I have the following Individual Components installed to get the command line compiler working. This appears to be the minimum set of components required to get the Visual Studio Build Tools to work. ``` Code Tools Text Template Transformation Compilers, Build Tools, and Runtimes C++ 2019 Redistributable Update MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.28) MSVC v142 - VS 2019 C++ x64/x86 Spectre-mitigated libs (v14.28) Debuging and Testing C++ Build Tools core features C++ core features Development activities C++ Build Tools core features C++ core features SDKs Libraries and Frameworks Windows 10 SDK (10.0.19041.0) Windows Universal Runtime ``` Some are forced on by the installer itself, the spectre-mitigated libs I added manually. NB: .NET support removed saving about 1 GB of space NBB: works for pure C/C++ including SQLite3 and Python
