Project does not recognize references library

Hi, I have a project "TestProject" and a library "TestLib", the project reference my library and it works perfectly.
Currently I've installed "nugget Google Ads" on "TestProject", it works!

Now I want the nugget of "Google Ads" doesn't belong to the project and belong to my library.
Thus, any of my projects that uses my library include "Google Ads".

I deleted nuggets "Google Ads" from "Test Project" and I added this in "TestLib", BUT it doesn't work...
How should I do it?
I received errors about not finding resources and now the last error that says something like:

The type or namespace name 'Gms' does not exist in the namespace 'Android' (are you missing an assembly reference?) TestProject.Droid

    It sounds like TestLib is a project included in the same solution as TestProject. If that's true, then I expect the following:

    • You can reference the NuGet package in TestLib and use it's API with no issue.
    • You cannot use any API from that NuGet package in TestProject because it does not have a direct reference to the package.
    • If you want to use GoogleAds in TestProject, you need to add the NuGet package to that project too.

    The NuGet in TestLib only covers use in TestLibs source.

    Thank you for answering so quickly @John !

    I don't understand why I can't add a nugget to "TestLib" and use it directly in "TestProject", because "TestProject" can use all the classes that I've created in "TestLib".

    For example, on Android Studio I had this same case and it worked.
    "TestLib" also included my classes, several libs like GoogleAds, GoogleAnalytics...
    And "TestProject" import "TestLib" and I could use all it.

    I am not familiar enough with Java and AndroidStudio to know how that works in comparison. However, take a look at this question which has a few answers that I think help explain now .NET works.
