.NET gets selected because a lot of non tech companies need to do software things, and they pick the stack fits in with their current WinTel stack. The main concerns is having replaceable talent to reliably do x. They're not trying to innovate. They are often doing something like sending out insurance quotes by email. They do this by having strict processes, and having developers stay in their lane. Expect rigid scrum, using dependencies only supported by Microsoft etc, Locked down Dev machines with visual studio only, ask for microsoft dev certs, and expect pre-approved enterprise design patterns up the wazoo. They don't want innovative developers, they want you to fit into the pre existing framework designed by an architect. Your skills can die in such an environment.
There are companies that use .NET that aren't like this, but you have to go out your way to find them.
