Unable to archive app if it references a .NET Standard 2.0 class library

Description

We noticed an issue with a larger project where the code would not archive using the Visual Studio For Mac 2022 GUI. I realize this is possibly a tooling issue, but regardless I think it’s important to raise here.

Given a MauiApp that is ready for release, with no issues I would expect it to be able to be built for Release and able to be Archived, instead the following error occurs:

Assets file '/Users/axemasta/Documents/GitHub/MauiArchiveReproduction/src/MyClassLib/obj/project.assets.json' doesn't have a target for 'net6.0-maccatalyst'. Ensure that restore has run and that you have included 'net6.0-maccatalyst' in the TargetFrameworks for your project.

The project in question is a .net standard 2.0 project, it should have no knowledge of mac catalyst (which coincidentaly is the target on the visual studio gui).

Steps to Reproduce

I have reproduced this issue in a sample repo: MauiArchiveReproduction, reproduce by:

• Building for release

@breenbob Same result unfortunately, command: dotnet publish -f:net6.0-ios -c:Release /p:ArchiveOnBuild=true /p:RuntimeIdentifier=ios-arm64
