Android and iOS projects fail to reference netstandard2.0-only projects

[paulovila]

Is it possible to add netStandard2 project references in the Droid project?
I'm getting this error:

7>uno.sourcegenerationtasks\1.21.0\build\MonoAndroid\Uno.SourceGenerationTasks.targets(94,3): error : System.InvalidOperationException: The project(s) ButchersQA.ViewModels,GlobeWeigh.Rules,GlobeWeigh.Mvvm,ButchersQA.WebClient,ButchersQA.ClientContracts did not provide any metadata reference. This may be due to an invalid path, such as $(SolutionDir) being used in the csproj; try using relative paths instead.This may also be related to a missing default configuration directive. Refer to the Uno.SourceGenerator Readme.md file for more details.

Thanks for trying out the Uno Platform! This is a known issue, see this FAQ entry.
