If you download the "classical" Visual Studio installer from https://www.visualstudio.com/en-us/downloads/visual-studio-next-downloads-vs.aspx it allows you to install F# into VS.
Since it's not selected by default, a lot of our users will forget about it.

Since Visual Studio 2015 we have "on demand" installation of F# when you open a fsproj. This is still working with the latest installer, but opening a fsx file is still not triggering "on demand" install.
This is seriously hurting FAKE users. Before VS 2015 changed that install model FAKE always worked out of the box for all VS users (most FAKE users are C# devs).
