I have very narrow experience as I've only worked in financial services but your standard commercial bank is heavily invested in the Microsoft stack, specifically C# + SQL Server since we're so dependent on Excel and Outlook. Type C# in glassdoor and you'll be amazed by the diversity of open positions. After speaking with some friends, it appears that most non-software companies depend heavily on the MS stack as well.
I'd say that if you want to cast a wide net in the job market, Microsoft products are still a great thing to have on your resume.
