[Bug]: System.InvalidOperationException thrown when registering with AddResiliencePipeline in .NET 8 Isolated Function App

[CSharpFiasco]

Describe the bug

Seems to be related to the following bug in the .NET 8 runtime: https://github.com/dotnet/runtime/issues/95789.

Expected behavior

I would expect the function app to register the single event hub trigger

Actual behavior

Exception thrown: 'System.InvalidOperationException' in Microsoft.Extensions.DependencyInjection.Abstractions.dll
An unhandled exception of type 'System.InvalidOperationException' occurred in Microsoft.Extensions.DependencyInjection.Abstractions.dll
This service descriptor is keyed. Your service provider may not support keyed services.

Steps to reproduce

using Microsoft.Extensions.Hosting;
using Polly;
using Polly.Retry;

var host = new HostBuilder()
    .ConfigureFunctionsWorkerDefaults()
    .ConfigureServices((builder, services) =>
    {
        services.AddResiliencePipeline("my-pipeline", (resiliencePipeLineBuilder, context) =>
        {
            resiliencePipeLineBuilder.InstanceName = "my-pipeline";
            resiliencePipeLineBuilder.AddRetry(new RetryStrategyOptions());
        });
    })
    .Build();

host.Run();

.NET Version

8.0.204

Anything else?

I've based my code around the following guidelines: https://learn.microsoft.com/en-us/azure/azure-functions/dotnet-isolated-process-guide?tabs=windows#start-up-and-configuration. Let me know if you'd like me to spin up a simplified project

[peter-csala]

I tried to reproduce the issue in a console application.

• When I run the application without the ConfigureFunctionsWorkerDefaults call then it works fine without any exception.
• When I run the application with the ConfigureFunctionsWorkerDefaults call then I get a different InvalidOperationException:

System.InvalidOperationException: The gRPC channel URI 'http://:' could not be parsed.

I don't see anything which is Polly related in either StackTraces.

Could you please run your code but now without the AddResiliencePipeline call?
