Question

我正在使用Xamarin Form构建移动应用程序。当我尝试通过右键单击-> Xamarin.Android项目->属性-> Android Manifest在Visual Studio 2019社区中打开AndroidManifest.xml时，出现以下错误，

“尝试加载页面时发生错误。索引在数组的边界之外。”

但是该应用程序运行良好，只是没有在属性中显示Android Manifest。

我尝试再次重新创建Android Manifest，并替换Xamarin.Android中的旧Manifest，但仍然无法解决问题。
我已经删除了Xamarin.Android的bin和obj文件，但问题仍然存在。
我创建了另一个新的Xamarin表单，并尝试从属性中读取AndroidManifest.xml，并且可以读取它。但这并没有在Xamarin Form中显示我的项目

4。我也通过在帮助-> Xamarin->打开日志中检查了Visual Studio中的Xamarin日志。它确实显示了一些错误日志。

谁能帮我解决这个问题

无法在Visual Studio属性中加载android清单（尝试加载页面时发生错误。索引超出了数组的范围。）
