TL;DR We bundled an internal Azure Pipelines task extension into a single bundled JavaScript file using esbuild. The task package dropped from tens of megabytes and thousands of files to three files per task ( script.js ,  task.json , and  icon.png ). The change took about 20 lines of build tooling.

We are excited to announce the public preview of Microsoft Agent Framework for Go, a Go implementation of Microsoft Agent Framework for building, orchestrating, and deploying AI agents and multi-agent workflows. Microsoft Agent Framework is designed for developers who are moving from single prompt calls to production agent systems: agents that use tools, keep context, coordinate with other agents, stream results, and can be observed and governed as part of real applications.

Pure Virtual C++ 2026 is almost here: a free, one-day virtual conference for the whole C++ community, streaming Tuesday, July 21, 2026 at 9:00 AM PT on YouTube (Microsoft Reactor) and Twitch, with on-demand recordings on the Visual Studio YouTube channel afterward. Register now → This is the first post in our three-part Meet the Speakers series. Over the next week we’ll introduce you to the people behind this year’s featured sessions and the problems they’re helping you solve.

Having just tried this tool, yet again, to upgrade a NET Framework to NET Core web API I still think it is pretty bad experience. Let’s start with the enormous amount of markdown files it generates for planning, every task, etc. Every single one of these opens in the VS editor and you have to approve it. It is overwhelming and slow. Moving on to the actual upgrade it really struggles to do even simple things. Upgrading a class library is straightforward and it rarely has issues.

It’s here. Starting today, SharePoint Copilot Apps are in public preview – and they change what Copilot can do for your users. Instead of describing a task in a back-and-forth chat, users can approve an expense, triage an incident, or run an onboarding checklist as a real, interactive app, right inside the Copilot canvas – not a wall of text.

Part 3 of Build your own claw and harness with Microsoft Agent Framework. In Part 2 our personal finance assistant learned to work with your data safely: it reads your portfolio, asks before it trades, and remembers what matters across sessions. It’s useful – but everything it knows is baked into one prompt, it does its work one step at a time, and it can’t reach past the file-access tools to actually reorganize anything.

Introduction: The Problem Media and entertainment teams work with massive asset catalogs for films and TV series. Each asset often includes structured metadata such as episode ID, scene ID, and shot ID, along with the visual content itself. Teams want a unified search experience that understands both metadata constraints and natural language intent.

This blog post summarizes changes to the vcpkg package manager as part of the 2026.06.01 and 2026.06.24 registry releases and the 2026-05-27 tool release. These updates add a vcpkg-tool switch to skip installation when packages are already cached, OpenHarmony (OHOS) platform support, and major library updates including curl 8.21, CGAL 6.2, and Graphviz 15, along with other minor improvements and bug fixes. There are now 2,849 total ports available in the vcpkg curated registry.

Today we are proud to announce the availability of TypeScript 7, a 10x faster native port of TypeScript! Since its early days, TypeScript has promised to deliver on JavaScript that scales. By bringing strong type-checking and rich tooling to the world of JavaScript, TypeScript made it possible to build non-trivial high-quality apps across platforms. Last year, our team unveiled TypeScript’s next step in scaling: making every part of the toolset an order of magnitude faster.

Most “AI agent” demos forget everything the moment the process exits. That’s fine for a toy project, but useless for anything real. An agent that helps you write, triage, or support needs two things a language model alone can’t give it: durable state and the ability to recall the right context by meaning. This post shows how to build exactly that by integrating two pieces that fit together surprisingly well: Eve — Vercel’s filesystem-first agent platform.
