Unpacking the Microsoft Agent Framework
Hello everyone. This is Jon, the blog administrator. Today, I'll be taking a closer look at the Microsoft Agent Framework, a new framework announced by Microsoft in 2025. This framework is a toolkit that makes it easy to create agents (automated software mechanisms) that utilize AI (artificial intelligence). As AI technology evolves, agents are gaining attention as more than just chatbots, capable of automatically completing complex tasks. I'll start with the basics so that even beginners can understand.
Recommended for those who want to start automating with no coding!

What is Microsoft Agent Framework?
The Microsoft Agent Framework is an open-source software development kit (SDK) announced by Microsoft on October 1, 2025. It is a tool for creating and managing AI agents, designed to make it easier for developers to build AI-powered applications. An AI agent is software that automatically performs tasks based on user instructions, such as searching for information, invoking tools, and collaborating with other agents.
This framework integrates two existing Microsoft projects: the Semantic Kernel (a tool for enhancing AI semantic understanding) and AutoGen (a library for building multi-agent systems). This allows developers to efficiently create AI agents using programming languages such as .NET and Python. According to the official blog and documentation, by integrating with Azure AI Foundry (Microsoft's AI development platform), enterprise-level applications can be scaled up.
For beginners, an AI agent is like an "automated AI assistant" that can think for itself and do things like auto-reply emails or analyze data. By using this framework, you can create such an agent with very little code. Incidentally, there is also a service called Gamma, which is an AI-based tool that can instantly create documents and slides. For more details,This articleIt is introduced in the above, so if you are interested, please check it out.
Main features and functions
The appeal of the Microsoft Agent Framework is that it simplifies the development of AI agents. Below are its main features:
- Multi-agent Orchestration: Multiple agents can be linked together to create complex workflows. For example, you can easily set up a workflow where one agent collects data and another analyzes it.
- Ease of tool integration: Supports standards such as MCP (Microsoft Copilot Protocol), A2A (Agent-to-Agent), and OpenAPI, allowing you to call external APIs (Application Programming Interfaces) to extend functionality.
- Observability: Use OpenTelemetry to monitor and log agent behavior, allowing you to quickly identify the cause of any issues.
- Human-in-the-loop: Incorporate human approval into agent decisions, increasing safety.
- Open Source: Free for anyone to use and contribute to. Published on GitHub and incorporating community feedback.
These features were highlighted in announcements on the Azure blog and the .NET blog on October 1, 2025. The key point is that developers can use them to quickly deploy AI agents into production environments.
Benefits for developers
The framework is aimed at developers of all levels. Beginners can easily get started with a drag-and-drop-like interface, while advanced developers can customize it to their liking. According to an InfoQ article (published October 2, 2025), the combination of the stability of the Semantic Kernel and the innovative ideas of AutoGen makes building AI agents more efficient.
Latest Updates and News for 2025
The Microsoft Agent Framework was released as a preview on October 1, 2025. CEO Satya Nadella's post (October 1, 2025) emphasized its enterprise potential, stating that "the economics of AI depend on efficient token factories and high-performance agent frameworks."
Looking back chronologically:
- November 2025, 10: Official announcement on Azure blog and .NET blog. Preview version released.
- November 2025, 10InfoQ and Microsoft Learn have detailed overviews explaining the integration of the Semantic Kernel and AutoGen.
- 2025 year 10 month 4 day to 10 day: Comprehensive reviews have appeared in several articles on Medium (e.g., Henry Bravo's post), reporting that General Availability (GA) was reached on October 2nd.
- November 2025, 10: TuringPost's X post mentions private preview of enterprise multi-agent.
There has been active discussion in the developer community on X (formerly Twitter), with many saying it will become the new standard for agent development. Technical blogs like F# Weekly (October 4, 2025) have also featured it as an update for .NET developers. This information is based on official sources and reliable media.
Summary and future prospects
The Microsoft Agent Framework is a tool that democratizes the development of AI agents, symbolizing the AI trends of 2025. It is open source and easy to access, and its integration with Azure makes it suitable for large-scale applications. If you're interested in AI, we recommend starting by trying it out using the official documentation.
Gamma is perfect for those who want to streamline document creation using AI, like an AI agent. For more information,This article .
In summary, I think this framework is a step towards bringing the future of AI closer to us. If developers can easily create agents, the use of AI in everyday life and business will become even more widespread. However, please be sure to always check the latest information and use it safely.
