Issue Description

In my project I'm using some features of Xamarin IOS 12.2 (Mono 5.16), but the agent has Default Mono Version: 5.12.0 so if I try to make the build directly it fails.

In order to fix that I've included the script to change the Xamarin SDK as detailed here:

- script: sudo $AGENT_HOMEDIRECTORY/scripts/select-xamarin-sdk.sh 5_16_0
  displayName: 'Select Xamarin SDK version'

But when adding that the build breaks showing that the Xamarin.iOS task failed because it couldn't find MSBuild or xbuild. It seems to be related to #5885 but if I set it to Stable instead of 5_16_0 the task fails again.

Added before XamariniOS@2:

- script: /bin/bash -c "sudo $AGENT_HOMEDIRECTORY/scripts/select-xamarin-sdk.sh 5_16_0"
- script: /bin/bash -c "echo '##vso[task.setvariable variable=MD_APPLE_SDK_ROOT;]'/Applications/Xcode_10.1.app;sudo xcode-select --switch /Applications/Xcode_10.1.app/Contents/Developer"

and it worked perfectly thanks
