Bot Builder SDK

The Bot Builder SDK enables you to build bots that support different types of interactions with users. You can design conversations in your bot to be freeform. Your bot can also have more guided interactions where it provides the user choices or actions. The conversation can use simple text or more complex rich cards that contain text, images, and action buttons. You can add natural language interactions and questions and answers, which let your users interact with your bots in a natural way.

Bot Framework

The Bot Builder includes a set of command line tools to streamline end-to-end conversation centric development experience, and an emulator for debugging your bot locally or in the cloud.
