Why can't I see project settings in Visual Studio 2017?

Question

C++ / C#

I downloaded the project from the github for Visual Studio C ++ 2017. I open it, I look at the properties of the project, there are none of them.
How to see them?

Answer 1

open a window, let's say with main.cpp. Sometimes the visualizer shows the parameters of a freshly opened project, only the field of this procedure
