Personal BSc.CSIT (6th sem, TU Nepal, Batch 2080, studied 2083 BS) study-repo by Adarasha Gaihre (aakku106). It is an Obsidian vault of course notes (syllabi + past exam papers) mixed with practice C#/.NET code for the .NET-centric computing subject. It is a knowledge base and learning scratch space, not a shipped application — treat DOTNET code as teaching snippets, not production.

The repo may not hold every note for every subject; the exam-analysis notes are the "what to read" pointers for each course (see below). Course content/syllabus may change over time and notes are not guaranteed up to date. The owner holds no rights to any third-party content included (old question papers, syllabus sources, reference PDFs).

Repo layout

• Root *.md files are Obsidian "hub" notes per course (link back to [[BSc.CSIT]]).
• Per-course dirs CDC/ (Compilers), DOTNET/, E-Com/, E-Gov/, SE/, TW/. Each course dir has a Syllabus.md, an Old_sets/ folder of past TU exam papers by BS year (e.g. 2076.md), and its notes.
• Exam analysis = the highest-signal "what to read" per subject (topic-wise frequency over the old sets, with priority tiers):
  • SE/EXAM.md, TW/EXXAM.md (note double-X), CDC/InternalExams/Exam.md, plus old sets for the rest.
• Notes are Obsidian: use YAML frontmatter (Course, Batch: "2080", Year: "2083", tags) and [[wikilink]] cross-references (incl. anchors like [[Syllabus#Unit X]]). Match this style in new notes; do not convert links to plain markdown.
• Code lives under DOTNET/ as multiple independent projects — there is no .sln and no shared root build.
• Known filename typos are intentional and self-consistent — don't "fix" them: Software Engenearing.md (hub), EXXAM.md (TW), Mode_I.md (SE set), NotificationServive.cs.

.NET projects (each is its own csproj, net10.0 target)

Run dotnet build inside each project directory; do not expect a single solution to build them all. .claude/settings.local.json already whitelists dotnet build.

Additional DOTNET content under DOTNET/:

• Syllabus.md + Old_sets/ (6 sets across years)
• LAB/ — lab task docs (DOTNET_Labs_All.md, DOTNET_Labs_Code.md) + CSIT- Lab *.pdf scanner copies; the .md files are the readable source, PDFs are paper scans
• DB/ADO.NET.md — course note on ADO.NET

DB project quirk

LearnDB/Program.cs reads the connection string from the POSTGRES_CONNECTION_STRING env var, defaulting to Host=localhost;Port=5432;Database=postgres;Username=$USER. It uses EnsureCreatedAsync (no migrations) and calls CanConnectAsync to validate. Expect a "PostgreSQL connection failed" unless a local Postgres is running — falling back safely is intended, not a bug.

Toolchain

• Requires .NET 10 SDK (net10.0); dotnet --version is 10.0.301 on this machine.
• Not an app-prod repo: no lint/test/CI config exists. Build is the only verification step.
• Obsidian vault: .obsidian/ holds only editor settings/themes, no content; frontmatter conventions above are the style to match.

Git

• Single main branch; remote origin (GitHub, aakku106/Bec.CSit_6th_sem).
• bin/, obj/, *.dll are gitignored — never commit build artifacts.
• Commit style from history: short imperative summaries per change (e.g. "Add StudentController and Student model").
