[martincostello]

Bug Report

List of all OpenTelemetry NuGet packages and version that you are using (e.g. OpenTelemetry 1.0.2):

• OpenTelemetry 1.8.0
• OpenTelemetry.Exporter.OpenTelemetryProtocol 1.8.0
• OpenTelemetry.Extensions.Hosting 1.8.0
• OpenTelemetry.Instrumentation.AWS 1.1.0-beta.3
• OpenTelemetry.Instrumentation.AWSLambda 1.3.0-beta.1
• OpenTelemetry.Instrumentation.Http 1.8.0

Runtime version: net9.0

Symptom

Compiling a native AoT application with .NET 9 preview 2 fails when OpenTelemetry 1.8.0 is used in the application.

What is the expected behavior?

The application successfully compiles.

What is the actual behavior?

The application fails to compile due to warnings associated with the DelegatingOptionsFactoryServiceCollectionExtensions type:

This doesn't occur with .NET 8 - unless there's a bug with the native AoT compiler, my assumption is that new annotations have been added to the runtime in .NET 9 which create new warnings/incompatibilities.

Reproduce

Originally found with martincostello/alexa-london-travel@3a0e406 with /p:TrimmerSingleWarn=false.

For a simpler repro see verify-aot-compat failures in #5519 (example).

Additional Context

None.

Looks like this isn't specific to .NET 9 after all - #5520 shows it fails against main and .NET 8.
