.NET8升级至.NET10后WPF应用发布运行缺失WindowsFormsIntegration程序集问题

将WPF应用从.NET 8升级到.NET 10后，本地运行正常，但发布到其他电脑运行时抛出未处理的调度程序异常，核心错误为找不到WindowsFormsIntegration程序集。当前通过在启动项目中设置<UseWindowsForms>True</UseWindowsForms>可以解决，但希望找到其他替代方案。

替代解决方案 #

1. 直接引用WindowsFormsIntegration NuGet包 #

在启动项目中添加对WindowsFormsIntegration NuGet包的引用，发布时会自动包含该程序集，无需启用整个Windows Forms框架。

• 操作：在项目的NuGet包管理器中搜索WindowsFormsIntegration并安装，或在项目文件中添加以下代码：

<PackageReference Include="WindowsFormsIntegration" Version="8.0.0" />

（版本号可根据.NET 10兼容的最新版本调整）

2. 手动包含程序集到发布输出 #

若不想使用NuGet包，可手动复制程序集到发布目录：

• 从本地.NET安装目录找到WindowsFormsIntegration.dll（通常路径为C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App\10.0.x.x\WindowsFormsIntegration.dll）
• 将该文件添加到项目中，设置“复制到输出目录”属性为“始终复制”或“如果较新则复制”
• 发布时文件会被包含到输出文件夹中

3. 移除不必要的WPF-WinForms集成引用 #

异常提示XAML解析时触发了对WindowsFormsIntegration的依赖，可能是项目中存在未使用的WinForms相关代码：

• 检查所有XAML文件，移除未使用的xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"命名空间或WindowsFormsHost控件
• 清理项目中未使用的WinForms相关代码、资源，避免编译时引入不必要的程序集依赖

4. 调整发布裁剪设置（若启用裁剪） #

如果发布时启用了程序集裁剪，可能导致WindowsFormsIntegration被误裁剪，需在项目文件中添加配置保留该程序集：

<ItemGroup>
  <TrimmerRootAssembly Include="WindowsFormsIntegration" />
</ItemGroup>
