Transform your legacy C++ applications with confidence. Whether you're upgrading from Visual Studio 2008 or modernizing to take advantage of the latest C++ features, this comprehensive guide provides everything you need for a successful upgrade journey.
đ Quick start
Most projects upgrade seamlessly: For projects created in Visual Studio 2010-2017, simply open them in the latest Visual Studio. For Visual Studio 2008 or earlier projects, use our two-step upgrade process.
Binary compatibility: Visual Studio 2015, 2017, 2019, 2022, and 2026 build tools are binary-compatible, so you can upgrade without rebuilding library dependencies. Learn more.
CMake projects: For projects using open-source libraries or targeting multiple platforms, consider migrating to CMake. Learn more.
