How to use this library in .NET?

[PeterHevesi]

Hi there :)
I need to use Asio4All in our game that we code in Unity.
We have bought this asset from Unity Store:
https://assetstore.unity.com/packages/audio/sound-fx/low-latency-multichannel-audio-147091

But it is no longer developed or maintained, and it has some issues, so I am thinking of using your repo :)
But it is kinda strange, the name is ASIO4ALL.NET, but when I download it, I only see C++ code in it.

And when I opened the solution, I had some errors..
So how can I use it in .NET? And is it compatible with old .NET Framework 4.8 or with the modern .NETs like .NET 9 for example?
