Azure function 2.x ILogger与.net core ILogger不兼容吗？

Question

我一直在尝试将. net核心库项目引用到我的Azure函数项目中，以调用. net核心类库中定义的进程之一。

net核心库项目使用ILogger。

但是，每当我尝试运行一个函数时，我都会收到以下错误：

[2019/11/29 1：08：35 上午]“Function1”函数出错：Microsoft.Azure.WebJobs.Host：错误索引方法“Function1”。Microsoft.Azure.WebJobs.Host：无法绑定参数“log”以键入 ILogger'1。确保绑定支持参数 Type。如果使用的是绑定扩展（例如 Azure 存储、ServiceBus、计时器等），请确保已在启动代码（例如生成器）中调用了扩展的注册方法。AddAzureStorage（）， builder.AddServiceBus（），

这是我的代码：

[FunctionName("Function1")]
        public static void Run([TimerTrigger("0 */5 * * * *")] TimerInfo myTimer, ILogger log)
        {
            log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
            // string templateFile = Path.Combine(context.FunctionAppDirectory, "Data", "HelloHttpOutputTemplate.txt");
            Startup.Main(null).Wait();
        }

我还确认我的.net核心项目和函数项目引用了相同版本的ILogger：

'microsoft.extensions.logging.abstractions\3.0.0\lib\netStandard ard2.0'

如果我从function project中移除一个. net核心库项目引用，那么它就可以工作。

更新：

请使用<代码>。net core 3.0。

但仍然会遇到同样的错误：

这是我的. csproj文件：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="librdkafka.redist" Version="1.2.1" />
    <PackageReference Include="Microsoft.Extensions.Configuration" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.EnvironmentVariables" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.FileExtensions" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="3.0.0" />

    </None>
  </ItemGroup>
</Project>

解决方案：

将Microsoft.Extensions.Http、Microsoft.Extensions.Logging.Console、Microsoft.Extensions.Logging.Debug和Microsoft.Extensions.Options的版本从3.0.0降级到2.2.0。然后错误将被解决。

原始答复：

我重复了你错误:

原因:

程序集冲突。关键是最后四个程序集引用。

解决方案：

将它们更改为2.2.0。在我这边工作正常。请在您这边试一试，如果您有困难请告诉我。
