Could not AOT assembly - When building Xamarin Android project using MSBUILD on Windows

I am building a Xamarin.Android in release mode using an automated build using Azure DevOps

I have AOT turned on with LLVM turned on (I know previously AOT was "Experimental" but I think its not production ready)

I can build my project locally but when using MSBuild I get the following errors:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: System.Data.DataSetExtensions.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Xamarin.Forms.GoogleMaps.Android.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: CarouselView.FormsPlugin.Android.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Syncfusion.Core.XForms.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Plugin.Messaging.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Syncfusion.DocIORenderer.Portable.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: SQLitePCLRaw.provider.e_sqlite3.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Syncfusion.DataSource.Portable.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Microsoft.AppCenter.Analytics.Android.Bindings.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: Plugin.CurrentActivity.dll C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2730,3): Error XA3001: Could not AOT the assembly: SQLite-net.dll

The crux of this error is:

Could not AOT the assembly: AssemblyX.dll

I have tried building on a hosted VM too and I get the same error.

So where does the root cause of this error lie, is it Visual Studio? Xamarin? The Individual Libraries or My Project?

This turned out to be just one assembly causing the error:

System.Data.DataSetExtensions.dll V4.5.0

Found here: https://www.nuget.org/packages/System.Data.DataSetExtensions/4.5.0

After refactoring that library out my solution built fine.
