Unable to build Xamarin Forms project to iOS with DevExpress XPO

Hi All,
I have posted this on StackOverflow, but to get maximum exposure I am asking here also.
Completely out of ideas.

As soon as DevExpress XPOCore is referenced in my XamarinForms application iOS refuses to build - All other platforms build fine. (Android and UWP)

I must add this issue is apparent when building to my iPad and with the simulator.

All packages selected are latest stable.

I am using the lastest community edition of Visual Studio on windows, which connects to a Mac Mini running the latest macOS (Mojave)

The issue is also apparent when I try to build the DevExpress demos.

As XPO is a free nuget package - I can not ask DevExpress directly for support.

The error message return in visual studio is -

Failed to resolve "System.Drawing.Image" reference from
"System.Drawing.Common, Version=4.0.0.0, Culture=neutral,
PublicKeyToken=cc7b13ffcd2ddd51" DevExpress.Xpo.XamarinFormsDemo.iOS
C:\Program Files (x86)\Microsoft Visual
Studio\2017\Community\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets
From output

1> C:\Program Files (x86)\Microsoft VisualStudio\2017\Community\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(795,3):
error MT2002: Failed to resolve "System.Drawing.Image" reference from

Edit - checked on Mac in /Library/Frameworks/Xamarin.iOS.framework/Versions/Current/lib/mono/Xamarin.iOS/Facades - and System.Drawing.Common exists already.

I do not have enough rep to post any links to anything I have referenced.

Appreciate any help, thanks.
