我使用PreEmptive Dotfuscator来模糊我的Android平台Xamarin Forms应用程序。我可以更早地构建应用程序，但当我将Windows升级到10，将VS升级到2019，并使用最新版本的Dotfucator Community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，我就可以成功构建
以下是带有异常详细信息的VS输出：

你必须注意到最初日志中的汉字——我想知道这是否是问题的原因。
我是Dotfuscator团队的成员，并以该身份回答问题。
这看起来是Xamarin Android链接器最近更新后引入的一个新问题。我们正在内部调查，但目前，您可以禁用链接器：
- 在Visual Studio中，右键单击解决方案资源管理器中的Android项目，然后选择属性
- 转到Android选项
- 向下滚动至链接器属性
- 在链接下拉列表中，选择无
(等效的MSBuild属性为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：我们已经就此向Xamarin链接器团队提交了一个问题。再次感谢您引起我们的注意。
