Microsoft Agent Framework
Microsoft
Microsoft's new multi-language agent framework for building, orchestrating, and deploying agent workflows.
Curated by Tiberiu ArvaStale
Strengths
- Multi-language SDKs
- Python and .NET support
- Graph-based workflows and DevUI
Practitioner note
Worth watching for teams standardising on Microsoft agent patterns, but adoption should still be treated as early and architecture-led.

Risk tier: Not applicable · as of 2026-08-23Source-backed information mapped from Microsoft Agent Framework's tracked risk tier — not legal advice. Obligations depend on how your organisation deploys the system; see the full obligation reference and timeline.
This record's EU AI Act risk tier is marked not applicable, so no tier-specific obligations attach. Deployers embedding it in an AI system in scope of the Act should assess that system's own tier.
