Microsoft build keynote 2025 : AI agents era and what you need to know!

Yesterday took place at Seattle the keynote for the Microsoft Build 2025, here are my highlights about what I think important.

Post written with love and without any help from AI.

The Agents are here

This is really the age of the AI Agents. After the copilots were generative AI and models, here the agents can do things for you and take actions. Now the idea is to develop those agents, coordinate them and they can be integrated directly into Windows 11.

More precisely, we now have the general availability of Azure AI Foundry to orchestrate specialized agents for more complex tasks leveraging Semantic Kernels, MCP (Model Context Protocol).

About security, now in preview, agents developed in Microsoft Copilot Studio or Azure AI Foundry ara automatically assigned a unique identity in Microsoft Entra ID. What is so great? Because we can assign roles and permissions to those identity like any other app in Azure bringing more security and control.

Pushing forward to MCP and the open Agentic Web

MCP is and will continue to be the standard for AI Agents with more investments from Microsoft, be part of the MCP Steering committee. Moreover, Microsoft has released MCP Server registry service for entities (think about a large company who wants to centralize its own developed MCP).

A new open project called NLWeb which makes it easy for websites to provide a conversational interface for their user with any model and data. You can see this project as a communication standard between MCP servers and a website when it comes to grab data from any website, doing search or perform actions directly to the site. Uses cases are endless for new uses cases!

GitHub copilot in VS Code is open source

Copilot Chat extension available under the MIT license aims to foster community-driven development and enhance AI programming experiences.

I see that any individual or organization can customize this agent regarding its own specific needs, helping developers with more productivity, debugging more easily and so on. If the developers use the agent in VS code using the same language from its own company.

GitHub Copilot coding agents

Now you can assign an issue to the GitHub agent and it will work for you !

This agent will do the job (you can see it live), create a PR like a real person and you can add a comment if you are not happy with the result.

The videos exposed during the conference are very impresive and this will help developers but in other hand, it will bring more difficulties because we will not be used to think more and i fear about the knowledge of the future developers. But it's another discussion...

Be careful, this is in preview and you must have the Pro+ licence.

WSL is now Open source

Windows Subsystem for Linux is now open source on GitHub providing the community to directly participate in the project, providing WSL to be more robust and widely used.
