It is crazy slow. I went ahead and turned off VS_GLOBAL_RunCodeAnalysis in my project. I also left VS_GLOBAL_EnableMicrosoftCodeAnalysis off, so clang tidy only. I’ll just run it once in a while manually. With the rest of the settings, “Analyze->Run code Analysis” runs clang-tidy manually. Once I have continuous integration going on this project, I’ll set it up to run there too. But too slow to run on a normal local build.
