This is a repository in order to test (Narrow down) a DotNet Core Extension library issue I'm having with a Xamarin Forms application. The Android app is building and running fine (Tested with Emulator: pixel_2_xl_oreo_8_0_538dpi Android 8.0 - API 26). However the build server is not able to build the solution.
A, seperate, full application has been released and is available on the Google Play Store.
The solution is created with Visual Studio 2019 (Version 16.4.2) using a new Xamarin Forms template and then followed the blog post: https://montemagno.com/add-asp-net-cores-dependency-injection-into-xamarin-apps-with-hostbuilder/
The build server is showing the following issues:
##[error]C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(1808,2): Error XA2002: Can not resolve reference: `Microsoft.Bcl.AsyncInterfaces`, referenced by `Microsoft.Extensions.Hosting.Abstractions`.

I've created a public Team project on my Azure DevOps which can be viewed the this location: https://dev.azure.com/Chroomsoft/XamarinDotNetCoreIssue/_build?definitionId=44&_a=summary
The code is included in this GitHub repository.
The (YAML) build is trigged to run with every push to master.
