为什么值得关注
The .NET 1.21.0 release of the Microsoft Agent Framework brings multiple breaking changes and dependency modernizations. Key breaking modifications include relocating line-numbering contracts to AgentFileStore with added file access read lines, clarifying Agent-to-Agent (A2A) run modes, isolating the LocalCodeAct subprocess environment, and restricting MCP skill archives exclusively to the ZIP format across .NET and Python. Additionally, the Azure.AI.OpenAI dependency was removed in favor of updated integrations, Azure.AI.Projects was updated to 3.0.0-beta.2, and AWSSDK.Extensions.Bedrock.MEAI was replaced with AWS.Bedrock.MEAI. Security and execution enhancements include fixing redirect header forwarding, canonicalizing Hyperlight sandbox fingerprints, scoping OpenAI hosting storage by isolation keys, and applying Hyperlight-style approvals to LocalCodeAct.
