Any one that uses F# right now, can you tell me if you can create folders in Visual Studio? It seems like it's mentioned here, but I'd like a confirmation.
You can via the F# Power Tools; at least in VS2015. In VSCode just create the folder as per normal and hit "F1->F#: Add File to Project" using the Ionide plugin. Admittedly the need for folders in my experience is a lot less than in C#.
