As a startup, what is it in for me to switch from Java, Spring Boot, Hibernate, Beam, Flink, Pulsar, Vault, KeyCloak ecosystem to C#.Net? Is the documentation better? Do I get better performance? Is the community larger and more stable?

Most of that ecosystem is language agnostic, or offer much more ergonomically sane APIs in dotnet. This is especially true for anything coming out of Google (e.g. Dataflow which runs on top of Apache Beam). C# itself has way better DX (object initializers alone are worth the switch), and most language features don't feel bolted on like with Java (anything from functional programming to extension methods to whatever).…

I sometimes miss Spring magic when working with ASP.NET, and I worked 12+ years with C# and only a year with Spring. Not saying one is better than the other, it's always a choice, less magic = more boilerplate and less boilerplate = more magic.

I HAVE FOUR WORDS FOR YOU: "I ... LOVE .. THIS .. COMPANY ... yeeeaaaahhhhhh1111"

Since Nadella took over, MS made some substantial steps forward: On Azure, around 30% is Linux; MS went cross platform with some of its most successful apps/ecosystems. Its not that MS behaving like a friend today, but their Dev-tools are really great - at least they care for Devs, i wish they would care for Office users as well.

C# + .NET is from my perspective the most developed and most mature eco system when it comes to business applications.

I really like it!

I really liked working with C#. I spent 15 years or so with it and found it very productive. But no; I don’t miss the culture of C# / Microsoft shops at all.

> culture of C# / Microsoft shops at al What do you mean?

Been awhile since I've worked at one but it is usually grounded in trying to achieve 100% MS usage.

It is rarish to find a partial MS shop. Most of this is how hard MS makes it to use other tools. Even in 2025 they have good interop with external tools hamstrung.

Example: SQL Servers JDBC driver will convert an entire table's of data from ASCII to UTF and a full table scan instead of convertering your UTF bind to ASCII and using the ASCII based index. This doesn't break interop but does make it painful to code and one more reason to just use .Net.

I've worked with .NET for over 10 years and we built our startup on top of it. Here are my thoughts: Pros: * Stability * Very decent standard library * Good balance between productivity and robustness * Great package management * Extremely easy to upgrade, so essentially free goodies (performance) every year or so Cons: * Very MSFT dominated (obviously) * Subpar tooling outside of Windows (I'm looking at you C# Dev K…

I've personally found Rider to be a great IDE for .NET development outside of Windows.

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.

As others have mentioned Vault, Keycloak, Flink are language agnostic. Regarding the switch from Java to .NET, I would rather recommend switching to Kotlin instead of .NET for a developer experience similar to C#, while still keeping your existing expertise in Java and its ecosystem. And this comes from someone in a .NET shop currently, but have worked with Java before. IMHO both languages and surrounding ecosystems are good. Both have their pros and cons and quirks.

> practically all Define “practically all”. I would accept “clear majority”. But practically all? Nah. I mean the hot new areas for funding right now are AI and robotics neither of which are web! I’m coming up on 20 years professional experience. Exactly none of it has been mobile or web! The programming field is so much bigger than HN likes to pretend.

The majority of software is probably Excel macros.

This probably isn't true but I want to read a super geeky dark sci-fi novel that explores this topic.

I worked at a Microsoft shop, and this was my experience. 1. Process, process, and more process. Doing anything required layers of management approval. Trivial tasks become month long, or even years long, processes. 2. You have no power or agency. Something is broken? You're a developer, you should be able to fix it right? No. Broken things stay broken. You swim in your lane and keep your head down. Mediocrity is the…

Those things have nothing to do with C# though, rather than your personal experience with companies that were using it.

If I judged every single company i worked at/interacted with, that uses NodeJs, I'd think that every single Node dev is a 13 year old child with no real experience but who think's he's the hottest shit. That has nothing to do with Node and doesn't really describe _all_ the companies out there.

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…

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

Not really, you should learn Typescript by learning JavaScript first. Then consider learning C#. Or if you want to focus on the back end side learn C# and skip TS/JS.

They are created by the same person but they are very different in my opinion.

TypeScript is "a tool" for JS, it is possible to compile without errors but still fail in runtime (e.g. wrong object type returned from API), on the other hand parsing JSON with C# will give you correct object type, it may fail if some properties are missing but it will fail at parsing call, not further down when you try to use missing property. In other words typing is not glued on top of the language it's core of the language.

I think the "confusing" aspect with C#, being part of the Microsoft eco-system, is that there are many smaller companies (and startups) that may have concern paying for such tools. To the uneducated, C# is linked to Visual Studio.. the IDE.. and the Community edition if free as long as you are a student, open-source, and individuals. Professional and Enterprise are paid. (Yes - there is Visual Studio Code) Again, I a…

> To the uneducated, C# is linked to Visual Studio.. the IDE..

Not native English - does "to the uneducated" means you are directing this sentence that knows no better or you are uneducated?

Because if it is former, you need to re-educate yourself.

C# is not linked to IDE. You can do `dotnet build`? Can run on Linux if you will. Database choice? You are NOT limited to SQL Server or Windows server.
