Others have listed some useful stats and market share info so I will stick to my experience. Currently working at a company that offers online pre employment testing. We integrate with a lot of applicant tracking systems. Our entire backend is written in dotnetcore. A lot of our partners are also using dotnetcore. There is no way I would classify it as a dead-end job. It definitely is not used as much at the big FAANG but there are plenty of small to medium size companies that rely on the MS dev stack.
