How to upgrade from VS 2017 to 2019?
We cannot directly upgrade VS 2017 to VS 2019. They are compatible and work side by side though (like the following). Please download and install VS 2019 from https://docs.microsoft.com/en-us/visualstudio/releases/2019/release-notes
On Visual Studio Installer, You will see two tabs : Installed and Available. On Installed Tab, Visual Studio Community 2017, Click on More Drop-down, Choose Uninstall. Reboot is recommended before you begin with Installing Visual Studio Community 2019 from Available Tab.
