Azure 函数 2 依赖注入抛出错误

Question

I have a simple trigger that is bound to a Service bus topic. I am trying to inject another service into the trigger but i am receiving an error:

Microsoft.Extensions.DependencyInjection.Abstractions: Unable to resolve service for type 'AzureSearchSBTrigger.SimpleClass' while attempting to activate 'AzureSearchSBTrigger.AzureServiceTrigger'.

If it remove the constructor the trigger works correctly and i can receive messages, etc.

This is an Azure function 2 (.net core) with Function Runtime Version: 2.0.12332.0

This is how it is setup (and not working)

The main function :

public AzureServiceTrigger(SimpleClass apiClient)
{
}

[FunctionName("AzureServiceTrigger")]
public async Task Run([ServiceBusTrigger("","",Connection = "SBConnectionString")]Message myQueueItem, ILogger log)
{
}

StartUp

[assembly: WebJobsStartup(typeof(StartUp))]
namespace AzureSearchSBTrigger
{
    internal class StartUp : IWebJobsStartup
    {
        public void Configure(IWebJobsBuilder builder)
        {
            builder.Services.AddSingleton<SimpleClass>();
        }
    }
}

Simple Class

public class SimpleClass
{
    public void Somethingsimple()
    {
    }
}

Answer 1

通过从 1.0.24 -> 1.0.26 更新 nuget 包 Microsoft.NET.Sdk.Functions 来修复

Answer 2

Use anything below Microsoft.NET.Sdk.Functions 3.0.1. I had 3.0.2 and I got this error, I had to downgrade but than again am using ASP.NetCore 2.2, so not sure if that has much to do with it
