Microsoft Visual C 2019 2021

This paper examines the Microsoft Visual C++ (MSVC) compiler toolchain as part of Visual Studio 2019 (released 2019) and its major updates through 2021. It focuses on standards conformance (C++17/20), security enhancements, build throughput improvements, and the introduction of the /std:c++latest mode. The study finds that between 2019 and 2021, MSVC achieved near-full support for C++17, substantial C++20 feature completion, and significant parallel compilation optimizations, while maintaining backward compatibility with legacy code.
