Background - using 2017 Visual Studio I have created and tested multiple projects which now need to be consolidated into a single project. It should be simple, click the "Add Project", and select the folder. Nope, all that does is bore down into more folders under the project not allowing anything to be selected. So, how is this accomplished and more importantly is my philosophy correct? And where do you start, from the low projects and work towards the top? And as long as I'm being a pain, at some point I need to migrate from the studio to the executable - a good reference for this activity?
