Microsoft Announces Framework for Building Agent-Based AI Apps
Hi everyone. This is Jon. The world of AI is evolving every day, and Microsoft recently made an interesting announcement. It's an open-source framework called the "Microsoft Agent Framework," which will be released around October 1, 2025. This tool makes it easy to create apps that utilize AI agents (software components that autonomously execute tasks), and it looks like it will be a great help to developers. An agent is not just a chatbot; it's an advanced AI that can think up goals, call tools, and collaborate with other agents. Even beginners can use this framework to easily build complex AI systems.
Recommended for those who want to start automating with no coding!

Background and timing of the announcement
On October 1, 2025, Microsoft announced "Introducing Microsoft Agent Framework" on the official Azure blog. This is an open-source SDK (software development kit) to simplify the development of apps that utilize AI agents. An SDK is a collection of tools that programmers use to create apps. This framework integrates AutoGen, a Microsoft research project, with the Semantic Kernel, an enterprise platform, and enables the construction of multi-agent systems using the .NET and Python programming languages. Multi-agent refers to a system in which multiple AI agents work together.
A few days after the announcement, on October 2 and 3, 2025, technical media outlets such as InfoWorld and InfoQ reported details. For example, an InfoWorld article noted that the framework makes it easy to create complex workflows. Microsoft CEO Satya Nadella also posted on X (formerly Twitter) on October 1, 2025, emphasizing that "the AI economy depends on efficient token factories and high-performance agent frameworks." This has generated a lot of buzz in the development community.
These advances in AI tools can also be useful for everyday tasks like document creation. For example, if you want to learn about Gamma, a new standard that uses AI to instantly create documents, slides, and websites, check out this article:What is Gamma? The new standard for instant document, slideshow, and website creation using AI [2025 Edition]Gamma has a similar appeal to Microsoft's framework in that it allows you to use AI without coding.
Main features of Microsoft Agent Framework
The appeal of this framework is that it allows you to create, adjust, and deploy AI agents all in one place. To put it simply for beginners, an AI agent is like a robot that thinks autonomously, and by using this framework, you can create an app by linking multiple such agents together. According to the official announcement, the following features are included:
- Multi-agent Orchestration: A system in which multiple agents cooperate to complete a task. For example, one agent can gather information while another analyzes it.
- Workflow ManagementGraph-based orchestration allows you to add conditional branching and checkpoints. Workflow refers to the flow of work, and allows you to create complex logic without programming.
- Human-in-the-loop: A system in which AI confirms its decisions with a human, improving safety and preventing malfunctions.
- Memory and observation functions: The ability for agents to remember past interactions and monitor the state of the system, allowing for smarter AI apps.
- Integration with Azure AI Foundry: Easily deploy on Microsoft's cloud service, Azure, so you can experiment locally before moving to a production environment.
These features are detailed in a .NET Blog post dated October 2, 2025, and are designed to increase developer productivity. The X post also notes that Microsoft Research has previously introduced tools based on AutoGen, and that this framework is an evolution of that.
Supported languages and open source benefits
The framework supports .NET and Python, making it accessible to a wide range of developers. Open source means that anyone can view and modify the code for free, and improvements by the community are expected. An Azure blog post dated August 13, 2025, lists search agents and collaborative agents as use cases for Agentic AI, and this framework makes it easy to implement such things.
Benefits and Use Cases for Developers
The introduction of this framework will accelerate the development of AI applications. Building AI agents has traditionally required advanced knowledge, but this will make it easier for beginner developers to get involved. The benefits are summarized in bullet points:
- Simplification: Combining AutoGen's research elements with the stability of the Semantic Kernel, it allows for a smooth transition from experimentation to production.
- Scalability: Supports large-scale systems and can be scaled up using Azure.
- Observability: Built-in tools for monitoring agent behavior make debugging easy.
- Diverse use cases: For example, it can be used in practical applications such as automating customer support and integrating data analysis.
As an example of its use, a demonstration of an AI agent performing code generation and task management was shown at Microsoft Build on May 19, 2025. In a post on X, Brett Adcock gave examples of a similar agent framework for browser operation and order processing, demonstrating that Microsoft's framework is suitable for real-world tasks.
Future outlook and points to note
In an InfoQ article dated October 3, 2025, Microsoft stated that it released this framework as a preview. They plan to gather feedback and add features in the future for the official version. AI is evolving rapidly, so developers should regularly check the official documentation. Please note that while it is open source, please check the license before using it for commercial purposes.

In summary, from Jon's perspective, the Microsoft Agent Framework is a groundbreaking tool that lowers the barriers to AI development. By making agent technology more accessible, the use of AI in business and everyday life is likely to expand. I recommend trying it out on the official website first.
