Cameron DaCamara
In this blog we will explore one change the MSVC compiler has implemented in an effort to improve the codegen quality of applications in debug mode. We will highlight what the change does, and how it could be extended for the future. If debug performance is something you care about for your C++ projects, then Visual Studio 2022 version 17.5 is...

Moving a project to C++ named Modules

Both warnings analyse standard containers for unchecked element access and they both share the warning ...

One small example of this in C++20 is conditionally trivial special member functions, which we added support for in Visual Studio 2019 version 16.8. Its benefit isn’t immediately obvious unless you’ve been deep down the rabbit hole...
