If you have done all of the above and still isn't working , just try this: Note: you should have updated VS.

Goto Unity > edit> preference >External tools> external script editor. Somehow for me I had not selected "visual studio" for external script editor and it was not working. As soon as i selected this and doubled clicked on c# file from unity it started working.

I hope it helps you too.
