azure-functions-core-tools: System.ComponentModel.Annotatoins Version=4.2.0.0 (doesn't exist)

Originally filed as https://github.com/aspnet/EntityFrameworkCore/issues/12010 by @codputer

I’m attempting to execute an Azure Function, referencing my .Net 2.0 libraries to manage entities in my domain model. The code works in both test project (4.7), as well as a console application (4.7), but when I invoke the same code from Azure Function, I get an error from EntityFramwork that is referencing a Annotation library that does NOT exist… not sure if this should to Azure Functions, but it lists that EF Core cannot load a library - and that library version (4.2.0.0) does not exist.

here is the full stack of the error:
