Azure运营模式管道VsTest：错误消息：System.IO.FileNotFoundException：无法加载文件或程序集Mono.Android

Question

使用Moq包模拟接口不适用于Azure运营模式CI Build Pipeline VsTask。Xamarin Nunit测试：VsTask失败并出现错误错误：进程“C：\Program Files（x86）\Microsoft Visual Studio\2017\Enterprise\Common 7\IDE\Common Extension\Microsoft\TestWindow\vstest.console.exe”失败并退出代码1

失败，错误html" target="_blank">消息为：System.IO。FileNotFoundException:无法加载文件或程序集“Mono”。Android，Version=0.0.0.0，Culture=neutral，PublicKeyToken=84e04ff9cfb79065'。系统找不到指定的文件。

池：
vmImage:“vs2017-win2016”
要求：-MBuild Xamarin。AndroidJDK vstest

任务：VSTest@2
输入：测试选择器：“testAssemblies”。dll*测试适配器。dll！\对象
搜索文件夹：
'$（build.binariesdirectory）/$（BuildConfiguration）codeCoverageEnabled:false任务：PublishTestResults@2
displayName:“发布API测试结果”输入：测试结果格式：VSTest测试结果文件：“**/*.trx”

所有测试用例都应在本地Visual Studio 2019上成功执行。以下是生成管道日志中的错误。

@Snehal Jadhav这可能是因为应用程序找不到程序集文件-Mono.Android。在验证以下内容后，您可以重新运行测试吗？

< Li > dll文件的路径配置是否正确？ < li >您不是指 < li >格式不正确的程序集包您使用的是正确的版本。

您可以通过从windows机器查看其详细信息来检查当前dll文件的版本。
