In case you are interested, Urban Linker (french recruitment agency) publish somewhat detailed salary stats (in French), last one is form 2016 [0]. This only covers Parisian region, but it's really interesting to see how technology affect the salary.
This actually lines up with what I, a mid level .Net dev was expecting. When I first arrived in Paris I thought the compensation was low, but I was educated that that was the standard. It's improved a bit but not a whole lot.
Paris is still a great city to live in. We even managed to live there with child.
