Currently (10/17/2022) IMO there is no acceptable answer to this as the code for such may no longer be maintained, was not completely tested, etc.

Also when searching for an answer to this consider using the keyword `.NET` or `interop` or such instead of `CSharp`.

Baring an acceptable answer here is some related info:

- [Windows InteropServices for libswipl.dll](https://swi-prolog.discourse.group/t/windows-interopservices-for-libswipl-dll/4409)
- By Uwe Lesta
  - [SWI-Prolog interface to C# and F#](https://www.swi-prolog.org/contrib/CSharp.html)
  - [Swi-cs-pl - A CSharp class library to connect .NET languages with SWI-Prolog - Table of Content](http://www.lesta.de/prolog/swiplcs/Generated/Index.aspx)

- [Package “swicli”](https://www.swi-prolog.org/pack/list?p=swicli)
- [NuGet Gallery | SWI.Prolog 1.1.5990](https://www.nuget.org/packages/SWI.Prolog) - Never tried it. Not sure if it can talk to SWI-Prolog but it is a [NuGet](https://www.nuget.org/) package so someone put it there for a reason.

Normally I would add HTH but in this case I think these will all be dead ends.
