1 year ago I've attached a minimal repro StackOverflowRepro.zip and confirmed that the issue is similar to the aforementioned #2550 though in this case the issue is that a newer package release of System.ComponentModel.Composition type forwards System.Lazy<T,TMetaData> to netstandard, while the netstandard facade packaged with Xamarin type forwards that type to System.ComponentModel.Composition, which results in the stack overflow while linking. Because this behavior occurs while linking the provided repro solution must be built in Release mode and, for iOS, must not be set to build for the Simulator and must have a Mac paired while building (if you're trying to repro from Visual Studio anyway).
With help from a support rep we also found this ticket on the Cecil repo, similar to the previous issue, which looks to have been resolved with a custom Cecil assembly resolver (XamlCAssemblyResolver). I suspect a fix for this issue would involve making the resolver more aware of the System/Microsoft assemblies being forwarded to/from as they relate to the libraries contained in the Xamarin BCL and its facades.
Since our code is getting this assembly from a transitive reference and we're pretty confident we don't depend on any code paths that require the latest package for MEF in our mobile codebase, we've worked around this issue by adding an explicit PackageReference to the package and setting ExcludeAssets metadata to all.
Example:
<PackageReference Include="System.ComponentModel.Composition" Version="6.0.0" ExcludeAssets="all" />

1 year ago While it's cool that you're attempting to do this and I hope you succeed, Xamarin.Forms will not support .NET 6 so there will be no official support unfortunately. Good luck with this!
Description
We have a mobile app that has started reporting build failures with no changes to the actual code/mobile projects. The only changes come from transitive dependency updates originating from references to our other solutions which we've been migrating from .NET Core 3.1 to .NET 6. At first glance the behavior appears very similar to what's described in #2550 although I tried downloading that solution and was not able to reproduce the issue reported there.
Environment
This issue happens both in local development environments running Visual Studio as well as on Mac build agents in our CI/CD environment. The CI/CD environment is not running the very latest version, but I also have a Mac for local development which is running the latest.
