## 构建问题

### 问题: 编译错误 - 找不到 Windows.Win32 命名空间

**症状:**
```
error CS0246: The type or namespace name 'Windows' could not be found
```

**原因:** CsWin32 尚未生成 P/Invoke 代码

**解决方案:**
```bash
# 清理并重新构建
dotnet clean
dotnet restore
dotnet build
```

首次构建时 CsWin32 会自动生成代码,第二次构建应该成功。

### 问题: NuGet 包还原失败

**症状:**
```
error NU1102: Unable to find package 'XXX' with version (>= X.X.X)
```

**解决方案:**
```bash
# 清理 NuGet 缓存
dotnet nuget locals all --clear

# 强制还原
dotnet restore --force

# 重新构建
dotnet build
```

---

### 问题: 构建时提示 SDK 版本不匹配

**症状:**
```
error NETSDK1045: The current .NET SDK does not support targeting .NET 10.0
```

**解决方案:**

# Windows: 确保安装了 .NET 10 Desktop Runtime
# Linux: 确保安装了必要的图形库
```

---

### 问题: 窗口无法显示或黑屏

**可能原因:**
- 显卡驱动问题
- 渲染模式不兼容

**解决方案:**

```json
{
  "Win32RenderingMode": 1  // 尝试不同的值: 0, 1, 2, 3, 4
}
```

2. **禁用硬件加速:**
```bash
# 设置环境变量
set AVALONIA_RENDERING_MODE=Software
```

---

### 问题: 单实例锁定失败

**症状:** 提示"应用已在运行"但实际没有

**解决方案:**

# Linux/macOS
pkill -9 LanMountainDesktop
```

如果问题持续,删除锁文件:
```
Windows: %TEMP%\LanMountainDesktop.lock
Linux: /tmp/LanMountainDesktop.lock
macOS: /tmp/LanMountainDesktop.lock
```

---

### 问题: 设置无法保存

**症状:** 修改设置后重启应用,设置恢复默认

**诊断:**

## Launcher 问题

### 问题: Launcher 找不到主程序

**症状:**
```
找不到有效的 LanMountainDesktop 版本，可能是安装已损坏。
```

**诊断:**
```bash
# 检查目录结构
ls "C:\Program Files\LanMountainDesktop\"

# 应该看到:
# - LanMountainDesktop.Launcher.exe
# - app-{version}/
```

**解决方案:**

1. **检查 app-* 目录是否存在:**
```bash
ls "C:\Program Files\LanMountainDesktop\app-*"
```

2. **检查主程序是否存在:**
```bash
ls "C:\Program Files\LanMountainDesktop\app-{version}\LanMountainDesktop.exe"
```

3. **重新安装应用**

---

### 问题: OOBE 窗口重复出现

**症状:** 每次启动都显示欢迎页面

**原因:** OOBE 完成标记文件丢失或无法创建

# Linux/macOS:
mkdir -p ~/.local/share/LanMountainDesktop/.launcher/state
touch ~/.local/share/LanMountainDesktop/.launcher/state/first_run_completed
```

---

```

**解决方案:**
1. 强制关闭 Launcher
2. 直接运行主程序测试:
```bash
"C:\Program Files\LanMountainDesktop\app-{version}\LanMountainDesktop.exe"
```
3. 检查日志文件

## 更新问题

```

3. **手动切换版本:**
```bash
# 删除新版本的 .current 标记
Remove-Item "C:\Program Files\LanMountainDesktop\app-{new}\\.current"

# 添加 .current 到旧版本
New-Item -ItemType File -Path "C:\Program Files\LanMountainDesktop\app-{old}\\.current"
```

---

### 问题: 增量更新文件哈希不匹配

**症状:**
```
File hash mismatch for 'XXX.dll'
```

**原因:**
- 文件下载不完整
- 文件损坏

**解决方案:**

1. **删除部分下载的更新:**
```bash
# 删除标记为 .partial 的目录
Remove-Item "C:\Program Files\LanMountainDesktop\app-*" -Recurse -Force -Include *.partial
```

2. **清理更新缓存:**

- 权限不足

**解决方案:**

1. **验证插件包:**
```bash
# .laapp 实际上是 ZIP 文件
unzip -t plugin.laapp
```

2. **检查权限:**
```bash
# 以管理员身份运行 Launcher
```

3. **手动解压安装:**
```bash
# 解压到插件目录
unzip plugin.laapp -d "C:\Program Files\LanMountainDesktop\plugins\{plugin-id}"
```
