Visual Studio 2017 RTM release includes the C++ Core Guidelines Checkers as part of Code Analysis tools for C/C++. We have gotten a ton of useful feedback on the early previews of these checks through our external customers. Thank you for engaging with us and giving us great feedback. This feedback helped us improve the quality of the final released version of C++ Core Guidelines checks. Some of these improvements are explained in detail in this blog post about
Besides shipping the C++ Core Guidelines checker, we also fixed more than 150 bugs in our core analysis engine. All of these fixes are available in the Visual Studio 2017 RTM. As a result, developers should expect to see accuracy improvements in C++ code analysis. Download Visual Studio 2017 today and let us know what you think of the improvements to code analysis!
