Microsoft Agent Framework Harness and Hosted Agents Reach General Availability
Quick Answer
Microsoft's Agent Framework has reached general availability, providing a production-ready runtime for multi-agent orchestration, with significant features like built-in OpenTelemetry and a consumption-based billing model.
Quick Take
The framework integrates seamlessly with GitHub Copilot and Claude Agent SDKs, allowing for unified governance and observability across agents, while benchmarks show it halts runaway processes effectively compared to the Copilot SDK.
Key Points
- Agent Framework 1.0 launched on April 2, 2026, after SDK phase.
- Features include function invocation, context management, and built-in OpenTelemetry.
- Integrates with GitHub Copilot and Claude Agent SDKs for seamless orchestration.
- Benchmarks indicate Agent Framework effectively halts runaway processes after 40 iterations.
- Available in .NET and Python on GitHub, with consumption-based billing for hosted agents.
DeepSignal Analysis
What happened
Microsoft's Agent Framework has transitioned to general availability as of April 2, 2026, providing a production-ready runtime for multi-agent orchestration. The framework includes built-in OpenTelemetry and a consumption-based billing model. It integrates with GitHub Copilot and Claude Agent SDKs, allowing for unified governance across agents.
Key evidence
- The Agent Framework reached version 1.0 on April 2, 2026, during the Build 2026 event, which introduced the Agent Harness and Foundry Hosted Agents.
- A benchmark conducted by Microsoft AI principal architect Aqib Sherwani showed that the Agent Framework effectively halted runaway processes after 40 iterations, while the Copilot SDK continued for 300 iterations without stopping.
- The orchestration patterns released alongside the harness support various collaboration styles and share a single API, enabling teams to change coordination methods without rewriting agent code.
Why it matters
The release of the Agent Framework signifies a shift towards a more structured approach to multi-agent orchestration, emphasizing the importance of a supported runtime over mere SDKs. The integration with existing governance and observability frameworks allows for better management of agent behavior and performance. This could enhance the reliability and safety of deploying AI agents in production environments.
