.NET 10

For us, every .NET upgrade since .NET 5 has gone surprisingly smoothly and reduced CPU/RAM usage by 10–15%.

We were even able to downgrade our cloud servers to smaller instances, literally.

I wish .NET was more popular among startups, if only C# could get rid of the "enterpisey" stigma.

I'm at a series-C, YC startup. We made a switch from TypeScript to C# two months back. Now we have a team of over a dozen backend engineers working on C# transitioning from TypeScript. 90% are working with C# for the first time. (We are still hiring backend C# engs!)

I can say that it has gone waaaaaay smoother than anyone would have thought. This is a decision (language switch) that the team has been putting off for a long time and simply suffering through some big time jank and complexity with TypeScript (yes, TS at scale becomes complex in a very different way from C# because it becomes complex at the tooling layer in an "unbounded" way whereas C#'s language complexity is "bounded").

Indeed, I think more teams should give C# a shot. My own experience is that C# and TypeScript at a language level are remarkably alike[0] that if you know one well, you can probably quickly learn the other. But the C# ecosystem tooling is more cohesive, easier to grok, and less fickle compared to JS/TS (as is the case with Go, Java, etc. as well).

There still remains a lot of mis-perceptions about C# and .NET in general and I think that many startups should spend the time to give EF Core a shot and realize how every option in JS-land ends up feeling like a toy. EF Core itself is worth the price of admission, IMO.

So should I learn C# by learning Typescript? Does that make sense?
