Hey gang, I'm trying to build https://github.com/aaru-dps/Aaru/releases/tag/v6.0.0-alpha.12 from source (e2d70ba327dfc5ab67d068389c0b2e6049f76a87) and keep getting the following issue. The issue does not seem to appear with the latest git commit (5e8aece987d799e51e970bd170c28e2bd1ebf374) -- Anyone have any ideas on where to go from here?

CSC : error PH2075: AssemblyVersion has changed. Actual: 6.0.0.12 Expected: 1.0.0.0 [/build/source/Aaru.Logging/Aaru.Logging.csproj]

I'm using nixpkgs for years now, and dotnet for the first time. I need to package a web service somepkg that a third party offers on their own nuget server nuget.thirdparty.com/somepkg/nuget. I can't figure out how to properly override buildDotnetGlobalTool (I guess) to accept the custom nuget url. I'm trying something like this:

buildDotnetGlobalTool.override ({
  fetchNupkg = dotnetCorePackages.fetchNupkg.override {
    url = "..."

But that seems to be wrong:

error: function 'anonymous lambda' called with unexpected argument 'url'
       at /nix/store/jbjpzwqzf0vq989s6y302jy1dff4z321-source/pkgs/build-support/dotnet/fetch-nupkg/default.nix:1:1:

Is there a standard way to do this? (Or else I probably need to dig deep into how dotnet is implemented in nixpkgs?)

I managed something like this:

let
  pname = "IBPkernelSimplifiedHS";
  version = "v1";
  customNugetServer = "https://nuget.thirdparty.com/somepkg/nuget";
  url = "${customNugetServer}/${pname}/${version}";
in
dotnetCorePackages.buildDotnetGlobalTool.override {
  fetchNupkg = args: dotnetCorePackages.fetchNupkg (args // {
    inherit url;
  });
} {
  inherit pname version;
}

And it actually attempts to download from the third party server 🎉 but the URL schema is still wrong. I'm not sure what the standard url schema would be in this case.

I managed to grasp the URL schema, so that's fixed. I now have have a somepkg.nupkg archive with this structure:

_rels -> .rels
_lib -> net8.0 ->
  somepkg.dll
  somepkgFoo.dll
  ...
package ->
  services -> metadata -> core-properties -> 12341234.psmdcp
  [Content_Types].xml
somepkg.nuspec

It seems that buildDotnetGlobalTool can't deal with this structure:

Unhandled exception: System.IO.DirectoryNotFoundException: Could not find a part of the path '/nix/store/58w6rl6al5f1yq4ckmg4qm7a8r1r7rz9-somepkg-1.0.98/lib/somepkg/.store/somepkg/1.0.98/somepkg/1.0.98/tools
