# [[C# Tutorial]]

## 🎯 한 줄 통찰 (One-line insight)
Map of Content (MOC) for the W3Schools C# Tutorial — the root that links every core C# knowledge page in this topic folder. [S1]

## 🧠 핵심 개념 (Core concepts)
- This folder (`Topic_CSharp`) wikifies the C# programming language tutorial, one knowledge page per document, in P-Reinforce v3.1 format — same convention as `Topic_CPP` / `Topic_C` / `Topic_Java` / `Topic_PHP` / `Topic_Python` / `Topic_SQL` / `Topic_W3CSS` / `Topic_HTML` / `Topic_CSS` / `Topic_JavaScript`. [S1]
- **File prefix**: `CSharp_` (not `CS_`, to avoid ambiguity with "Computer Science"), folder `Topic_CSharp`. Source URL slugs use `cs_` and file extension `.php` (verified via curl, same as Topic_C — NOT `.asp` like Topic_CPP). [S1]
- **Scope**: tutorial + "Learning by examples" pages only, scraped from `cs_intro.php`'s sidebar (58 links total, confirmed as the full & final list — no separate `default.php` exists for this category, 404). **Excluded**: `cs_compiler`/`cs_exam`/`cs_examples`/`cs_exercises`/`cs_practice`/`cs_quiz`/`cs_server`/`cs_study_plan`/`cs_syllabus` (meta/index pages), `cs_howto_add_two_numbers` (1 page, reserved for the separate HOW TO category later in the series). Notably, unlike other categories, no `cs_ref_*` reference-dump pages appeared in this sidebar at all. [S1]
- **Progress:** **58 of 58 planned docs complete — C# category done.** [S1]
- Every page roots its Knowledge Graph back to this `[[C# Tutorial]]` node.
