Microsoft's official open-source implementation of the C++ Standard Library (STL) that ships with the MSVC toolset and Visual Studio. The repository hosts the source code, CMake build system, and test suites for contributors and those porting the library elsewhere.
Use cases
- contribute fixes or features to MSVC's C++ standard library
- report bugs in the STL shipped with Visual Studio
- track which standard library changes appear in each VS release
- reuse the STL implementation in other compilers or tools
- port the C++ standard library to new targets
When to choose
- you want to contribute to or file issues against MSVC's STL
- you need the standard library source for another toolchain
- you want to follow C++ standard library conformance work
When to avoid
- you just want to use the STL in your C++ programs - install Visual Studio instead
- you need a standard library for GCC or Clang on Linux/macOS
