Visual Studio Pro created project folders

Um, really noob question, but should I add to workspace the solution folder or the project folder under it? Speaking of solution/project created in the visual studio professional.

The thing is, by default, VS is creating solution folder and first project folder with same name, and it seems to be problem for agents when they are reading files. But even when renaming the solution folder to something else, then the agent will try to run “dotnet run” in the solution folder which cannot find the project file in that folder. Then the agent might try change directory or might give up, depends.

So, what is really the best way to load and handle these VS pro created workspaces?

For example the folder structure might be:

C:\Git\App1\
 C:\Git\App1\App1.sln
 C:\Git\App1\App1\
  C:\Git\App1\App1\App1.cproj

And what happens if there are several projects in that one solution? Which quite often are either needed to build main project, or some times microservices etc., that are needed to be running same time.
