The ecosystem is really it, C# as a language isn’t the best, objectively Typescript is a much more developer friendly and globally type safe (at design time) language. It’s far more versatile than C# in that regard, to the point where there is almost no comparison.

But holy hell the .Net ecosystem is light-years ahead, it’s so incredibly consistent across major versions, is extremely high quality, has consistent and well considered design advancements, and is absolutely bloody fast. Tie that in with first party frameworks that cover most of all major needs, and it all works together so smoothly, at least for web dev.

Pretty much.

For instance focusing on PR size. PR size may be a side effect of the maturity of the product, the type of work being performed, the complexity or lack thereof of the real world space their problems touch, and in the methodologies habits and practices of the team.

Just looking at PR size or really any other single dimensional KPI lead you to lose the nuance that was driving the productivity in the first place.

Honestly in my experience high productivity comes from a high level of unity in how the team thinks, approaches problems, and how diligent they are about their decisions. And isn’t necessarily something that’s strictly learned, it can be about getting the right people together.
