I\'m trying to create a setup project / installer for a C# project but can\'t find the \'setup project\' template in VS2017.
In VS2015 it was under: Other Project Types
You need to install the "Microsoft Visual Studio 2017 Installer Projects". Open up MSVS Tools->Extensions and Updates (Extensions and Updates popup form appears) Online->Visual Studio Marketplace->Tools->Setup & Deployment. Then select "Microsoft Visual Studio 2017 Installer Projects" (today, August 20, 2018, the version is 0.8.8).
NOTES: These are more of the classical MS installers we all know and love used since VS6 days.
