dotnet 8.0 support?

[Pixel-Tony]

This is a wonderful project, although I hadn't got too familiar with it yet, but I see a lot of potential for support too.
Yet, in my opinion, jumping to pre-release version is a bit overkill. Maybe we can add support for 8.0, until 9.0 is in release? I tried building with 8.0 as target and got no errors.

When I was developing this framework, the results generated from the JSON source had a bug and couldn't run properly under AOT. It wasn't until I upgraded to dotnet9 that it could run normally, possibly because my local dotnet8 version wasn't high enough.

You might be right, I'll try to release a version that supports dotnet8, but I can't guarantee its correctness, as I've only run my project on dotnet9.

You can install it on NuGet in a few minutes.
