I am wondering for a long time As I am working with visual studio 2019 and I have all of the tools in my Visual studio 2019 installation , so do I need to update build tools which comes separately in vs installer, do we even need these build tools installation ,for our work environment , I don't think I have even used these, ( may sound a dumb question but I am curious)
No, you don't need them. However, I install them as well because it enables me to develop and test the build scripts on my machine which will run then on build servers which have the Visual Studio Build Tools installed only.
