We are pleased to announce the availability of the release candidate for Microsoft C++ (MSVC) Build Tools version 14.52. With this release, C++23 is ready for production use and available through the /std:c++23 compiler option; see below for details. This is the last MSVC v14.52 preview before it moves to stable status and full support. The post MSVC Build Tools Version 14.52 Release Candidate Now Available appeared first on C++ Team Blog.

CMake Tools 1.24 includes several reliability fixes and productivity improvements. You can run tests from the editor, save preset-backed cache edits as user overrides, and keep source-file lists up to date. See the CMake Tools release page and full changelog for details. Thank you to the community contributors whose work is included in these updates: The post Visual Studio Code CMake Tools 1.24 appeared first on C++ Team Blog.

C++ repositories can contain millions of lines of code spread across deeply connected source files and headers. Without a reusable index, navigating to definitions, finding references, or searching for symbols may require portions of that information to be analyzed again as you move through the repository.

As we mentioned in the last cmath blog post, MSVC is using LLVM-libc for compile-time evaluation and runtime execution of math functions when /Zc:cmath is enabled. I invited LLVM-libc contributors Michael Jones and Tue Ly to write a guest blog post about how they’ve achieved what they’ve achieved. This is that blog post! I hope The post Bringing Correctly Rounded Math to Production with LLVM-libc appeared first on C++ Team Blog.

At CppCon 2026, we shared how Visual Studio is evolving to help you work more effectively with large C++ codebases, improve build and runtime performance, adopt the latest language features, and incorporate AI into your existing workflows.

Over the past few months, we have continued shipping monthly Visual Studio 2026 releases, delivering improvements across all stages of the development cycle. In this blog post, we’ll recap everything that changed from version 18.7 through 18.10 (released this month) that is relevant for C++ developers. This includes new tools for maintaining and navigating C++ The post What’s New for C++ Developers in Visual Studio 2026 (18.7 – 18.10) appeared first on C++ Team Blog.

Microsoft will be at CppCon 2026 in Aurora, Colorado, which is taking place from September 14 through 18. Join us for talks from Microsoft speakers and colleagues across the C++ community and visit the Microsoft booth Monday through Thursday to meet the team and discuss the tools, technologies, and challenges that matter to you.

Proposal P0533R9 made numerous math functions in the standard library compile-time evaluable in C++23. Implementing the feature required a good bit of time and effort, but MSVC is preparing its experimental implementation for the 14.52 build tools (compiler version 19.52)! We are still refining the feature, so expect the dust to settle only when this The post MSVC C++23: constexpr cmath with LLVM Libc appeared first on C++ Team Blog.

The MSVC Build Tools Preview is updated regularly with the latest features and fixes from the MSVC development team. This post covers updates from the past month, currently targeting the v14.52 release. This encompasses changes across the compiler frontend, backend, linker, standard library, and related tools.

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 The post Clearer Build Optimization Results with GitHub Copilot appeared first on C++ Team Blog.
