I'm relatively familiar with .Net (been using it since late 2001), that said, it's changed dramatically, more so in the past 3 years than nearly a decade before that. The changes between Framework 4.x to Core 1, 2, 3 have been somewhat dramatic and painful trying to keep one application current (that needed portability, including rpi). Hopefully the move to .Net 5 will be less painful. I'm mostly playing devils advocate as it's not been a smooth transition and the best way to do many things has changed since some things are in the box, that didn't used to be, but still rough around some edges. Many libraries and patters for web api projects are a bit different, better but different.
