Possibly missing source packages?

[pombredanne]

Using this Sample.csproj.txt file (renamed to /Sample.csproj) :

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net5.0</TargetFrameworks>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Castle.Core" Version="5.1.1" />
    <PackageReference Update="Microsoft.Extensions.Configuration.Binder" Version="7.0.0" />    
  </ItemGroup>
</Project>

I run the inspector and I get this output:

sample.json.txt

1. there are no "sources_packages"
2. the homepage_url listed here is often the source repo URL:
   • 'pkg:nuget/Microsoft.NETCore.Platforms@3.1.0', 'https://github.com/dotnet/corefx': no source repo, but the homepage_url is a repo and this the same in all API endpoints and its nuspec for this version (this may be different for other versions) ... and even if we had a source repo, there would be an issue as to figure which part of the sources are used in https://github.com/dotnet/corefx/releases/tag/v3.1.0 (which is further more archived)
   • 'pkg:nuget/System.Security.Principal.Windows@4.7.0', 'https://github.com/dotnet/corefx', same as above
   • 'pkg:nuget/System.Security.AccessControl@4.7.0', 'https://github.com/dotnet/corefx', same as above
   • 'pkg:nuget/Microsoft.Win32.Registry@4.7.0', 'https://github.com/dotnet/corefx', same as above
   • 'pkg:nuget/System.Diagnostics.EventLog@4.7.0', 'https://github.com/dotnet/corefx', same as above
   • 'pkg:nuget/Castle.Core@5.1.1', 'http://www.castleproject.org/': here none of the API endpoint seem to have anything but https://www.nuget.org/packages/Castle.Core lists a source repo as does the nuspec at https://api.nuget.org/v3-flatcontainer/castle.core/5.1.1/castle.core.nuspec but this is empty in the catalog entry https://api.nuget.org/v3/catalog0/data/2022.12.30.09.24.25/castle.core.5.1.1.json

So this is a bit messy and there is no easy way to get something clean

Things are messy and incomplete at best as provided by the NuGet API!

There could be something extra we could do when this is available in the .nuspec at the cost of an extra (expensive) API call and/or we could come with heuristics when the homepage/project URL is @ Github
