+# Multi-Platform Build Guide
+
+This document explains how to build LanMontainDesktop for Windows, Linux, and macOS.
+
+## Overview
+
+LanMontainDesktop supports self-contained builds for:
+- **Windows**: x64 (64-bit) and x86 (32-bit)
+- **Linux**: x64 only (AppImage/snap support planned)
+- **macOS**: x64 (Intel) and arm64 (Apple Silicon M1/M2/M3)
+
+## Build Matrices in CI
+
+The GitHub Actions workflow uses a build matrix to automatically build all combinations:
+
+```yaml
+Windows builds:  win-x64, win-x86 (on windows-latest)
+Linux builds:    linux-x64 (on ubuntu-latest)
+macOS builds:    osx-x64, osx-arm64 (on macos-latest)
+```
+
+Each build:
+- ✅ Restores dependencies
+- ✅ Updates version in csproj
+- ✅ Publishes with optimizations
+- ✅ Creates platform-specific packages
+- ✅ Uploads to release artifacts
+
+## Local Building
+
+### Prerequisites
+
+**All Platforms:**
+```bash
+# Install .NET 10 SDK
+dotnet --version  # Should show 10.0.x
+```
+
+**Linux (Debian/Ubuntu):**
+```bash
+# Install required dependencies
+sudo apt-get update
+sudo apt-get install -y \
+    libfontconfig1 \
+    libfreetype6 \
+    libx11-6 \
+    libxrandr2 \
+    libxinerama1 \
+    libxi6 \
+    libxcursor1 \
+    libxext6 \
+    libxrender1 \
+    libxkbcommon-x11-0
+```
+
+**macOS:**
+```bash
+# Xcode Command Line Tools required
+xcode-select --install
+
+# Or if you have Homebrew:
+brew install dotnet
+```
+
+### Building Locally
+
+**Windows (x64):**
+```powershell
+# Using the PowerShell script
+.\LanMontainDesktop\scripts\package.ps1 `
+    -RuntimeIdentifier win-x64 `
+    -Version 1.0.0
+
+# Or with dotnet directly
+dotnet publish LanMontainDesktop/LanMontainDesktop.csproj `
+    -c Release -r win-x64 -o ./publish/win-x64 `
+    --self-contained -p:PublishSingleFile=true
+```
+
+**Windows (x86):**
+```powershell
+.\LanMontainDesktop\scripts\package.ps1 `
+    -RuntimeIdentifier win-x86 `
+    -Version 1.0.0
+```
+
+**Linux (x64):**
+```bash
+# Make build script executable
+chmod +x scripts/build.sh
+
+# Build
+./scripts/build.sh --rid linux-x64 --version 1.0.0
+
+# Output: ./publish/linux-x64/
+```
+
+**macOS (Intel x64):**
+```bash
+chmod +x scripts/build.sh
+
+./scripts/build.sh --rid osx-x64 --version 1.0.0
+
+# Output: ./publish/osx-x64/
+```
+
+**macOS (Apple Silicon arm64):**
+```bash
+chmod +x scripts/build.sh
+
+./scripts/build.sh --rid osx-arm64 --version 1.0.0
+
+# Output: ./publish/osx-arm64/
+```
+
+## Build Output
+
+After building, you'll have a self-contained directory with:
+
+```
+publish/[rid]/
+├── LanMontainDesktop.exe (Windows)
+├── LanMontainDesktop (Linux/macOS - executable)
+├── libvlc/ (Windows/macOS only)
+├── Localization/ (i18n files)
+├── Extensions/ (Component extension manifests)
+└── Assets/ (Fonts, weather icons, etc.)
+```
+
+### Package Creation
+
+**For Windows:**
+```bash
+# Create zip package
+$rid = "win-x64"
+$version = "1.0.0"
+$dir = "LanMontainDesktop-$version-$rid"
+Copy-Item -Path "./publish/$rid" -Destination $dir -Recurse
+Compress-Archive -Path $dir -DestinationPath "$dir.zip"
+```
+
+**For Linux/macOS:**
+```bash
+# Create tar.gz package
+rid=linux-x64
+version=1.0.0
+dir="LanMontainDesktop-$version-$rid"
+mkdir -p $dir
+cp -r ./publish/$rid/* $dir/
+tar -czf "$dir.tar.gz" $dir
+```
+
+## Cross-Compilation Considerations
+
+### ⚠️ Limitations
+
+- **Windows builds must run on Windows** (or in WSL2 with additional setup)
+  - libvlc has platform-specific native libraries
+  - Windows-specific dependencies in vcpkg
+
+- **Linux builds must run on Linux**
+  - Different library paths and system dependencies
+
+- **macOS builds must run on macOS**
+  - Code signing / notarization (if needed) requires macOS
+
+### ✅ Workaround Options
+
+1. **GitHub Actions** (Recommended)
+   - Automatically runs on the correct OS for each build
+   - No local cross-compilation needed
+
+2. **Docker** (For Linux on any platform)
+   - Use container-based build environment
+   - Example: `ghcr.io/classisland/philia-build-image:main`
+
+3. **CI/CD Pipeline**
+   - Let Actions handle all platform builds
+   - Download artifacts locally for testing
+
+## Platform-Specific Notes
+
+### Windows
+
+- Supports both x64 and x86 architectures
+- Uses libvlc from `VideoLAN.LibVLC.Windows` NuGet package
+- Includes MSVC runtime if needed
+
+**Unsupported:**
+- ARM64 (would need separate toolchain)
+
+### Linux
+
+- Tested on Ubuntu 22.04+
+- Requires X11 libraries (no Wayland support yet)
+- Self-contained includes .NET runtime
+- Uses libvlc system libraries or bundled version
+
+**Planned:**
+- AppImage format
+- Snap package
+- .deb packaging
+
+### macOS
+
+- Supports both Intel (x64) and Apple Silicon (arm64)
+- Uses libvlc from `VideoLAN.LibVLC.Mac` NuGet package
+- Universal binary support (both architectures in one file) - not yet implemented
+
+**Planned:**
+- DMG packaging
+- Code signing & notarization
+- App Store distribution
+
+## Troubleshooting
+
+### Windows Build Fails
+
+```bash
+# Clean and retry
+dotnet clean LanMontainDesktop/LanMontainDesktop.csproj
+dotnet restore
+dotnet publish LanMontainDesktop/LanMontainDesktop.csproj -c Release -r win-x64 --self-contained
+```
+
+### Linux Build Fails
+
+```bash
+# Check dependencies are installed
+ldd ./publish/linux-x64/LanMontainDesktop | grep "not found"
+
+# Install missing libraries
+sudo apt-get install -y lib[missing-name]
+```
+
+### macOS Build Fails
+
+```bash
+# Ensure correct .NET version for ARM/Intel
+dotnet --version
+
+# Try specifying explicit SDK version
+export DOTNET_ROOT=/usr/local/share/dotnet
+./scripts/build.sh --rid osx-arm64 --version 1.0.0
+```
+
+## Performance & Size
+
+| Platform | RID | Size | Notes |
+|----------|-----|------|-------|
+| Windows x64 | win-x64 | ~150-200 MB | Includes .NET + libvlc |
+| Windows x86 | win-x86 | ~140-190 MB | Smaller footprint |
+| Linux x64 | linux-x64 | ~120-170 MB | Minimal deps included |
+| macOS Intel | osx-x64 | ~130-180 MB | Intel-optimized |
+| macOS Silicon | osx-arm64 | ~120-170 MB | Apple Silicon native |
+
+*Sizes vary based on trimming and included dependencies*
+
+## Optimization Options
+
+For smaller, faster builds, you can adjust publish settings:
+
+```bash
+# Aggressive trimming (may break reflection-based features)
+-p:PublishTrimmed=true
+
+# Embed debug symbols (larger, but better debugging)
+-p:DebugType=embedded
+
+# AOT compilation (Windows only, faster startup)
+-p:PublishAot=true
+
+# Single executable (already enabled in workflows)
+-p:PublishSingleFile=true
+```
+
+## Distribution
+
+After building, distribute the packages:
+
+1. **Windows users**: Download `.zip`, extract, run executable
+2. **Linux users**: Download `.tar.gz`, extract, run executable
+3. **macOS users**: Download `.tar.gz`, extract, run executable
+
+Plan for future:
+- Installer generation (.exe for Windows, .deb for Linux)
+- Code signing for macOS
+- Auto-update mechanism

+# GitHub CI/CD Workflow Setup Guide
+
+## Overview
+
+This document describes the CI/CD workflows configured for LanMontainDesktop. These workflows are designed to maintain code quality, automate testing, and streamline the release process.
+
+## Workflows
+
+### 1. Build & Test (`build.yml`)
+**Trigger:** Every push/PR to main branches, or manual dispatch
+
+**What it does:**
+- Builds both LanMontainDesktop and RecommendationBackend in Debug and Release modes
+- Runs unit tests (if available)
+- Uploads build artifacts for inspection
+- Runs on Windows (windows-latest)
+
+**Branch Coverage:** main, master, dev, develop
+
+### 2. Code Quality (`code-quality.yml`)
+**Trigger:** Pull requests and pushes to main branches, or manual dispatch
+
+**What it does:**
+- Builds projects with analysis
+- Checks code formatting using `dotnet format`
+- (Optional) Can integrate with Qodana for professional code analysis
+
+**Branch Coverage:** main, master, dev, develop
+
+**Optional: Qodana Integration**
+Uncomment the Qodana step in the workflow and add your token as a secret:
+```bash
+# In GitHub > Settings > Secrets > Actions
+QODANA_TOKEN=your_token_here
+QODANA_ENDPOINT=https://qodana.cloud
+```
+
+### 3. Release & Publish (`release.yml`)
+**Trigger:** Push git tags (v1.0.0, release-1.0.0), or manual workflow dispatch
+
+**What it does:**
+- Builds for **Windows** (x64, x86) - self-contained executables
+- Builds for **Linux** (x64) - tar.gz packages
+- Builds for **macOS** (x64, arm64) - universal support
+- Publishes optimized release builds for all platforms
+- Generates GitHub Release with all platform artifacts
+- Supports pre-release versions
+
+**Supported Platforms:**
+| Platform | Architectures | Output Format | Status |
+|----------|---------------|---------------|--------|
+| Windows | x64, x86 | .zip | ✅ Full support |
+| Linux | x64 | .tar.gz | ✅ Full support |
+| macOS | x64, arm64 (Apple Silicon) | .tar.gz | ✅ Full support |
+
+**Build Scripts:**
+- Windows: Uses PowerShell (`LanMontainDesktop\scripts\package.ps1`)
+- Linux/macOS: Uses Bash (`scripts/build.sh`)
+
+**Usage:**
+
+*Create a full release for all platforms:*
+```bash
+git tag v1.0.0
+git push origin v1.0.0
+# Automatically triggers Windows + Linux + macOS builds
+```
+
+*Manual trigger with selective platforms:*
+Go to GitHub > Actions > Release & Publish > Run workflow
+- Specify version: `1.0.0`
+- Toggle build targets as needed:
+  - ✅ Build Windows (x64/x86)
+  - ✅ Build Linux (x64)
+  - ✅ Build macOS (x64/arm64)
+- Check pre-release option if needed
+
+### 4. Issue Management (`issue-management.yml`)
+**Trigger:** Daily at 1:30 AM UTC, or manual dispatch
+
+**What it does:**
+- Automatically marks inactive issues as "stale"
+- Closes old stale issues/PRs after grace period
+- Issues with `need-more-info` or `waiting-for-response` labels
+- Grace period: 14 days to stale, 7 days before close
+- PR grace period: 21 days to stale, 14 days before close
+
+## Repository Secrets & Configuration
+
+To enable all workflows, configure these GitHub secrets:
+
+### Required
+None - the workflows use default GitHub token
+
+### Optional (for enhanced features)
+1. **Qodana Integration**
+   - Go to GitHub Settings > Secrets > Actions
+   - Add `QODANA_TOKEN` from https://qodana.cloud
+
+## Local Development Setup
+
+To align with CI workflows, set up your local environment:
+
+```bash
+# Install .NET 10 SDK
+# https://dotnet.microsoft.com/download/dotnet/10.0
+
+# Restore dependencies
+dotnet restore
+
+# Build (like CI does)
+dotnet build LanMontainDesktop/LanMontainDesktop.csproj
+dotnet build LanMontainDesktop.RecommendationBackend/LanMontainDesktop.RecommendationBackend.csproj
+
+# Format code locally (required by CI)
+dotnet format
+
+# Run tests
+dotnet test LanMontainDesktop/LanMontainDesktop.csproj
+dotnet test LanMontainDesktop.RecommendationBackend/LanMontainDesktop.RecommendationBackend.csproj
+
+# Alternative: Use local build scripts (Linux/macOS)
+./scripts/build.sh --rid linux-x64 --version 1.0.0
+./scripts/build.sh --rid osx-x64 --version 1.0.0
+
+# Or on Windows with the PowerShell script
+./LanMontainDesktop/scripts/package.ps1 -RuntimeIdentifier win-x64 -Version 1.0.0
+```
+
+### Cross-Platform Build Scripts
+
+**Linux / macOS:**
+```bash
+# Make script executable first
+chmod +x scripts/build.sh
+
+# Build for Linux
+./scripts/build.sh --rid linux-x64 --version 1.0.0
+
+# Build for macOS x64
+./scripts/build.sh --rid osx-x64 --version 1.0.0
+
+# Build for macOS ARM64 (Apple Silicon)
+./scripts/build.sh --rid osx-arm64 --version 1.0.0
+
+# Full help
+./scripts/build.sh --help
+```
+
+**Windows:**
+```powershell
+# Using PowerShell script
+.\LanMontainDesktop\scripts\package.ps1 -RuntimeIdentifier win-x64 -Version 1.0.0
+
+# Or use dotnet directly
+dotnet publish LanMontainDesktop/LanMontainDesktop.csproj `
+    -c Release -r win-x64 -o ./publish/win-x64 `
+    -p:PublishSingleFile=true --self-contained
+```
+
+## Pull Request Process
+
+1. **Create a branch** from `dev` or `develop`
+   ```bash
+   git checkout -b feature/your-feature
+   ```
+
+2. **Make your changes** and test locally
+   ```bash
+   dotnet build
+   dotnet format  # Important!
+   dotnet test
+   ```
+
+3. **Push and create a PR**
+   - The PR template will guide you
+   - Fill out all required sections
+   - Link related issues
+
+4. **Checks will run automatically:**
+   - CI builds in Debug & Release
+   - Code quality checks
+   - Code formatting validation
+
+5. **Review and merge**
+   - Address any feedback
+   - Wait for all checks to pass
+   - Merge to `dev` or `main` as appropriate
+
+## Release Process
+
+### For Stable Releases
+```bash
+# On main branch
+git tag v1.0.0
+git push origin v1.0.0
+# GitHub Actions will automatically create the release
+```
+
+### For Pre-releases
+1. Go to Actions tab
+2. Select "Release & Publish" workflow
+3. Click "Run workflow"
+4. Enter version (e.g., 1.0.0-beta)
+5. Check "Mark as pre-release"
+6. Click "Run workflow"
+
+## Monitoring
+
+### Status Badge
+Add to your README.md:
+```markdown
+![Build Status](https://github.com/YOUR_ORG/LanMontainDesktop/workflows/Build%20&%20Test/badge.svg)
+```
+
+### Check Workflow Status
+- GitHub > Actions tab
+- View workflow runs and logs
+- See build artifacts
+
+## Troubleshooting
+
+### Build Failures
+1. Check the workflow logs in GitHub Actions
+2. Try building locally with same .NET version
+3. Ensure all submodules are initialized: `git clone --recursive`
+
+### PR Checks Not Running
+- Ensure branch is up-to-date with main
+- Review branch protection rules in Settings
+- Check if workflows are enabled in Actions
+
+### Release Creation Failed
+- Verify tag format (v*.* or release-*.*)
+- Check that csproj files are in correct format
+- Review workflow output for specific errors
+
+## Future Enhancements
+
+Consider adding:
+- Test coverage reporting
+- Performance benchmarking
+- Automated versioning (CalVer/SemVer)
+- Multi-platform builds (Linux, macOS)
+- Installer generation (.exe, .msi)
+- Automated changelog generation
+- Docker images for backend

+
+### 构建脚本
+
+| 脚本 | 平台 | 功能 |
+|------|------|------|
+| `LanMontainDesktop\scripts\package.ps1` | Windows | 现有PowerShell打包脚本 |
+| `scripts\build.sh` | Linux/macOS | 新增跨平台构建脚本 |
+
+### 配置文件
+
+| 文件 | 用途 |
+|------|------|
+| `.gitattributes` | 行尾处理，确保跨平台兼容 |
+| `.github/CODEOWNERS` | 代码所有权定义 |
+| `.github/pull_request_template.md` | PR提交规范 |
+| `.github/ISSUE_TEMPLATE/*.md` | Issue模板 |
+| `.github/WORKFLOWS_GUIDE.md` | 工作流使用指南 |
+| `.github/MULTIPLATFORM_BUILD.md` | 多平台构建详细指南 ⭐ |
+
+## 🚀 快速开始
+
+### 1. 验证工作流正常运行
+```bash
+# Push到main分支
+git add .github/
+git commit -m "feat: Add GitHub CI/CD workflows"
+git push origin main
+
+# 检查GitHub Actions是否自动运行
+# https://github.com/YOUR_ORG/LanMontainDesktop/actions
+```
+
+### 2. 创建第一个Release（可选）
+```bash
+# 本地修改版本号（如果需要）
+# 然后创建tag
+git tag v1.0.0
+git push origin v1.0.0
+
+# GitHub Actions会自动：
+# 1. 更新版本号
+# 2. 构建Release版本
+# 3. 创建可执行文件
+# 4. 生成GitHub Release
+```
+
+### 3. 配置分支保护规则（推荐）
+在 GitHub > Settings > Branches > Branch Protection Rules：
+- 要求CI检查通过再merge
+- 要求PR审查
+- 要求代码最新
+
+## ⚙️ 配置选项
+
+### 可选：启用Qodana代码分析
+
+1. 访问 https://qodana.cloud
+2. 注册并创建organization token
+3. 在GitHub > Settings > Secrets > Actions 中添加：
+   - `QODANA_TOKEN`
+   - `QODANA_ENDPOINT=https://qodana.cloud`
+4. 在 `.github/workflows/code-quality.yml` 中取消Qodana步骤注释
+
+### 自定义构建参数
+
+编辑 `.github/workflows/` 中的yml文件：
+- `DOTNET_VERSION` - 改变.NET版本
+- 分支列表 - 改变监控的分支
+- 矩阵配置 - 添加更多构建配置
+
+## 📊 工作流对比与选择
+
+### Build日语言表
+| 工作流 | 触发条件 | 运行时间 | 成本 |
+|--------|---------|--------|------|
+| Build | 每个push/PR | ~2-3分钟 | 低 |
+| Code Quality | PR/push | ~2-3分钟 | 低 |
+| Release | Tag push | ~5-10分钟 | 中 |
+| Issue Mgmt | 每天1次 | ~1分钟 | 很低 |
+
+### 预计月度GitHub Actions使用
+- **小项目**(<5贡献者): 100-200 runner hours
+- **中等项目**(5-20贡献者): 300-500 runner hours  
+- **大项目**（>20贡献者): 800+ runner hours
+
+> 💡 **免费额度**: 2000 runner hours/月 (对大多数开源项目足够)
+
+## 🔍 故障排查
+
+### 工作流不运行？
+- [ ] 检查 `.github/workflows/*.yml` 语法（YAML缩进）
+- [ ] 确认分支名称配置正确
+- [ ] 查看Actions标签查看错误日志
+- [ ] 检查分支保护规则是否冲突
+
+### 构建失败？
+```bash
+# 本地重现CI环境
+dotnet clean
+dotnet restore
+dotnet build LanMontainDesktop/LanMontainDesktop.csproj -c Release
+```
+
+### PR检查无法通过？
+1. 本地运行 `dotnet format`
+2. 确保没有编译警告
+3. 所有测试通过
+

+## 🛠️ 配置与优化
+
+### 必需配置
+✅ 无需额外配置！工作流开箱即用
+
+### 可选配置
+
+**启用 Qodana 代码分析:**
+1. 访问 https://qodana.cloud
+2. 创建 organization token
+3. 在 GitHub Settings > Secrets > Actions 添加：
+   - `QODANA_TOKEN` = your_token
+   - `QODANA_ENDPOINT` = https://qodana.cloud
+4. 编辑 `.github/workflows/code-quality.yml`，取消 Qodana 步骤注释
+
+**配置分支保护规则:** （强烈推荐）
+1. 访问 Settings > Branches > Branch Protection Rules
+2. 要求通过以下检查：
+   - ✅ Build & Test
+   - ✅ Code Quality
+3. 要求代码审查后再合并
+4. 驳回过期分支
+
+## 🐛 故障排查
+
+### Release 工作流不运行？
+- 检查标签格式：`v1.0.0` 或 `release-1.0.0`
+- 确认 csproj 文件格式正确
+- 查看 Actions 日志获取详细错误
+
+### 特定平台构建失败？
+- **Windows**: 检查 libvlc 依赖
+- **Linux**: 确保依赖库已安装
+- **macOS**: 检查 Xcode 命令行工具
+
+### 包大小过大？
+- 启用 `PublishTrimmed=true` 缩小 IL 代码
+- 考虑关闭符号信息：`DebugType=none`
