0 functions found in terminal when creating a .NET 8 isolated Azure Function using VS Code on a Mac

Question

I created a new C# timer function in VS Code using .Net 8 in isolated mode and am getting 0 functions found in the terminal on my Mac.

[2024-03-10T14:43:25.386Z] Reading functions metadata
[2024-03-10T14:43:25.386Z] 0 functions found
[2024-03-10T14:43:25.393Z] 0 functions loaded

I don't see the functions listed here like in some of the demos:

When I do run the debugger this message pops up for a second:

but returns to this:

I read this post (though I'm not migrating) on No job functions found, migrating to .net 8 isolated worker process, but I have "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated" in local.settings.json.

I read this post on Functions on .net5: No job functions found. Try making your job classes and methods public, but my .csproj already has Exe in it.

I read this post on 0 functions loaded for isolated but the attributes on my functions are already using the attribute Function.

There was no answer that I could see to this one A warning "No job functions found..." occurs in Terminal logs when debugging a C# project, but the problem looks similar to mine.

The timer function:

public class SendNotificationTimer
{
    private readonly ILogger _logger;

    public SendNotificationTimer(ILoggerFactory loggerFactory)
    {
        _logger = loggerFactory.CreateLogger();
    }

    [Function("SendNotificationTimer")]
    public void Run([TimerTrigger("*/30 * * * * *")] TimerInfo myTimer)
    {
        _logger.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
        
        if (myTimer.ScheduleStatus is not null)
        {
            _logger.LogInformation($"Next timer schedule at: {myTimer.ScheduleStatus.Next}");
        }
    }
}

program.cs:

using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.DependencyInjection;

var host = new HostBuilder()
    .ConfigureFunctionsWebApplication()
    .ConfigureServices(services => {
        services.AddApplicationInsightsTelemetryWorkerService();
        services.ConfigureFunctionsApplicationInsights();
    })
    .Build();

host.Run();

host.json

{
    "version": "2.0",
    "logging": {
      "logLevel": {
        "default": "Debug"
      },
        "applicationInsights": {
            "samplingSettings": {
                "isEnabled": true,
              "excludedTypes": "Request"
            },
            "enableLiveMetricsFilters": true
        }
    }
}

local.settings.json is:

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
  }
}

.csproj is:


  
    net8.0
    v4
    Exe
    enable
    enable
    _78127464
  
  
    
    
    
    
    
    
    
    
  
  
    
      PreserveNewest
    
    
      PreserveNewest
      Never

I have these relevant extensions in VS Code:

Azure Functions v1.13.4
