If youve been building local prototypes, internal tools, web backends, or lightweight services on SQL Server Express, you know the routine: its free, familiar, and gets the job done until you hit hardware limits or spend weekends manual backup scripts and handling OS patches. Learn how to upgrade from SQL Server Express to Azure SQL Database free tier in 3 simple steps. Whether you're running SQL Server 2022 (or older) and hitting the hard 10 GB storage wall, or using SQL Server 2025 and realizing 50 GB of disk space doesn't solve the strict 1.4 GB memory bottleneck, staying on Express limits your applica...
Writing and maintaining SQL is easier when you can eliminate repetitive steps and keep your scripts cleanly formatted. With the MSSQL extension for VS Code v1.45, we're introducing the Public Preview of the SQL Formatter alongside the General Availability of Azure SQL Database Provisioning and Shortcuts Configuration. You can now apply consistent T-SQL formatting across your projects, create free tier cloud databases with automated post-deployment actions, and streamline frequently used commands and queries directly inside Visual Studio Code. What's new in MSSQL extension for VS Code v1.45 Here's a summary of t...
Aspire 13.5 refreshes the dashboard and aspire.dev, expands the Interaction Service, adds cross-scope Azure references and Kubernetes persistent volumes, and brings live terminals into the AppHost.
The WinApp VS Code extension exists to make Windows app development feel at home in VS Code. It brings the Windows App Development CLIright into the editor, so you can initialize, run, debug, define the identity of, package, and sign Windows apps built with .NET, WPF, WinUI, C++, Electron, Rust, Tauri, or Flutter, all without switching tools. Get it now: Install the WinApp extension from the VS Code Marketplace. We're excited to announce the release of v0.3.0. This release brings schema-aware IntelliSense to your manifest files, adds workspace search to the commands that require a file or folder, and i...
Anthropic's 2026 Agentic Coding Trends Report captures an important tension in how developers use AI. Engineers report using AI in roughly 60% of their work, yet say they can fully delegate only 020% of their tasks. AI is becoming a constant collaborator, but it still needs setup, supervision, validation, and human judgment. That gap is especially relevant when an agent starts working with a database. Database requests often sound easy. Show me the failed orders from last week. Why is this query expensive? Does this container have the field I need? For a developer, answering those question...
Hybrid search is usually described as combining keyword search with vector search. Microsoft SQL does that, for sure, but we do quite a bit more right out of the box. SQL dynamically evaluates queries and switches between kNN and ANN vector search based on cost and selectivity. These two types of hybrid search, work together, ensuring your semantic queries return the best possible results to your apps and agents. Text search In 1998, Microsoft Research Cambridge welcomed Stephen Robertson, one of the principal architects of BM25, or Best Matching 25, the relevance-ranking algorithm that became foundational to m...
What's a PFN? MSIX introduced Package identity in Windows 8. While the familiar package identity "5-tuple" was functional, it wasn't especially convenient to pass through APIs or embed in resources such as files, registry keys, URLs, or XML documents. To address this, Windows defined an opaque string representation known as a Package Moniker. Windows called a related identifier derived from a package's Name and Publisher the Package Family Moniker. These were commonly abbreviated as PM and PFM. As development progressed, Windows quite sensibly required new APIs to pass through API Design Review. The review tea...
A contingency plan.
Apple developers can now build and test their applications natively on Apple Silicon in Azure Pipelines. New arm64 macOS agents are available in public preview through the pay-as-you-go GitHub-hosted Agents pool. Starting with Apple Silicon, Azure Pipelines is bringing over some of the agent sizes already available in GitHub Actions. The preview includes the following macOS images: Running workloads directly on Apple Silicon avoids the overhead and compatibility limitations of emulating arm64 on Intel hardware. It also lets teams validate applications against the same architecture used by current Apple device...
Structured outputs, web search, web fetch, MCP connector, and tool search are now available for Claude models hosted on Azure in Microsoft Foundry, turning a model endpoint into a production agent platform.

Windows App Development CLI v0.6.0 has just shipped and contains a ton of new features. Much of the changes in this release focus on getting from zero to a running app faster: scaffold a fresh WinUI project with a single command, search real WinUI controls and samples without leaving the terminal, and run your app straight from a .csproj with no manual build step first. It also adds cloud-based artifact signing, sparse-package workflows, and agent-friendly UI recordings. Grab it with winget install Microsoft.WinAppCLI, or head to the repo for npm and other install options. Here's a tour of the highligh...

Agentic Platform Engineering for SaaS. Accelerating the Path to Market with Git-APE If you are an ISV building SaaS on Azure, the first demo is usually the easy part. The harder work is turning that proof of concept into a secure, scalable, commercial-ready service that can be operated confidently in production. That gap shows up quickly. Tenant isolation, identity, entitlement, marketplace fulfilment, metering, cost controls, observability, compliance evidence, and a clean path from customer purchase to tenant provisioning all need to be designed in, not bolted on later. None of those are side quests....
A new release of the Microsoft build of Go including security fixes is now available for download.
We know that slow builds are a consistent theme in feedback from C++ developers. Your feedback helped us to shape GitHub Copilot build performance for Windows, an agent that can trace your build, find bottlenecks, apply optimizations, and measure the result. When using the agent, the clearest outcome is a straightforward win. The agent changes your project, rebuilds it, and shows how your build is made faster. Sometimes, a change may make a clean rebuild slightly slower while improving the incremental builds you run throughout the day. At other times, we also observed that optimizations may help without reachi...

BlockOnPossibleDataLoss can frustrate developers, but it's one of the most important safeguards in database deployment. Here's how to keep your local development loop fast while protecting the data that matters.
LPPROC_THREAD_ATTRIBUTE_LISTs
Another RAII-style wrapper.
Most of us are familiar with one-to-one agent chats: private, direct interactions where rules are relatively simple. With only you and the agent, each moment has clear intent. You can ask follow-up questions, pause, or restart without worrying about how each exchange affects anyone else. Collaboration in groups works differently. Every message competes for attention, and a reply that is helpful to one individual may interrupt five others. Effective collaboration is built on countless small social judgments and gestures: deciding when to respond or stay quiet, choosing how much to say, and using the conventions...
Enterprise content is no longer just something people read. AI apps and agents are only as useful as the information they can understand, yet much of the worlds enterprise knowledge is locked in documents, forms, tables, images, audio, and video. The latest Azure Content Understanding updates help developers turn that content into structured, grounded data with less custom processing. This release brings broader support for the GPT-5 model series, lower token usage, improved confidence scoring, new synchronous APIs for Read and Layout, advanced contextualization for higher-quality extraction, new tax-focused pre...
Enterprise content is no longer just something people consume. As organizations increasingly rely on AI to extract and act on information from documents, images, audio, and video, Azure Content Understanding is expanding support for the GPT-5 series and improving grounding and confidence to deliver greater flexibility, efficiency, and quality. This expanded model catalog enables organizations to choose the right level of intelligence for each workload, helping reduce costs for high-volume processing while preserving access to advanced reasoning capabilities where needed. It also provides optimized pipelines tu...

These updates include major SBOM improvements in vcpkg-tool, 302 updated ports including multiple major library upgrades, and other minor improvements and bug fixes.
What parts of building and shipping on Azure still take too many steps? Maybe you want a command that starts a project with your organizations approved architecture and infrastructure. Maybe you need to connect deployments to an internal service catalog, run security checks before provisioning, or guide developers through a process that currently lives across scripts and documentation. When we first introduced the azd extension framework, we invited developers to think about that wish list. The framework was still taking shape in beta, and we wanted to learn which workflows developers and platform teams ne...

A recap of the latest servicing updates for .NET and .NET Framework for August 2026.
If you've worked with Git submodules for any length of time, you probably have a love-hate relationship with them. They're genuinely useful for pulling a shared library, an SDK, or common build scripts into your project. But actually working with them usually means tabbing over to a terminal and trying to remember whether it's this time all while a perfectly good IDE sits right in front of you, shrugging. That's the part we wanted to fix. Starting in Visual Studio 18.9, Git submodules are a first-class part of the IDE no more bouncing out to the command line just to keep your dependencies in order. It's been one...
MSIX uses a Garbage Collection (GC) design for staged package lifetime and destaging. Throughout this article: Package Core Principles A staged package can't be destaged while any references to it exist. This is a direct consequence of MSIX's core architectural principles: Consequently, removing a package's payload from disk is not a direct result of a single API call. Instead, package payloads are automatically destaged when they are no longer needed. Even then, destaging may not occur immediately. Some actions that remove a reference don't directly trigger Deployment activity. In these cases,...
It had been there long before Windows 95, but nobody remembered.
As app developers, our primary focus is building great user experiences, designing APIs, and shipping features quickly. What we don't want is database frictionwasting hours configuring local DB instances, writing verbose migration scripts by hand, or worrying about unexpected cloud bills while prototyping. Today, we are making database development fast, intelligent, and completely free. By combining the Azure SQL Developer Container for local offline development, AI Agent Skills to automate your ORM and data layer, and the Azure SQL Database Free Tier, you can build locally and ship to production in minutes f...
We're back, and this is our first minor version bump: 0.1 to 0.2! It's our biggest release yet. This update adds support for local models, lets you run a different agent in each tab with , brings OpenCode into the built-in agent lineup, runs your agent inside WSL where your work actually lives, and makes the Agent Pane richer to navigate and easier to read. It also sharpens Autofix and fixes a long list of reliability issues. You can grab the update from the Microsoft Store, via , or by heading to the release page on GitHub. Let's dive in! Local model support is here! We've heard you: one of the most common ...
