AOT failing on a third party nuget we are trying to AOT skip

Start with Microsoft.Android.Sdk.Aot.targets at line 109 and the assertion reported at mono/metadata/metadata.c:1326. Reproduce using WW.Cad_Net6.0, the supplied Android AOT properties, and the WW, WW.Cad, and WW.Pdf assemblies. Done means a confirmed minimal reproduction and a documented fix or workaround for skipping the assemblies.

Android framework version

net8.0-android

Affected platform version

SDK 8.0.300, Android 34.0.147/8.0.100

Description

We have a third party nuget that is failing during AOT - we are trying to skip the assembly but the AOT process still seems to hit an assertion exception and fails the build.

The nuget is,
<PackageReference Include="WW.Cad_Net6.0" Version="6.0.2023.11201" />

It requires a license to use at runtime, but building should be fine.

This is the AOT exceptions we are getting,

We've tried the following to skip the assemblies but neither (and both) don't see to work...

  ...
  <AndroidLinkSkip>WW;WW.Cad;WW.Pdf</AndroidLinkSkip>
  ...

  <ItemGroup>
    <TrimmerRootAssembly Include="WW.Cad" RootMode="library" />
    <TrimmerRootAssembly Include="WW.Pdf" RootMode="library" />
    <TrimmerRootAssembly Include="WW" RootMode="library" />
  </ItemGroup>

This is our full set of properties for release builds with AOT

  </PropertyGroup>

Steps to Reproduce

Haven't been able to confirm in a small project,

1. Add WW.Cad_Net6.0 nuget
2. Enabled AOT
3. Run build.

Did you find any workaround?
