Stephan T. Lavavej - MSFTJuly 2, 2020Jul 2, 202007/2/20

What's New We've been busy implementing C++20 features in MSVC's compiler and Standard Library, and migrating the latter to microsoft/STL on GitHub - in fact, we've been so busy that we haven't posted a C++ toolset changelog since the VS 2019 16.0 toolset changelog. So, here are the compiler features and STL features/fixes that have shipped

Linux development with Visual Studio: first-class support for gdbserver, improved build times with Ninja, and updates to the Connection Manager

ErikaJune 2, 2020Jun 2, 202006/2/20

With Visual Studio 2019 you can build and debug C++ projects on a remote Linux system or the Windows Subsystem for Linux (WSL). You can get started with Linux development in Visual Studio using MSBuild-based Linux projects or our native support for CMake. CMake lets you use the same source code and build scripts to target multiple platforms an

Profiling template metaprograms with C++ Build Insights

Kevin CadieuxMay 28, 2020May 28, 202005/28/20

The use of templates in C++ programs can sometimes lead to longer builds. C++ Build Insights puts tools at your disposal for analyzing template usage patterns and their associated impact on build time. In this article, we show you how to use the vcperf analysis tool and the C++ Build Insights SDK to understand and fix problematic template patt

Faster builds with PCH suggestions from C++ Build Insights

Kevin CadieuxMay 8, 2020May 8, 202005/8/20

The creation of a precompiled header (PCH) is a proven strategy for improving build times. A PCH eliminates the need to repeatedly parse a frequently included header by processing it only once at the beginning of a build. The selection of headers to precompile has traditionally been viewed as a guessing game, but not anymore! In this article,
