title: Visual studio , Build tools needed to be installed or not
body: <p>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)</p>
