BotSharp

BotSharp is an open source machine learning framework in C# for building AI bot platforms and intelligent assistants.

BotSharp is an open source machine learning framework for building AI bot platforms in C#. It runs on .NET Core as a cross-platform solution designed for enterprise developers integrating artificial intelligence into business systems. The framework involves natural language understanding, computer vision, and audio processing technologies using out-of-the-box machine learning algorithms. It features a modular architecture with a plugin and pipeline flow execution design, supporting multiple user interfaces, data storages, and LLM providers. Developers can manage complex application scenarios through an advanced agent abstraction layer, rich content data structures, and built-in multi-agent conversation state management.
