I'm new and looking for advice.
A contractor came in and set up 2 duplicate sites, 1 for production & copy for development. They are on the same sharepoint 2016 on premise server.
One of the users has made changes in production site and not in the dev site. He has used only the SharePoint UI to do this. No programming.
Changes have to be made in programming so I'm thinking I need to copy the production site to staging. Make programming changes then upload staging to production.
There's 1 .sln file and 3 projects in visual studio 2017. In the project files are .cs files. I only want to modify some lines of code in the cs files. (Another couple of emails have to be sent when an event happens.)
But because the user has made changes in the production site - not sure if that affected the .cs files. There's only 1 set or programming files. The contractor set it up when both sites originally created.
I read where with Visual Studio you can create a .wsp file and import it into the server. But what I read says it applies to the whole site. Since I'm not sure if the SharePoint UI changes are part of the coding. Wondered if this was the way to go?
Any advice is appreciated. JS
