xamarin.android - Xamarin UI 测试错误：类型“MonoDevelop.MonoDroid.DeploymentException”未标记为可序列化

问题描述

尝试针对我的 Xamarin.Android 项目在本地运行 UI 测试时，我目前收到以下错误和堆栈跟踪。此错误并非每次运行时都会发生，但非常频繁。清理和重建通常会“修复”它，但是当尝试运行所有测试是套件时，这是一个非常烦人的错误。

我不确定从这里开始。任何关于在哪里寻找调试此错误的方向，或者如果有人知道导致错误的原因，将不胜感激。

系统/框架信息：

设置：System.Runtime.Serialization.SerializationException：在程序集“MonoDevelop.MonoDroid，版本=4.0.0.24，文化=中性，PublicKeyToken=3ead7498f347467b”中键入“MonoDevelop.MonoDroid.DeploymentException”未标记为可序列化。

解决方案

我也遇到了这个问题，对我有用的是卸载设备上的应用程序，然后使用新副本重新安装。值得注意的是，我正在连接一个有一段时间没有使用过的设备，所以它比我当前的应用程序旧了几个版本。
