I am using Fira Code with Visual Studio (2015 Update 3) and the ligatures are there! I don't know if that's new, I recall that this used to not be the case?
Anyway, the instructions (once the font is installed on the Windows system):
Tools (menu) --> Options (menu item) --> Environment --> Fonts and Colors --> Show settings for: Text editor (pull-down). Font pull-down is directly below that.

VS is on supported list already, thanks for confirming
@tonsky Hi, I should have been more specific, I don't see it here: https://github.com/tonsky/FiraCode/wiki
(VS Code is a different product.)
That鈥檚 intentional 鈥斅爐here鈥檚 nothing special required to enable ligatures except just selecting the font. I鈥檝e added a paragraph about that to the wiki
Ignore this. After starting a new VS instance I see the ligatures and the font renders a bit more smoothly too.
Do the ligatures only work from a certain update of VS2015? I am still using Update 1, just heard about and tried Fira Code and am not seeing the ligatures.
I'm using VS 2017, I've selected FiraCode in settings and I don't see all the ligatures that are available (I've restarted VS)
For example |> changed into triangle, but -> is the same instead of changing into arrow.
Do you know what's wrong?
Not all editors show all the ligatures. Sometimes internally editor split ligature into different tokes because of how its syntax parser is written. Try testing the same ligature in plain text file or inside a comment
In case it helps someone: on VS 2017, when you select the font you can see that it changed, but the ligatures won't work until it's restarted.
