About Microsoft Agent Framework

Microsoft Agent Framework is a comprehensive .NET library for building, orchestrating, and deploying AI agents and multi-agent workflows. The framework provides everything from simple chat agents to complex multi-agent systems with graph-based orchestration capabilities.

Key Features

  • Multi-Agent Orchestration: Coordinate multiple agents using sequential, concurrent, group chat, and handoff patterns
  • Graph-based Workflows: Connect agents and functions with streaming, checkpointing, and human-in-the-loop capabilities, with both imperative or declarative workflow support
  • Multiple Provider Support: Seamlessly integrate with various LLM providers with more being added continuously
  • Extensible Middleware: Flexible request/response processing with custom pipelines and exception handling
  • Built-in Observability: OpenTelemetry integration for distributed tracing, monitoring, and debugging
  • Cross-Platform: Compatible with .NET 8.0, .NET Standard 2.0, and .NET Framework for broad deployment options

Whether you're building simple AI assistants or complex multi-agent systems, Microsoft Agent Framework provides the tools and abstractions needed to create robust, scalable AI applications in .NET.
