I want to add an existing folder to my F#.NET project in Visual Studio Ultimate 2013.
Some Stackoverflow-related issues relate to this issue, most of which mention the mythical "Show all files" icon as a protection at the top of Solution Explorer.
However, I do not have such an icon, and I cannot conjure it. Regardless of whether I click on my solution or my project, the upper part of Solution Explorer remains the same, both do not have "Show All Files":

I tried to implement the Rodolfo Maayos solution to no avail - I still get the above top section of the Solution Explorer.
Dragging and dropping folders will not work, as well as any other tricks from Stackoverflow or the network, or the ones I tried to come up with ...
Adding a folder to a project is truly the pinnacle of programming know-how, so I fully understand why Microsoft made it so complicated in Visual Studio Ultimate 2013.
visual-studio-2013 folder f # add project
