Multi-targeting fork

[JeremyAnsel]

Hello,
Thank you for this project.

I've created a fork named SharpOpenNat for multi-targeting .Net 8.0, .Net 6.0, .Net 4.8, and .Net Standard 2.0.

• https://www.nuget.org/packages/SharpOpenNat

Why not just submit a PR which adds the additional frameworks?

Resubmitting the same code to nuget under multiple different packages is more confusing for everyone :)

I'd be happy to accept PRs and release a new version of you'd like! Also, are there any features from newer frameworks which you want to use? If not, what's the benefit you're hoping to get from targeting the additional frameworks?

I saw you configured the csproj to use langvesrion 11 even though you're targeting netstandard 2.0. This can produce binaries that don't load under frameworks older than .NET Core 3.0 (i.e. the desktop 4.7.2 / 4.8 framework).

C# 12 is supported only on .NET 8 and newer versions. C# 11 is supported only on .NET 7 and newer versions. C# 10 is supported only on .NET 6 and newer versions.

Technically C# 8 is not fully supported under netstandard 2.0, but as long as you don't use default interface implementations then everything else Just Works.

Hello,
My repository is based on the Open.NAT repository (https://github.com/lontivero/Open.NAT). This repository is based on your Mono.Nat repository (https://github.com/alanmcgovern/Mono.Nat).
The last update of Open.NAT was more than one year ago. It is no longer maintained. The last update of Mono.Nat was more than one year and a half ago. I was thinking it is no longer maintained.
That is why I created my fork. I've published NuGet package and built the api documentation (https://jeremyansel.github.io/SharpOpenNat/api/SharpOpenNat.html).
For the lang version, I use the PolySharp library (https://github.com/Sergio0694/PolySharp). With it you can use a recent C# version in code compiled to run on older .Net runtimes.
