I feel like OP might be in the situation where he's just skipping a huge amount of BS. A lot of shiny flashy stuff bring built today is basically unmaintainable garbage wrapped in gold colored tinfoil. You bring up C#. Microsoft is doing a big push towards a unified cross platform set of tools based around C#. Might make sense for OP to learn than because it's just a one step from what he's using now. Best code is being able to use netcore alongside the older tech and it interops fine. That said I'm out of my element here.
