adding clingo-cs to a C# project?

Hi Rafael,

Thank you for all your work making clingo-cs! I'm very interested in combining C# and Clingo. When clingo-cs is added to a project, will I then be able to follow the Python API example? Something like:

using Clingo-cs;
var ctl = clingo.Control()
ctl.add("base", [], "p(@id(10)). q(@seq(1,2)).");
ctl.ground([("base", [])], context=Context());

I've taken the following steps:

1. downloaded clingo-cs from github as ZIP
2. downloaded clingo-5.5.1, renamed it to "clingo", and placed it in clingo-cs-main
3. created clingo\build\win and clingo\build\linux
4. .\build.ps1 (success!)
5. dotnet build --configuration Debug (partial success?)

clingo-cs-main\src\Clingo_cs\bin\Debug contains:
Clingo_cs.0.1.0.nupkg (11kb)
net6.0 (directory)

The net6.0 directory contains:
Clingo_c.dll (10kb)
Clingo_c.pdb (12kb)
Clingo_cs.deps.json (1kb)
Clingo_cs.dll (17kb)
Clingo_cs.pdb (17kb)
ref (directory)

The ref directory contains:
Clingo_cs.dll (10kb)

In Visual Studio, I created a package source entry for clingo-cs-main\src\Clingo_cs\bin\Debug and when I open Nuget and use this source, I see the option to install a single package:

Clingo_cs by Rafael Alcalde Azpiazu A C# bindings to the clingo library.

When I select that package, I see the following errors:

• Package restore failed. Rolling back package changes for 'dle_clingo_cs_test' (my project)
• NU1101 Unable to find package Clingo_c. No packages exist with this id in source(s): Local Clingo_CS, Microsoft Visual Studio Offline Packages dle_clingo_cs_test dle_clingo_cs_test\dle_clingo_cs_test D:\Documents\Programming\CSharp\dle_clingo_cs_test\dle_clingo_cs_test\dle_clingo_cs_test.csproj

Here are the detailed results of the build:

Building on Windows looks for /bin/linux?

I tried building clingo-cs on Mac, but ran into issues where it was looking for a .so library but Mac had built a .dylib. I wasn't sure how to fix this so I tried building on Windows - this results in the following error when performing the dotnet step:

C:\Program Files\dotnet\sdk\7.0.400\Sdks\NuGet.Build.Tasks.Pack\build\NuGet.Build.Tasks.Pack.targets(221,5): error : Could not find a part of the path 'D:\clingo-cs\clingo\build\linux\bin'. [D:\clingo-cs\src\Clingo_c\Clingo_c.csproj]

The linux/bin folder doesn't exist becuase it's built a windows/bin folder instead - I'm not sure why the dotnet step is trying to find a Linux library.
