Every major first party product has been using their own siloed UI framework since like 2003-ish. Visual Studio has always been one of the worst offenders. Sometimes the new UI components in a VS became the new normal for the rest of the first party stuff, but it was usually right about the time a new VS came out with a new paradigm. That's slowed a bit with the last bunch of VS releases being basically the same UI with different toolchains and default plugins, but it's still quite different from the rest of the OS. It's really pretty silly.
