VSTS - Xamarin iOS Build - How to choose the mono version to use?

问题

I'm building a Xamarin iOS project on the Hosted macOS Preview queue of VSTS. The log shows that it uses mono 5.8.0. However, the queue specs show that mono 5.10.0 is installed.

The question is how can to choose the version of mono to use (amongst those installed) to build a xamarin ios project on vsts?

UPDATE

Itried the following after @valdetero's answer

- task: XamariniOS@2
    displayName: 'Building iOS'
    inputs:
        solutionFile: '**/*.sln'
        configuration: 'Release'
        mdtoolFile: '/Library/Frameworks/Mono.framework/Versions/5.10.1/bin'

However, I got that error:

[error]Xamarin.iOS task failed with error Error: Unable to locate executable file: '/Library/Frameworks/Mono.framework/Versions/5.10.1/bin'.

回答1:

In your Xamarin.iOS task, open Advanced, check MSBuild, and look at build tool path. Specify an installed version of mono here. I used this for an old project where I can't build it with Mono 5. Here's what I have in the box:

/Library/Frameworks/Mono.framework/Versions/4.8.1/bin

Put that entire path in the box.
