What will do the Installation Folder URL will do while publishing the application?
I read so many articles got confused.
The "Installation Folder URL" in a Click-Once deployment is specific to deploying to a web server. If you're deploying to a file share you don't need to use it.
As an example, I published one of my Add-Ins to a GitHub repository.
Note: The setup.exe will use the "Installation Folder URL" as the install path.
