Great this repo is not dead. :)

Hello,
Indeed I am still using your Nuget Package, and I am glad that you continue working on it. :)

Thanks will be doing some more updates in a few weeks to handle functions and possibly a few other features that have since been added to the API. Also looking for contributors if you or anyone else is interested.

Function calls would be awesome, as well as the assistance part (but I am hesitant to implement it myself because it's still in beta, and it doesn't seem very user-friendly yet.)
Contributing: I know the best software is the one you write yourself, but there are some alternatives on GitHub, like https://github.com/betalgo/openai. Maybe you should direct your efforts to this repo?
I chose your package a couple of months ago because my code was looking nearly identical to yours, so I stopped coding and opted for your package instead.
I think I can't contribute much, perhaps if I find some weird stuff, but your code seems very neat with high standards.
