MSVC Address Sanitizer updates in Visual Studio 2022 version 17.13
We have been investing in the quality of MSVC Address Sanitizer (ASan) in several key areas over the past year, including working with LLVM upstream to stay coordinated with their changes, adding coverage for internal tools and libraries, and hardening APIs and runtime modes. Upstreaming to LLVM MSVC ASan is derived from a fork of the LLVM repository. Prior to Visual Studio 2022 version 17.12, MSVC ASan was based on outdated versions of LLVM’s compiler-rt (where the ASan source code lives), and we could not incorporate changes from newer versions of LLVM without significant delay.  We have recently comple...

Document build instructions and more with enhanced C++ awareness from Copilot Chat in Visual Studio
C++ development often involves nuances beyond the file you’re developing in. This can leave developers with many mental tabs open, balancing all the relevant context for their project to develop their C++ code properly. Copilot Chat in Visual Studio can already utilize context provided by specified files and invoked agents such as @workspace to generate suggestions. However, to improve the relevance of Copilot suggestions, we must provide tailored context to Copilot with considerations specific to the C++ language for developers to achieve better results. That way, developers can focus less on providing all th...

MSVC Compiler Language Updates in Visual Studio 2022 version 17.12
Introduction In alignment with the Visual Studio 2022 version 17.12 release, and based upon feedback received from the community, the MSVC compiler team would like to provide greater visibility into the C++ language-level fixes for customer-reported issues that made it into the release. This is similar to how the standard library team publishes regular changelogs (see VS 2022 17.12 for reference). The focus for Visual Studio 2022 version 17.12 is primarily to address bugs reported through Developer Community. C++23 Features: While our overall focus has been on fixing bugs reported via Developer Community, we i...
