we have been using Agent Framework. I also have been eyeing LlmTornado. Personally, I find dotnet as a whole hard to implement the kind of abstractions I want to have to make it ergonomic to implement AI stuff.

I've been fiddling around with many prototypes to try to figure out the right way to do this, but it feels challenging; I'm not yet familiar enough with how to do this ergonomically and idiomatically in dotnet haha
