Description

When using the Grace Dependency Injection container with any version of OTEL beyond 1.7.0, I get an exception.

Steps to Reproduce

<ItemGroup>
    <PackageReference Include="Grace.AspNetCore.Hosting" Version="7.1.0" />
    <PackageReference Include="OpenTelemetry.Exporter.OpenTelemetryProtocol" Version="1.8.0" />
    <PackageReference Include="OpenTelemetry.Extensions.Hosting" Version="1.8.0" />
</ItemGroup>

Program.cs

using Grace.AspNetCore.Hosting;
using OpenTelemetry.Trace;

var builder = WebApplication.CreateBuilder(new WebApplicationOptions());

//Comment out and the service starts
builder.Host.UseGrace();

builder.Services.AddOpenTelemetry().WithTracing(tracerProviderBuilder =>
{
    tracerProviderBuilder.AddOtlpExporter();
});

var app = builder.Build();

app.MapGet("/hello", () =>
    {
        return "hello";
    })
    .WithName("hello");

app.Run();

Expected Result

The service should start, and the /hello endpoint returns "hello"

Actual Result

The service fails to start, and I get the following exception:

Additional Context

This combo has been working since the early Otel days, only recent versions have stopped working. Otel 1.7.0 now has a medium vulnerability so management is looking to move to a newer version soon.

@secovel - Do you know if the library Grace calls UseExporter internally?

Calling UseOtlpExporter and AddOtlpExporter together is not supported as noted in the error.

System.NotSupportedException: Signal-specific AddOtlpExporter methods and the cross-cutting UseOtlpExporter method being invoked on the same IServiceCollection is not supported.

[secovel]

Grace doesn't have any OpenTelemetry references or specific coding. The line of code that triggers the issue is just telling Grace to populate the DI container. Worked fine in every version up till 1.8. I haven't debugged far enough into the Container code to see exactly what is triggering the exception.

I was reading some other issues, seems like it could be related to This Unity Container thread?

Is there a way to turn off the check that was implemented in 1.8 that is causing the code to fail completely? Or perhaps implement the change recommended in that thread.

@CodeBlanch - Any insights on this?

[secovel]

Looks like that is exactly the problem. I see a registration of a concrete type where it should probably be an interface, then the guard code wouldn't be triggered.

[CodeBlanch]

I haven't looked at Grace yet. First I've ever heard of it 🤣 My guess would be it is the same issue as the Unity one linked above. When using M.E.DI if you call sp.GetServices<T>() it only returns you things which were registered. Using Unity and Grace (assuming) it actually goes and creates/instantiates a service even if nothing was registered. IMO these are bugs in those containers they shouldn't have different behavior(s) from the standard implementation.

I'll see if there is maybe another API which works more consistently, if adding a private ctor or something will fix this, otherwise we can go to an interface registration.

The bigger issue I have here is trying to prevent future issues/regressions. We don't want to have CI covering every possible DI container which exists or may exist and we don't want to spend our valuable time chasing down issues in components which are not widely used 🤔
