I’m afraid that was all I knew 
I’m beginner at this and struggled to find a solution that worked for me. Wanted just to build the game see how it works.
The visual studio part was just for me to study the code as I’ve found out that the blueprints inside unreal derives from c++ classes. I’m more of a blueprint guy, my knowledge of visual studio or the EOS part from unreal are limited.
Once I’ve figured out how to make it work I’ve posted here.
About the build. Once you have also created the visual studio project, just leave it be and build from unreal. just to see if it works. just use the build package options from the editor. Not from visual studio. It should build the single player game.
So don’t use visual studio to build, but the unreal editor itself. You don’t even need to open visual studio if I recall.
How to build the various options, i’m afraid I don’t know, I didn’t study that part. I think the answer is in finding a tutorial from unreal that shows how the EOS works and how it integrates with a project.
If you figure that part out please post here
EDIT: I’ve build the game both for blueprint and C++ using the unreal editor, the normal way of building a game. Just give it a folder where to save and should build the game directly. no changes required to the project.
