Resources for the SQL AI Developer
I see three agentic stories shaping SQL’s future. Here’s how DP-800 connects the pieces and helps you build the skills to put SQL’s AI capabilities to work.
Preconfigured agents with Microsoft Agent Framework for Go
Use harness.AgentConfig to configure task lists, file memory, skills, approvals, conversation history, and tracing for agents written in Go.
Content Understanding adds GPT-5.6, GPT-6, and GPT-6.1: Choose the right model for your workload
Azure Content Understanding now supports the GPT-5.6, GPT-6, and GPT-6.1 model families, giving you more choices for document, text, speech, and video workflows. This adds to the existing set of supported models like the GPT-5 series. To help customers understand how to use this expanded set of options, we're updating our model recommendations and sharing the evaluation data behind them. In our GPT-5 model-selection guide, we described model selection as a mixing board: adjust quality and cost for each workload. The new models add range to those controls. Not every workload needs to be set to maximum, so w...
Bring Your Own Model is now generally available in Visual Studio
Whether your team hosts its own AI models, you have an API key from a model provider, or you want to experiment with a model running on your machine, Bring Your Own Model (BYOM) lets you use those models without leaving Visual Studio. BYOM is now generally available in Visual Studio 18.12. Since the August Preview, your feedback has shaped improvements for team deployments, enterprise networks, and personal projects. This release brings multiple configurations for the same provider, a dedicated custom-endpoint experience that includes local models, more control over API compatibility, and improved proxy suppor...
I didn’t write a program with emoji, but I did use a control character

What’s new across Microsoft SQL in 2026 so far: the PASS Summit West roundup
[almost] A year of building on Microsoft SQL - 2026 I'm back with a really long and exhaustive list of updates across Microsoft SQL in 2026. This time I'm tuning in from PASS Summit West, and I actually did this blog as a session with other members from the Microsoft SQL team. I'll put a link to that here once it's live. At PASS Summit West, it's a good time to take stock of what changed this year. From SQLCon/FabCon in Atlanta to Microsoft Build and SQLCon/FabCon Europe in Barcelona, the SQL team has shipped updates across SQL Server, Azure SQL, SQL database in Microsoft Fabric, and the tools you use every...
Automatic MSBuild configuration for the Microsoft C++ Language Server in Copilot CLI
Accurate C++ code intelligence starts with understanding how your project builds. Compiler options, include paths, and preprocessor definitions all affect how the language server interprets your source files. A compilation database, such as , provides that context, so that tools such as go-to-definition and find-references can resolve symbols accurately. The Microsoft C++ Language Server now brings automatic configuration for MSBuild-based projects to GitHub Copilot CLI, using the same enterprise-grade C++ and MSBuild tooling we’ve developed and refined over years of investment in Visual Studio. This extends ...

This post announces the General Availability (GA) of PowerShell 7.7, the next Standard Term Support (STS) release.
Announcing Visual Studio 2026 LTSC 18.11
Today, we are announcing Visual Studio 2026 Long-Term Servicing Channel (LTSC) 18.11 alongside Visual Studio 2026 18.12 on the Stable channel. LTSC 18.11 will receive two years of support, through November 14, 2028, rather than the one year of LTSC support we previously announced. If you are using Visual Studio 2022 for its LTSC benefits this is a great time to consider migrating to the new Visual Studio 2026 LTSC 18.11 to get the latest Visual Studio has to offer. Visual Studio 2026 LTSC 18.11 is not a new product - it is a new support and servicing channel for Visual Studio 2026 so it includes the full fea...

Activation via AppUserModelId
An application can be directly activated by calling IApplicationActivationManager::ActivateApplication() with its Application User Model ID, also known as AppUserModelId or AUMID. For example, let's use a package with this fragment: This package's full name is . The suffix is the publisher ID derived from the package's publisher. Its package family name is therefore . The 's attribute is the application's Package Relative Application Id, also known as PRAID. An AUMID is a combination of the application's package family name and PRAID: Thus the card reader's AUMID is . We can now activate the applica...

Copilot in Visual Studio Just Got a Major Upgrade
Copilot Chat in Visual Studio just got a new engine. Starting with Visual Studio 2026 version 18.12, it runs on the Microsoft Copilot SDK developed by GitHub, the same technology powering GitHub Copilot CLI, the GitHub Copilot app, and VS Code. It’s on by default, and it’s a major upgrade: same models, more tasks solved, new ways to work. We put the previous and new Copilot experiences through over one hundred coding tasks. The new experience came out ahead with every model we tested, across capability levels and providers, resolving up to 21 more tasks. The chat itself is better too: you get shorter, more ...

When one pass isn’t enough: agentic mode in Azure Content Understanding
Most document analysis takes one efficient pass. Learn how agentic mode gives AI a document-native harness for the hardest tasks, and when to choose it over standard mode. “Some books are to be tasted, others to be swallowed, and some few to be chewed and digested.” Francis Bacon, “Of Studies”, 1625 A.D. Francis Bacon once observed that an intelligent reader doesn’t consume every book the same way: some are swallowed whole, while a few must be chewed and digested. As we build specialized agents to process documents, we’re learning that lesson again. When we started building Azure Content Understanding in ...

Do AI coding agents care about SemVer?
We gave AI coding agents the same breaking upgrade twice. Labeled 2.0.0, Claude Sonnet 5.5 checked it in all 10 runs. Labeled 1.4.3, it checked in two and often left the app broken. Nearly 1,000 runs show which agents still read your version numbers, and what a patch label talks them out of.
If the Windows Update hot patcher checks that the function hasn’t already been patched, does that mean you can’t install two hot-patches?
It knows what it did.
How do you run a query against data the database can’t read?
Under the Hood: The Research Behind Microsoft SQL, part 3 Encryption at rest solves one threat. It stops someone who walks off with the disk. It does nothing about someone with administrative access to the running server, because the database decrypts data into memory to do anything useful with it. For a lot of workloads that gap doesn’t matter. For health records, financial data, or anything where the customer’s threat model includes the cloud operator, it matters a great deal. Azure SQL Database Always Encrypted (SIGMOD 2020) describes how SQL Server runs real queries, including range comparisons and L...

Why are we all worked up about atomicity when applying hot-patches if we can just suspend all the threads?
Suspending all the threads stops the threads that are there now, those are not the only possible sources of change.

Your best AX fixes are hiding in agent trajectories
All five agent runs produced a working script, and nothing in the eval score looked wrong. The trajectories told a different story. Every run read a DLL as raw bytes to find plugin names, and three scripts would quietly reroute a CI runner's network traffic. Here are the patterns to look for in your own agents' trajectories, and what to change in your product when you find them.
October 2026 Node.js vulnerabilities: Azure DevOps security guidance
On October 21, 2026, the Node.js project released fixes for 10 vulnerabilities. These include flaws in DNS resolution and TLS certificate validation, along with a Brotli decompression bug that can corrupt memory and potentially allow code execution when an application processes attacker-controlled data. The fixes shipped in 22.23.4, 24.22.1 and 26.12.1, with different affected branches and prerequisites for each CVE. Azure Pipelines can use Node.js in several contexts, including agent task runners, pipeline-selected tools and application runtimes. Each has a separate update path. Vulnerability scope...
