About Bot Framework SDK
Bot Framework SDK (often referred to as BotBuilder) is Microsoft's open-source SDK for building conversational AI bots that can be deployed across multiple channels — Microsoft Teams, Slack, web chat, and others — from a single bot implementation.
It provides the conversation-state management, dialog flow, and channel-adapter infrastructure so a bot's core logic is written once and works across whichever messaging channels it's connected to, integrating with Azure AI services for NLU when needed.
Commonly used by teams building bots specifically for Microsoft Teams or other Microsoft-ecosystem-adjacent deployments, given its tight integration with Azure Bot Service.
