[Marian Luparu @mluparu]

I’m starting something new. To kick things off, I wrote a short post on a completely uncontroversial take on AI: in 2026, nobody is building for chat anymore https://t.co/I8Y8Hp9lyv

[vcpkg @vcpkg_io]

vcpkg now has 2,824 ports. May's release brought Boost 1.91, Qt 6.11, and OpenCASCADE 8.0 updates, plus 27 new ports and 521 total port updates: https://t.co/hTjw5TPhF7

C++ folks, rejoice 🎉
PackageReference is now in VS for C++ — cleaner deps, faster restores, zero clutter.
MSBuild-native + NuGet harmony = happy builds 😎

[Niklas Lundberg @datgame]

@visualc But still requires the Child Process Debugging extension to be separately installed and enabled.
Why not have it as a core feature?

[Visual C++ @visualc]

MSVC now supports Sample Profile Guided Optimization (SPGO). Collect hardware performance counter samples from your actual release binaries in production, then feed them back to the compiler for PGO-quality optimizations. No instrumented builds needed.

Native C++ projects in Visual Studio now support PackageReference. Declare NuGet dependencies directly in your .vcxproj, get transitive resolution, and use the global package cache. This feature is experimental in the Insiders Channel. https://t.co/d8Ae5YJNhJ

[Python Visual Studio Code @pythonvscode]

We’re at #PyCon2026 in Long Beach, CA (May 14-17)! 🐍
Stop by the @Microsoft + @GitHub booth for 10-min hands-on labs with GitHub Copilot, Azure AI Search, and more.
Also: catch a sneak peek of Pylance + Pyrefly integration at the Meta booth Saturday at 1pm.
See you there 👋

🪄 Your agent experience, refined.

The latest @code release brings better BYOK visibility and control, integrated browser improvements, and more.

It also introduces the new Agents window (preview), making it easier to explore, iterate on, and review tasks across multiple projects.

MSVC Build Tools v14.51 is now GA and the default in VS 2026 v18.6. Additional C++23 support, codegen improvements that speed up your binaries without touching source, and preview support for Intel APX.

Yup, platform activity is surging. There were 1 billion commits in 2025. Now, it's 275 million per week, on pace for 14 billion this year if growth remains linear (spoiler: it won't.)

GitHub Actions has grown from 500M minutes/week in 2023 to 1B minutes/week in 2025, and now 2.1B minutes so far this week.

So we're pushing incredibly hard on more CPUs, scaling services, and strengthening GitHub’s core features.

And as a fine purveyor of hand-crafted shit code for many years, I'm not gonna weigh in on that. 🤣

[Visual Studio @VisualStudio]

MSVC Build Tools 14.51 RC is here: C++23/C++20 conformance fixes, modernized parser, consteval + coroutine improvements, tons of SSA/CSE/SROA/PGO optimizer wins, preview Intel APX, full ARM64 SVE, SIMD‑boosted STL, and a long list of bug fixes.

How can we make the unit testing experience in Visual Studio significantly better?

C++ and .NET devs: What’s your biggest frustration with Test Explorer, test discovery speed, debugging, Live Unit Testing, Google Test integration, or anything else?

VS Debugger Agent now runs a guided, runtime‑aware loop: analyzes the issue, sets smart breakpoints, watches your repro live, validates its hypothesis, and applies the fix when you approve. Less guessing, more verified fixes.

MSVC Build Tools 14.51 is stacking real C++23 gains: easier constexpr, smarter Unicode, new <flat_map>/<flat_set>, a long‑awaited <regex> overhaul, plus SIMD‑powered STL algorithms.

The 2026 ISO C++ developer survey is open — takes ~10 minutes and directly informs the standardization committee and tooling vendors. Please share your feedback and share with your colleagues!

GitHub Copilot Build Performance helps reduce C++ build times by identifying expensive header includes, template instantiations, and function generation costs.
It then plans optimizations, with you in control.

[Marian Luparu @mluparu]

"Why are you taking things out of context?". In the world of AI agents, that's actually the right question. Context rot is a silent killer of autonomy.

The next season of agents won't be defined by context size, but by how effectively agents can forget

MSVC Build Tools version 14.51 brings a big batch of C++23 features: flat_map, flat_set, portable assumptions, relaxed constexpr, and more. Only 2 features left for full C++23 support: https://t.co/WYHjFJNRRW

vcpkg updates are in: parallel installs, smoother downloads, a Windows OpenSSL fix, and a mountain of port updates — all validated across the main triplets.
