Android Dotfuscator根检查导致Xamarin中的EncoderCallbackException

我使用先发制人的Dotfuscator来混淆我在Android平台上的Xamarin表单应用程序。我能够更早地构建应用程序，但当我将Windows升级到10而不是2019并使用最新版本的Dotfucator社区版本时，相同的DotfuscatorConfig.xml开始出现异常

如果我从DotfuscatorConfig.xml文件中删除根检查，我就能够成功构建。

以下是VS输出以及异常详细信息：

您必须注意到初始日志中的中文字符-我想知道这是否是问题的原因。

我是Dotfuscator团队的成员，并以该身份回答

这看起来是Xamarin Android链接器最新更新引入的新问题。我们正在进行内部调查，但目前，您可以禁用链接器：

在VisualStudio中，在解决方案资源管理器中右键单击Android项目并选择属性

转到Android选项

向下滚动到链接器属性

在“链接”下拉列表中，选择“无”

（等效的MSBuild属性是

AndroidLinkMode

，设置为

None

）

如果使用此设置进行构建，则应该能够再次注入根检查

更新：我们已经与Xamarin链接器团队就此进行了沟通。再次感谢您提请我们注意
