dotnet-sdk,
  openssh,
}:
buildDotnetModule rec {
  fullSrc =
    (fetchFromGitHub {
      owner = "Assistant";
      repo = pname;
      rev = "66649a2a343797a98f3228172ffc17052f5442d1";
      sha256 = "sha256-iG49/XLi3Skhp8NY5IAqSU5IfMj4y4GNIm2huewiu9Q=";
      fetchSubmodules = true;
    })
    .overrideAttrs (_: {
      GIT_CONFIG_COUNT = 1;
      GIT_CONFIG_KEY_0 = "url.https://github.com/.insteadOf";
      GIT_CONFIG_VALUE_0 = "git@github.com:";
    });

  pname = "Hive";
  version = "0.0.1";
  src = fullSrc;

  projectFile = "Hive.sln";
  nugetDeps = ./deps.nix;
  selfContainedBuild = true;
  # dotnetInstallFlags = ["--framework" "net6.0"];

  # dotnet-sdk = dotnetCorePackages.sdk_6_0;
  # dotnet-runtime = dotnetCorePackages.aspnetcore_6_0;

  nativeCheckInputs = [mono dotnet-sdk];
  # buildInputs = [openssh];
  # testProjectFile = "src/Hive.Test/Hive.Tests.csproj";

  meta = with lib; {
    homepage = "https://github.com/Atlas-Rhythm/Hive";
    description = "A general backend project for modding communities";
    license = licenses.agpl3Only;
  };
}

Ruri: managed to make it compile with the following code:

{
  lib,
  fetchFromGitHub,
  buildDotnetModule,
  dotnetCorePackages,
  mono,
  dotnet-sdk,
  openssh,
}:

buildDotnetModule rec {
  fullSrc =
    (fetchFromGitHub {
      owner = "Assistant";
      repo = pname;
      rev = "66649a2a343797a98f3228172ffc17052f5442d1";
      sha256 = "sha256-iG49/XLi3Skhp8NY5IAqSU5IfMj4y4GNIm2huewiu9Q=";
      fetchSubmodules = true;
    })
    .overrideAttrs (_: {
      GIT_CONFIG_COUNT = 1;
      GIT_CONFIG_KEY_0 = "url.https://github.com/.insteadOf";
      GIT_CONFIG_VALUE_0 = "git@github.com:";
    });

  pname = "Hive";
  version = "0.0.1";
  src = fullSrc;

  nugetDeps = ./deps.nix;

  dotnet-sdk = dotnetCorePackages.sdk_6_0;
  dotnet-runtime = dotnetCorePackages.aspnetcore_6_0;

  dotnetInstallFlags = [ "--framework" "net6.0" ];
  #testProjectFile = "src/Hive.Test/Hive.Tests.csproj";
