If you are using Vcpkg today with VS 2015 or VS 2017 for one or more of your open-source dependencies, you will be happy to learn that these libraries (close to 900 at the time of this writing) can now be compiled with the MSVC v142 toolset and are available for consumption in Visual Studio 2019 projects. Hundreds of C++ libraries on Vcpkg are available regardless of the toolset you’re using Specifically, the VCRedist can’t be older than any of the toolset versions used to build your app. When you mix binaries built with different supported versions of the MSVC toolset, there is a version requirement for the VCRedist that you redistribute with your app. C:\source\repos\TimerApp\Debug>dumpbin TimerApp2019.exe /IMPORTS | findstr. To make this possible, VC Runtime does not change its major version in VS 2019 and remains backward compatible with previous VC Runtime versions. This means that if you compile all your code with the v142 toolset but still have one or more libraries that are built with the v140 or v141 toolset, linking all of it together (with the latest linker) will work as expected. This is why we’re announcing today that our team is committed to provide binary compatibility for MSVC v142 with both MSVC v141 and v140. We want to keep the momentum going and make sure that you have a similarly successful adoption experience with MSVC v142 too. This allowed you to migrate your own code to the v141 toolset at your own pace, without having to wait for any of your 3rd party library dependencies to migrate first. We heard it loud and clear that a major reason contributing to MSVC v141’s fast adoption today is its binary compatibility with MSVC v140. VC Runtime in the latest MSVC v142 toolset is binary compatible with v140 and v141 The MSVC v142 toolset is now available and it already brings several incentives for you to migrate. Within the Visual Studio 2019 wave (previews, its general availability, and future updates), we plan to continue evolving our C++ compilers and libraries with And if you are starting fresh with only VS 2019 installed on your machine, it is very easy to acquire these older toolsets directly from the Visual Studio Installer by customizing the C++ Desktop workload (with the Individual Components tab listing all the options). Toolsets from older VS installations on your box are visible as platform toolsets in the latest IDE. This way, your projects also load in the previous version of the IDE in case you need to go back or you have teammates that have not yet upgraded to VS 2019 (this functionality is also known as project round-tripping). Loading your existing C++ projects into the IDE will not upgrade/change your project files. MSVC v140 (VS 2015.3) and MSVC v141 (VS 2017) Toolsets in the Visual Studio 2019 IDEĮven if you are not ready yet to move your project to the latest toolset (MSVC v142), you can still load your project in the Visual Studio 2019 IDE and continue to use your current older toolset. The Visual Studio Installer will let you manage installations of Visual Studio 20 from a central UI. This is a great way to try Visual Studio 2019 or adopt it for some of your projects. You can install the latest version of Visual Studio on a computer that already has an earlier version installed and continue to use both versions in parallel with no interference. Regardless of the toolset you’re on, you get access to the full collection of OSS libraries available in Vcpkg.You can upgrade to the latest MSVC v142 (VS 2019) and maintain binary compatibility with any of your 3rd party libraries that haven’t migrated yet.You can continue building your C++ code with the MSVC v140 (VS 2015.3) or v141 (VS 2017) toolsets. You can install the latest IDE side-by-side with any older VS versions.This post captures the reasons why your upgrade to Visual Studio 2019 will be pain-free. We hope that you will find these new capabilities compelling and start your upgrade to Visual Studio 2019 soon.Īs you are considering this upgrade, rest assured that Visual Studio 2019 makes it distinctively easy to move your codebase from previous versions of Visual Studio. Visual Studio 2019 pushes the boundaries of individual and team productivity.
