Summary
Microsoft Agent Framework consolidates two separate AI orchestration libraries into one system for building multi-agent workflows that coordinate, call tools, and integrate with enterprise services. The problem: organizations already using Semantic Kernel or AutoGen face fragmented APIs and maintenance uncertainty as both libraries enter long-term support mode. The consolidation offers dual-language support (Python and C#) with consistent interfaces, built-in OpenTelemetry tracing, and seamless Azure/Microsoft 365 hooks—advantages for teams locked into the Microsoft stack. The catch: it launched in October 2025 as public preview, meaning APIs and behaviors will shift before a stable release.
Bottom line: *Use this if you're building agents in Azure and need enterprise governance; skip it if you need production stability or multi-cloud flexibility.*
