# [[CSharp Intro]]

## 🎯 한 줄 통찰 (One-line insight)
C# is explicitly introduced as sitting in the SAME "C family" lineage as the two languages this wiki just finished (C, C++) plus Java, but with a decisive fork: it's not an independent open standard like C/C++, it's a Microsoft-owned language tied to the .NET Framework — meaning the "which compiler/runtime do I use" question that barely mattered for C/C++ (any standards-compliant compiler works) becomes central for C# (tooling is Microsoft-specific, as the next chapter's Visual-Studio-only "Get Started" flow will confirm). [S1]

## 🧠 핵심 개념 (Core concepts)
- **C# ("C-Sharp")** — an object-oriented programming language created by Microsoft, runs on the .NET Framework. [S1]
- **Family lineage** — has roots in the C family; syntactically close to C++ and Java (explicitly stated, not implied). [S1]
- **History** — first released in 2002; latest version at time of writing is C# 13 (November 2024). [S1]
- **Use cases** — mobile apps, desktop apps, web apps/services/sites, games, VR, database applications. [S1]
- **Why C#** — popularity, ease of learning, huge community support, object-oriented structure enabling code reuse (lowers development cost), and easy migration to/from C/C++/Java due to syntactic closeness. [S1]

## 📖 세부 내용 (Details)
- No prior programming experience is assumed for the tutorial. [S1]
- The explicit "close to C, C++, and Java" claim is the tutorial's own framing for why switching between these languages is easy — a claim this wiki can directly test chapter-by-chapter against the already-completed Topic_C/Topic_CPP/Topic_Java. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **C/C++는 특정 회사 소유가 아니었지만 C#은 Microsoft 소유**: Topic_C/Topic_CPP는 언어 표준이 특정 기업에 종속되지 않았지만(ISO 표준), C#은 Microsoft가 만들고 .NET Framework 위에서 동작하는 언어라는 점이 이번 챕터에서 확인된 근본적 차이 — 이는 다음 챕터(Get Started)에서 Visual Studio 전용 설치 절차로 구체화됨. [S1]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 모바일/데스크톱/웹 앱, 게임, VR, 데이터베이스 애플리케이션 등 광범위한 사용처가 원문에서 나열됨. [S1]

## 💻 코드 패턴 (Code patterns)
없음 — 이 챕터는 코드 예제가 없는 개념 소개 챕터.

## ✅ 검증 상태 및 신뢰도
- **상태:** draft
- **검증 단계:** conceptual
- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)

## 🔗 지식 그래프 (Knowledge Graph)
- **상위/루트:** [[C# Tutorial]]
- **관련 개념:** [[CSharp Get Started]], [[CPP Intro]], [[Java Intro]]
- **참조 맥락:** C# 튜토리얼의 첫 챕터 — Get Started로 이어짐.
