[kepboy]

Steps to Reproduce

1. Create .NET Standard 2.0 project
2. NuGet add dependency Xamarin.Essentials
3. Create class that uses (not exposes) OrientationSensor class
4. build assembly
5. Run objcgen on assembly to build iOS framework

Expected Behavior

Generate a framework exposing the assembly classes (but not the ones in Xamarin.Essentials)

Actual Behavior

Get error stated in subject line

Environment

Mac Mini OSX 10.14.5 Visual Studio Community Mac 8.1.1 (build 27) Xcode Embeddinator 0.4.0

Two things:

• Could you attach a project showing the issue?
• Could you run the command in question:

with an additional -r:<PATH_TO_Xamarin.Essentials.dll>?

Hey Chris, I'll put together a project shortly, however, I ran the command and the output it attached.
