"Granted this was a couple years ago and running dotnet framework, so perhaps things have improved" - I think this explains the differences in our opinions on .Net, as I'm from the opposite side of the spectrum having only worked on .Net Core on Linux. From other discussions I've had with people who used older versions of .Net, they seem to share your opinion that it was nowhere near as pleasant of an experience as something like .Net 5. As the other comment mentions, Span<T> has really permeated through core libraries, and the effect is much smoother, more predictable performance, with low memory usage making container based development a breeze.
