The official OpenTelemetry .NET package renamed AspNetCoreInstrumentationOptions to AspNetCoreTraceInstrumentationOptions

[ChrisDusyk]

Versions

• .NET runtime & version (eg .NET Core, .NET Framework): .NET 8
• Honeycomb OpenTelemetry Distribution: Honeycomb.OpenTelemetry.Instrumentation.AspNetCore and Honeycomb.OpenTelemetry.CommonInstrumentations version 0.29.0-beta, Honeycomb.OpenTelemetry version 1.5.0

Steps to reproduce

1. Install dependencies:

   • [email protected], [email protected], and [email protected]
   • OpenTelemetry.Api.* and OpenTelemetry.Instrumentation.* versions 1.7.x

2. Instrument an ASP.NET 8 application in startup:

   // Add OpenTelemetry config
   var honeycombConfig = builder.Configuration.GetHoneycombOptions();
   builder.Services
   .AddOpenTelemetry()
   .UseAzureMonitor()
   .WithTracing(otelBuilder =>
   {
   	otelBuilder
   		.AddHoneycomb(honeycombConfig)
   		.AddCommonInstrumentations();
   });
   
   builder.Services.AddSingleton(TracerProvider.Default.GetTracer(honeycombConfig.ServiceName));

3. Attempt to start application. It will fail at runtime with this error:

   

Additional context

After picking apart what .AddCommonInstrumentations() sets up, I concluded this error was a bit misleading and the core problem is that AspNetCoreInstrumentationOptions has been renamed to AspNetCoreTraceInstrumentationOptions as part of open-telemetry/opentelemetry-dotnet#5108, which has been released in 1.7.0 of the OpenTelemetry .NET distro packages.

I have an example of where this happens in a repo I was building to do a demo: https://github.com/ChrisDusyk/ObservabilityDemo/blob/main/ObservabilityDemo.Server/Program.cs

@ChrisDusyk we are only using Instrumentation version 1.6.0-beta.3 since any later version comes with the stable HTTP semantic convention breaking changes. See #365. I expect we'll be on 1.6.0-beta.3 for 6 months to give users time to use OTEL_SEMCONV_STABILITY_OPT_IN to handle the transition. For more details checkout https://docs.honeycomb.io/troubleshoot/product-lifecycle/recommended-migrations/migrate-to-opentelemetry-semantic-conventions/.

@TylerHelmuth sounds good, thanks for the explanation! Would it be possible to call that out in docs right now as well? Since Honeycomb.OpenTelemetry.Instrumentation.AspNetCore depends on OpenTelemetry.Instrumentation.AspNetCore (>= 1.6.0-beta.3), NuGet will automatically resolve it to 1.7.1 since that fits in the accepted dependency range. I know this is heavily on the OpenTelemetry folks for introducing breaking changes in a minor version increase, but right now the docs as written will result in the error I ran into.
