Microsoft Agent Framework
Microsoft's framework for building production-grade agentic AI on Azure, with Python, C#, and Go SDKs and a GA Agent Harness runtime.
For Azure-centric teams needing production-grade agent orchestration, Agent Framework is a solid bet—the GA harness and Go support show momentum. But if you're not on Azure or want open-source flexibility, you'll feel locked in. Choose it for structured workflows; skip it for lightweight experiments. For a more portable option, consider LangChain; for a lower-code alternative, look at Microsoft Copilot Studio.

Skip Microsoft Agent Framework if you're not heavily invested in Azure, need a low-code builder, or want extensive third-party integrations out of the box.
You'll need an Azure subscription for hosting and services, which bills separately based on usage.
The framework itself is free and open-source, but you pay for Azure resources. Compared to LangChain (free, open-source) you pay for Azure; compared to proprietary platforms like LangSmith, you might save on platform fees. It fits Azure-centric enterprises that already budget for cloud costs.

About Microsoft Agent Framework
Microsoft Agent Framework is a developer-first platform for building production-ready agentic AI systems deeply integrated with Azure. It guides you through seven stages from creating your first agent to hosting at scale, with tutorials covering your first agent and tools, multi-turn conversations, memory and persistence, workflows, the Agent Harness, and hosting. The framework supports multi-turn conversations, memory management, workflow execution with orchestrations and checkpoints, and human-in-the-loop workflows. It integrates with Microsoft's Durable Extension for reliable background execution and the A2A (Agent-to-Agent) protocol for inter-agent communication. You can customize agents with tools and skills, and extend behavior with middleware. The Agent Harness, now generally available, provides a runtime for execution and management. SDKs are available for Python, C#, and Go, with sample repos on GitHub. Migration guides are available for teams moving from Autogen or Semantic Kernel. Compared to open-source alternatives like LangChain, Agent Framework offers tighter Azure integration and a more opinionated structure for enterprise scenarios, but at the cost of portability and community breadth.
Behind the Verdict
Microsoft Agent Framework is a structured, developer-centric framework for building agentic AI on Azure. Its biggest strength is the full lifecycle coverage: from first agent to hosting, with a clear seven-stage path. The recent GA of the Agent Harness runtime is a significant milestone, bringing a production-grade runtime for execution and management. The framework also excels in stateful workflows, with checkpoints, resuming, and human-in-the-loop support, which are critical for complex, auditability-focused applications. Integration with Azure Functions and the Durable Extension enables scalable background execution, and the A2A protocol standardizes inter-agent communication. The multi-language support (Python, C#, Go) widens its appeal to teams with varied stacks. However, the framework is tightly coupled to Microsoft's ecosystem, so if you're not on Azure, you'll face friction. Its integration depth with non-Microsoft services is minimal, and the community breadth is smaller than open-source frameworks like LangChain. The Go SDK is new, so examples may be sparse compared to Python or C#. It's also not a low-code tool; you need solid coding skills. For enterprise developers already invested in Azure, it's a compelling choice; for those wanting portability or community-driven innovation, it may feel limiting.

Real-world workflow fit
Concrete scenarios for the personas Microsoft Agent Framework actually fits — and what changes day-one when you adopt it.
Building a customer support agent that needs to handle multi-turn conversations and escalate to human agents
Outcome: You set up the agent using the tutorials, configure human-in-the-loop workflows, and deploy to Azure Functions for scalable hosting.
Porting an existing agent to the Agent Framework
Outcome: You follow the migration guide to adapt your code, leverage the Agent Harness for runtime, and integrate Durable Extension for reliable background execution.
Orchestrating multiple agents for supply chain optimization
Outcome: You use the A2A protocol for inter-agent communication, implement workflows with checkpoints, and host the system on Azure for stateful, auditable operations.
Use Cases
- Build a customer support agent that handles multi-turn conversations and escalates to human agents
- Create a code review agent that analyzes pull requests and suggests improvements
- Orchestrate a fleet of agents for automated data pipeline management
- Develop a personal assistant agent that integrates with Microsoft 365 to manage calendars and emails
- Implement a multi-agent workflow for supply chain optimization
- Build a research assistant that summarizes documents and answers follow-up questions
Models Under the Hood
as of 2026-09-15
Limitations
- The framework is developer-oriented, requiring the Steps 1-7 learning path starting with Python or C# samples.
- It is documented primarily via Microsoft Learn, with migration guides from AutoGen and Semantic Kernel.
- Deep integration is centered on Microsoft/Azure services (Azure Functions, durable hosting, Azure OpenAI).

Where the pricing makes sense
The company stage and team size where Microsoft Agent Framework's pricing actually pencils out — and where peers do it cheaper.
The framework itself is free and open-source, but you pay for Azure resources. Compared to LangChain (free, open-source) you pay for Azure; compared to proprietary platforms like LangSmith, you might save on platform fees. It fits Azure-centric enterprises that already budget for cloud costs.
Setup time & first value
How long it actually takes to get something useful out of Microsoft Agent Framework — broken out by persona, not the marketing-page minute.
For a basic agent with tools, expect a few hours (following steps 1-2). With multi-turn and memory, add a day. For full workflow and hosting, plan for a few days to a week, especially if migrating from another framework.
Switching to or from Microsoft Agent Framework

- →From Autogen: Follow the migration guide on Microsoft Learn to port your agents.
- →From Semantic Kernel: Use the provided migration guide to transition projects.
- ↗To LangChain: You'll need to rewrite orchestration logic and adapt to a different ecosystem, as there is no direct migration tool.
- ↗To Semantic Kernel: You can leverage the migration guide in reverse, but expect manual adjustments.
