EventHubTrigger 在 Azure Functions 中不起作用

Question

I'm trying to build simple azure functions v2 application that will contain two functions, one is triggered based on TimerTrigger and another that will be triggered by EventHubTrigger . Also I have IoC container configuration using Startup.cs class. TimerTrigger - works fine, but I have some troubles with EventHubTrigger. Here is my setup. EventHubFunction:

namespace BgService
{
    public class MyFunctions
    {
        [FunctionName("MyFunction")]
        public async Task RunAsync([EventHubTrigger("myHubName", Connection = "hub")] string events, ILogger log)
        {

        }
    }
}

local.settings.json:

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "*****",

    "hub": "Endpoint=sb://***.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=***"
  }
}

My Startup.cs:

[assembly: FunctionsStartup(typeof(BgService.Startup))]
namespace BgService
{
    public class Startup : FunctionsStartup
    {


        public override void Configure(IFunctionsHostBuilder builder)
        {
           // SomeConfiguration
        }
    }

When I run my azure function project I get a next error:

[19.07.2019 12:26:23] Microsoft.Azure.WebJobs.Host: Error indexing method 'MyFunction'. Microsoft.Azure.WebJobs.EventHubs: Value cannot be null.
[19.07.2019 12:26:23] Parameter name: receiverConnectionString.

Used version of Microsoft.NET.Sdk.Functions -> 1.0.29

And now the tricky part: When I downgrade the version of Microsoft.NET.Sdk.Functions to 1.0.25 without any modification in code -> it magically starts to work, BUT Startup.Configure() method is not called any more(in version 1.0.29 it is working).

Thanks for any assistance, spent a hours on troubleshooting this problem.

Maybe this could help https://github.com/Azure/Azure-Functions/issues/1299

You should as a workaround downgrade package Microsoft.Azure.EventHubs to 3.0.0
