+# Repository Guidelines
+
+## Project Structure & Modules
+- Solution: `v2rayN/v2rayN.sln` (C#/.NET 8)
+- Apps: `v2rayN/v2rayN` (Windows WPF), `v2rayN/v2rayN.Desktop` (Avalonia cross‑platform)
+- Core library: `v2rayN/ServiceLib` (models, services, `Resx` resources)
+- Hotkeys: `v2rayN/GlobalHotKeys` (library + examples); tests in `GlobalHotKeys.Test`
+- Artifacts: `v2rayN/Release/`, `v2rayN/publish/`, `build-output/`
+- Packaging scripts (root): `package-*.sh`
+
+## Build, Test, and Development
+- Prerequisites:
+  - .NET 8 SDK on all platforms.
+  - Building the WPF app (`v2rayN/v2rayN`) requires the Windows Desktop targeting pack. Install via `dotnet workload install windowsdesktop` or use a Windows machine with Visual Studio build tools.
+- Build all projects (no publish artifacts): `dotnet build v2rayN/v2rayN.sln -c Release`
+- Run Avalonia app (Linux/macOS/Windows): `dotnet run --project v2rayN/v2rayN.Desktop -c Debug`
+- Run WPF app (Windows only): `dotnet run --project v2rayN/v2rayN -c Debug`
+- Publish (examples):
+  - Avalonia Linux x64 self-contained: `dotnet publish v2rayN/v2rayN.Desktop/v2rayN.Desktop.csproj -c Release -r linux-x64 --self-contained true -o v2rayN/Release/linux-64`
+  - WPF Windows x64 self-contained: `dotnet publish v2rayN/v2rayN/v2rayN.csproj -c Release -r win-x64 -p:EnableWindowsTargeting=true --self-contained true -o v2rayN/Release/windows-64`
+  - Use other runtime identifiers (`win-arm64`, `osx-x64`, etc.) similarly.
+- Tests (NUnit): `dotnet test v2rayN/GlobalHotKeys/src/GlobalHotKeys.Test -c Release --collect:"XPlat Code Coverage"`
+
+### Quick Linux x64 build (single executable)
+
+Minimal commands to produce a self-contained Linux x64 executable (with normal output):
+
+```
+git submodule update --init --recursive
+dotnet publish v2rayN/v2rayN.Desktop/v2rayN.Desktop.csproj \
+  -c Release -r linux-x64 --self-contained true \
+  -o v2rayN/Release/linux-64
+echo ./v2rayN/Release/linux-64/v2rayN
+```
+
+## Coding Style & Naming
+- Formatting from `.editorconfig`: UTF-8, CRLF, spaces=4.
+- C#: file‑scoped namespaces; System usings first; braces required; prefer `var` when type is apparent; PascalCase for types/members; fields/private locals use camelCase.
+- Lint/format: `dotnet format` before pushing.
+- XAML/Avalonia: keep views thin; move logic to ViewModels in `ServiceLib`/`*ViewModels`.
+
+## Testing Guidelines
+- Framework: NUnit with `GlobalHotKeys.Test`.
+- Conventions: classes `*Tests`, methods `[Test]` with Arrange/Act/Assert; keep tests isolated and deterministic.
+- Run locally with `dotnet test` and ensure coverage for hotkey registration/ID reuse.
+
+## Commit & Pull Requests
+- Commits: short imperative subject (e.g., "Fix…", "Update…"), optional scope, reference issues/PRs (e.g., `(#8123)`).
+- PRs must include: problem summary, rationale, user impact, steps to verify, screenshots for UI, target OS/runtime.
+- CI parity: changes must pass `dotnet build` and `dotnet test` locally; do not commit artifacts under `Release/` or `publish/`.
+
+## Security & Configuration
+- Do not commit secrets or downloaded core binaries; rely on packaging scripts/CI.
+- Submodules: clone/update with `--recursive` when needed.
+- Keep platform‑specific code isolated (Windows WPF vs Avalonia) to avoid regressions.
+
+## Agent Notes
+- Follow this file’s scope for style and layout; keep patches minimal and targeted.
+- Prefer simplifying data flow over adding conditionals; avoid deep nesting.
