Microsoft shipped the most significant framework consolidation of 2026: Agent Framework RC for both .NET and Python, merging AutoGen's agent abstractions with Semantic Kernel's enterprise features into a single programming model. Graph-based orchestration (sequential, concurrent, handoff, group chat), multi-provider support (Azure OpenAI, Anthropic, Bedrock, Ollama), and A2A/AG-UI/MCP interoperability make this the most enterprise-complete agent framework available. GA targets end of Q1. AutoGen and Semantic Kernel are now maintenance-only. Microsoft Foundry Blog
