April 13, 2026 - New MSBuild and CMake C++ projects now use Segment Heap by default, helping applications take advantage of modern Windows memory management and security features. Visual Studio now enables Segment Heap by default for new C++ projects. Segment Heap is a modern Windows heap implementation that improves performance, scalability, and security compared to the legacy NT heap.

r/cpp_questions on Reddit: C++23 in CMake on Visual Studio 2026
March 24, 2026 -
This post has been uploaded to r/VisualStudio as well.
Hi, I'm relatively new to programming in general, sorry if this is dumb but I can't find an answer and AI is hopeless. I am using a book to learn C++ (Beginning C++23: From Beginner to Pro 7th Edition), so I want to use the latest C++23. I have Visual Studio 2026, and under modify in the installer everything is selected and it is updated. If you want I can tell you what I have already tried with AI, but, it hasn't really worked (it seemed to output the right thing but underline C++23 things as wrong, and when I removed "import std;" it still ran, I have no clue why) so it probably is just the wrong thing and wouldn't help. Thanks in advance!

Sorry I realise this is probably not the right sub-reddit, and this is more the actual language, not an IDE. Sorry! If somebody could help it would still be greatly appreciated!

r/cpp on Reddit: VS 2026 18.0 / MSVC Build Tools 14.50 released for production use
November 11, 2025 -
See the VS 2026 release notes for everything that's changed in the product, the MSVC compiler team's blog post about C++23 Core Language features (yes, they're finally working on C++23!), and as always, the STL Changelog's detailed summary of everything we merged for this release. I take great care to record every single commit that goes into the STL, excluding only README updates and utterly trivial or internal-only changes.
If you have questions or concerns about the product, I can typically get MSVC team members to respond directly here (and I can answer STL questions myself).
Edit: Shortly after I posted this, we also published What's New for C++ Developers in Visual Studio 2026 version 18.0 which covers C++-specific IDE features (and some overlapping mentions of compiler and library changes).

One question, and I am not joking or trolling, and this is coming from someone who has used every Visual Studio version going back to Visual C++ 4.2 (well, except for VS 2013). Can I fully disable CoPilot / AI? (anything beyond visual assist/resharper features. I don't use GitHub.

Nice! I'd have preferred an abi break at this point in time but that's the way it is

How Visual Studio 2026 Quietly Stole My vcpkg | by Allen Kuo (kwyshell) | Medium
April 12, 2026 - By the time CMake reads your CMakePresets.json, the environment is already version-locked. Here’s the thing: VS 2026’s IDE injects VS 2026 paths. That’s perfectly sensible — you’re inside VS 2026, why would it inject anything else? But for a power user trying to pin vcpkg back to VS 2022, it’s a brick wall. The environment variables I can control — VCPKG_VISUAL_STUDIO_PATH and VCPKG_PLATFORM_TOOLSET — only affect which cl.exe vcpkg picks for its internal package builds.
