Discriminated Unions: Essa feature faz falta no CSharp
Inclusive, para suportar esse tipo de funcionalidade, foi criada a biblioteca OneOf: mcintyre321/OneOf: Easy to use F#-like ~discriminated~ unions for C# with exhaustive compile time matching (github.com)

Rolled my own Result<T,E> type that seems to work better than others.
Then I found discussion of the OneOf package, and then found some simpler Result code. I tried using that code but I found the use of Match and lambdas meant I couldn't simply break out of the loop in my example.

What's new in C# 12: overview
Until that feature lands there's this https://github.com/mcintyre321/OneOf which is pretty nice.

Exception handling between controller and service
Yep, it's called result pattern, aforementioned above. There was two highlighted implementations - OneOf, FluentResults.

Have you heard of AnyOf .NET Lib?
No he didn't. He made a video of the OneOf library. Not this one.

Have you heard of AnyOf C# Library?
We already have OneOf https://github.com/mcintyre321/OneOf I've used it in Production multiple times and it's an awesome way to keep everything strongly typed and eliminate null reference exceptions.

Is .NET just miles ahead or am I delusional?
Do these all compile to the exact same thing?

Yes, so you are right.

Generating C# code programmatically
Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

The One Billion Row Challenge – .NET Edition
One results in MOVSX, the other in MOVZX [1]. The difference thus is sign/zero extension when moving to the larger register. However, they seem to perform pretty much identical if I'm reading Agner Fog's instruction tables correctly.

C# Testing Playgrounds for old versions?
The closest online tool I can think of would be SharpLab, but you can only choose between Roslyn's git branches instead of C# versions.

TypeScript 5.2's New Keyword: 'using'
Your code is destructuring two properties and discarding one of them. It doesn't work with a single property: https://sharplab.io/#v2:C4LgTgrgdgNAJiA1AHwAICYAMBYAUBgRj2Nw...
I think that records don't generate a deconstruct method when they only have one property, but even if you manually define one you'll get an error on `var (varName) = ...`

Tips for entry-level .net developer?
- LinqPad is great and I love, but, IMO, it is not the best tool to start with. It does not provide intellisense or debugger in the free version. Assuming you do not want to pay for this licence just to play a little with the language, I'd suggest https://sharplab.io/. It is not as powerfull as LinqPad, but at least it gives you suggestions.
