推荐答案

托管Mac上的默认Mono版本为5.12，这很可能导致此问题.将Bash脚本任务添加到执行以下代码的管道的开头，为我解决了该问题.

The default Mono version on hosted Macs is 5.12 which is most likely causing this issue. Adding a Bash script task to the beginning of the pipeline that executes the code below fixed the issue for me.

/bin/bash -c "sudo $AGENT_HOMEDIRECTORY/scripts/select-xamarin-sdk.sh Latest"

/bin/bash -c "echo '##vso[task.setvariable variable=MD_APPLE_SDK_ROOT;]'/Applications/Xcode_11.2.1.app;sudo xcode-select --switch /Applications/Xcode_11.2.1.app/Contents/Developer"
