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...

Siemens Healthineers manages C++ libraries with vcpkg in an offline build environment
vcpkg is a free and open-source C/C++ package manager maintained by Microsoft and the C++ community that runs on Windows, macOS, and Linux. Over the years we have heard from companies using vcpkg to manage dependencies at enterprise-scale. For this blog post, I spoke to Shrey Chauhan, a Senior DevOps Engineer with Siemens Healthineers. Siemens Healthineers adopted vcpkg in late 2023 after a successful proof of concept. Their main motivation was to improve their versioning and overall dependency management for C++ libraries in their offline, air-gapped build environment. They also like vcpkg’s integration with ...

Enhanced Breakpoint Expressions for C++ Debugging in Visual Studio
Conditional Breakpoints Performance Improvement Debugging C++ code can be a time-consuming process, especially when dealing with complex scenarios. As a developer, it's frustrating to go through extensive setup and wait for a specific conditional breakpoint to trigger so you can analyze your application in a specific state. In Visual Studio 2022 version 17.10, we optimized the implementation of conditional breakpoints in C++ to enhance performance. We further improved this in version 17.11 to boost performance even more. Key Improvements Conditional breakpoints in Visual Studio for C++ pause code execution w...
