빠르게 다운 받아 맛봐야겠네요. 업데이트도 하고!

C# 13 에 추가된 새로운 기능은 뭔가 마른 걸레 짜내기 같네요.

이제 어지간한 건 다 적용했나 봅니다.

Chris_Shim · November 13, 2024, 12:56am

부족한 기능이 한가득인데
C# 9 같은 대격변이 다시 오기를

BigSquare · November 13, 2024, 1:20am

대표적으로 부족하다고 알려진 건 어떤 게 있을까요?

dimohy · November 13, 2024, 1:48am

아마 field value 같은 기능이지 않을까 해요. 이 기능은 몇 년을 기다리고 있는데 되게 추가가 안되네요. 저 은퇴하고 추가 하려고 하는 듯

Chris_Shim · November 13, 2024, 1:54am

몇년이나 기다리고 있는 C# 기능이 한가득이죠

개인적으로는 아래 proposal이 반영되어야 모던 언어 형태를 완성한다고 생각하고 있습니다. Rust, 코틀린, typescript, scala, f# 모두 가지고 있죠.

dotnet/csharplang/blob/main/proposals/TypeUnions.md

# Type Unions for C#

* [x] Proposed
* [ ] Prototype: [Not Started](pr/1)
* [ ] Implementation: [Not Started](pr/1)
* [ ] Specification: [Not Started](pr/1)

## Summary
[summary]: #summary

A proposal for type unions (aka discriminated unions) in C#.

## Motivation

When developing software you may encounter situations where the values that you want to store in a variable are not always the same kind each time through. While you are usually not concerned about storing strings and numbers in the same spot, you may need to store one of a few related types depending on what that data is meant to represent at that moment.

For example, your application may have both a customer and a supplier definition that share only some of the same properties and you may need to perform a similar operation on both in a fashion that depends on the differences. 

Typically, this is where you might choose to distribute those specialized implementations into the types themselves and expose them through common abstract methods or interfaces. However, this is only good practice when those types exist primarily for the purpose of the operation or it makes sense for the operation to appear as an intrinsic part of the type. If the types have a broader purpose, polluting them with methods like this can be undesirable.

와 드디어 정식판! (하지만 아직 어떻게 써야 할지…)

dimohy · November 14, 2024, 12:53pm

오. LangVersion을 preview로 하면 field를 사용할 수 있나 보네요!

이렇게 또 보일러플레이트를 하나 없애주는 MS…
