I struggled to get started. For ages, I kept putting off building this website, creating a new programming language for Visual Studio, and coming up with fresh color themes. Each project looked overwhelming, and I couldn’t find the time or motivation to jump in. It all just felt like...

The destructor serves as the "finally".

Delivering high-quality software requires clarity, speed, and collaboration. That’s why we introduced the New Test Run Hub in Azure Test Plans. A modern, streamlined experience designed to make test execution and analysis fast and intuitive. And we’re excited to announce that this...

Security vulnerabilities don't fix themselves. Someone needs to track them, prioritize them, and actually ship the fix. If you've ever tried to manage security alerts alongside your regular sprint work, though, you know the friction: you're looking at an alert in one tab, switching to...

It's a placeholder because the shortcut is to an MSI application.

Azure AI Foundry is now Microsoft Foundry. Read the latest announcements about agents, models, tools and more.

1. Introduction AI coding agents/assistants such as GitHub Copilot have become common in modern software engineering workflows. Their strengths—rapid pattern completion, context-aware suggestions, and the ability to learn style from local code—stem from broad training on large...

Email is a key part of how people get things done, whether it’s booking a reservation, confirming a package delivery, or managing a cab reservation. But as inboxes become increasingly cluttered, important transactional information often gets buried. Users are forced to open multiple...

In November, we introduced C++ code editing tools for GitHub Copilot as a Private Preview, focusing on partnering with customers to tackle one of the common, taxing challenges for C++ development: refactoring at scale. Since then, we've listened to feedback and refined our tooling to make...

In our previous blog we introduced Azure Command Launcher for Java (jaz) —a safe, resource-aware way to launch the JVM without hand-tuning dozens of flags. This follow-up shares performance results, focusing on how jaz affects G1 behavior, heap dynamics, and pause characteristics under...

Azure DevOps enhanced support for Microsoft.Testing.Platform, from running tests to publishing results!

It starts the way these things always start.  A red build. A failing test. And that quiet, sinking feeling of “This worked yesterday.”  Meet Sam. Sam’s not a junior, not a rockstar, just a solid developer who’s shipped enough code to know that bugs don’t care how...

Something is forcing it down an alternate path.

A few months ago we introduced the Azure Boards integration with GitHub Copilot in private preview. The goal was simple: allow teams to take a work item from Azure Boards and send it directly to GitHub Copilot so the coding agent could begin working on it, track progress, and generate a...

With introduction of MCP support, it’s now much easier for developers to integrate their business workflows, SaaS, and LoB systems into Copilot via declarative agent.

Here on the Visual Studio team, our top priority is making your coding experience smoother and more enjoyable. And that begins with truly listening to your feedback. We understand that sometimes sharing your thoughts can feel like tossing bug reports and suggestions into a black hole. It...

When the journey is not half of the fun.

Who goes first?

In the new year, we’ll be retiring the Global Personal Access Token (PAT) type in Azure DevOps. Global PATs allow users to authenticate across all accessible organizations. While this can feel convenient, a single credential with broad reach creates a concentrated security risk —...

As someone who lives and breathes in the command line, I love making my terminal feel like home. Windows Terminal is full of personalization options that really allow for a custom experience. Additionally, I can stay within my terminal for my development with GitHub Copilot with the...

Aspire provides a *batteries included* approach through **integrations**

If they don't match, then the 8-bit strings are basically broken already.

The Azure Cosmos DB Linux-based vNext emulator (preview) is a local version of the Azure Cosmos DB service that runs as a Docker container on Linux, macOS, and Windows. It provides a cost-effective way to develop and test applications locally without requiring an Azure subscription or...

For years, “Database” and “Search systems" (think Elastic Search) lived in separate worlds. While both Databases and Search Systems operate in the same domain (storing, indexing and querying data), they prioritized different aspects. OLTP Databases prioritized Structured and...
