I want to view different parts of the same C # code file in two separate columns side by side (horizontal separation of the editor). I can put the editor in two column mode, but I cannot find a way to view the file at the same time in both columns.
The related solutions that I found by searching seem to be for previous versions of Visual Studio. They refer to menu options, such as Window -> New Window, which are missing for me in VS 2017.
Is there no way to view different parts of the same file in two columns in Visual Studio 2017?
