Project status and general questions

[arvanus]

Hello, I'm starting do learn C# and found this project on Google, but I saw that the last activity was at sep-2020, so I'd like to know how is the project status, is the devs active somehow, is this project forked and maintained by others? Should I start a new project using BotSharp or look for alternatives?

Also, I wasn't sure how is this project different from RASA and Articulate, Thanks for your help!
