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

Question

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。此错误不会在每次运行时发生，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时，这是一个非常烦人的错误。

我不确定从哪里开始。关于在哪里寻找调试此错误的任何方向，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：

• 单位：2.6.4
• Xamarin.UITests 版本：2.2.4
• Android 目标框架：8.0
• Visual Studio Professional 2017 for Mac 版本 7.5（内部版本 1254）
• 单声道 5.10.1.47 (2017-12/8eb8f7d5e74)（64 位）
• Xamarin.Android：版本：8.3.0.19（Visual Studio Professional）

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