Microsoft OData Client Xamarin not working

Does anyone know if and how Microsoft OData Client should work on Xamarin Droid?

This is the NuGet package "Microsoft.OData.Client".

It works great in a console application, even if build packages are contained only in a PCL project.

I am trying through OData v4 code generator.

When launched on Xamarin, this is what I get:

I do not think this package supports Xamarin - from the nuget page:

Targets .NET Core 5 and .NET Portable Lib with support for .NET 4.0, SL 5.0, Win Phone 8, Win Phone 8.1 and Win 8.

I would like to suggest a problem with the library developer for more information about this, as this may be an error if it supports Xamarin:

https://github.com/OData/odata.net/issues

The Component Store has the following component that should work, although some time has passed since it was updated:
