## 迁移步骤
|
|||
|
|
|
|||
|
|
### Phase 1: 修复窗口装饰 API(高优先级)
|
|||
|
|
|
|||
|
|
1. 重写 `SettingsWindow.ApplyChromeMode()` 使用 Avalonia 12 新 API
|
|||
|
|
2. 重写 `ComponentEditorWindow.ApplyChromeMode()` 使用 Avalonia 12 新 API
|
|||
|
|
3. 批量替换所有 `.axaml` 中的 `SystemDecorations` → `WindowDecorations`
|
|||
|
|
|
|||
|
|
### Phase 2: 修复 MainWindow 编译错误(高优先级)
|
|||
|
|
|
|||
|
|
1. 检查 `MainWindow.ComponentSystem.cs` 中 `centerLeft` 和 `positions` 的作用域问题
|
|||
|
|
2. 检查 `MainWindow.DesktopPaging.cs` 中 `child` 和 `_isThreeFingerOrRightDragSwipeActive` 的作用域问题
|
|||
|
|
3. 确认这些变量是否被意外删除或重命名
|
|||
|
|
|
|||
|
|
### Phase 3: 修复 Avalonia 12 API 变更(中优先级)
|
|||
|
|
|
|||
|
|
1. `App.axaml.cs`: 替换 `BindingPlugins.DataValidators` 的访问方式
|
|||
|
|
2. `DesktopComponentFailureView.cs`: 使用新的剪贴板 API
|
|||
|
|
3. `MonetColorService.cs`: 更新 `Bitmap.CopyPixels` 调用签名
|
|||
|
|
|
|||
|
|
### Phase 4: 修复第三方库变更(中优先级)
|
|||
|
|
|
|||
|
|
1. `SettingsWindow.axaml.cs`: 替换 `FluentIcons.Avalonia.SymbolIconSource` 为 v3 等效 API
|
|||
|
|
|
|||
|
|
### Phase 5: 清理过时属性(低优先级)
|
|||
|
|
|
|||
|
|
1. 批量替换 `Watermark` → `PlaceholderText`(所有 .cs 和 .axaml)
|
|||
|
|
|
|||
|
|
## 验证步骤
|
|||
|
|
|
|||
|
|
* 每阶段修复后运行 `dotnet build LanMountainDesktop.slnx -c Debug`
|
|||
|
|
|
|||
|
|
* 最终运行 `dotnet test LanMountainDesktop.slnx -c Debug`
|
|||
