What Bot Developer Should Consider

As you know while you would develop bot application you might be needed to integrate other eco-system like adaptive card, hero card and so on to make your bot conversation more interactive. So when you would be using older than asp.net core 2.1 and 3.1 you might need to struggle with them. Moreover, most of the recent release v4.14 has been developed based on asp.net core 2.1. and 3.1. In addition bot samples for customer on Microsoft Official GitHub are developed mostly on asp.net core 2.1 and 3.1. As you can have look on official document here

Hope above information guided you accordingly.
