About

Microsoft Agent Framework (14,091 GitHub stars, MIT) is the official successor to AutoGen (which is in maintenance mode): enterprise-ready agents for Python and .NET with workflows, middleware, and deep Azure/OpenAI integration.

Actively maintained (pushed Oct 2026). The 1.0 release marked it production-ready. For teams on the Microsoft stack building multi-agent systems, this is the current answer — new projects should start here, not AutoGen. Migration guide from AutoGen on learn.microsoft.com.

What it can do

  • • Multi-agent orchestration (successor to AutoGen)\n• Workflows with middleware and observability\n• Python and .NET support\n• Deep Azure/OpenAI integration\n• Enterprise-ready (1.0)\n• Migration path from AutoGen

Setup

  1. Install: pip install agent-framework (Python) or NuGet (dotnet).\n2. Configure your model client (Azure OpenAI, OpenAI).\n3. Define agents and workflows; run with middleware.\nSee https://learn.microsoft.com/agent-framework for migration and guides.
