C# 使用Xamarin调试Android应用程序时出错

今天我尝试使用Xamarin创建一个Android应用程序。当我构建解决方案时，我不会得到任何错误报告。但是，不幸的是，当我尝试调试它时，应用程序停止工作，我得到以下错误输出：

你可以看到，有一条线：

AOT module 'System.Runtime.Serialization.dll.so' not found: dlopen failed: library "/data/app-lib/system.mil.newsreader.system.mil.newsreader-2/libaot-System.Runtime.Serialization.dll.so" not found

这个问题有什么解决办法吗

您是否尝试删除bin和obj文件夹，然后重新生成。是的..，我已经这样做了..，但不幸的是问题仍然存在。我还尝试使用nuget重新安装appcompat，但仍然没有任何结果….，“AOT模块”System.Runtime.Serialization.dll.so“找不到：dlopen失败：”。。。这里也有同样的问题。在xamarin论坛（）中有一条关于它的线索，但这里似乎也没有一条
