Azure函数2.x ILogger不能与.net核心ILogger竞争？

Question

我一直试图将一个.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。

然而，每当我试图运行一个函数时，我都会得到以下错误：

29/11/2019 1:08:35上午'Function1‘函数出错: Microsoft.Azure.WebJobs.Host:错误索引方法’function 1‘。Microsoft.Azure.WebJobs.Host:无法将参数'log‘绑定到ILogger`1 `1类型。请确保绑定支持参数类型。如果使用绑定扩展(例如Azure存储、ServiceBus、计时器等)确保您已经为启动代码中的扩展调用了注册方法(例如builder.AddAzureStorage()、builder.AddServiceBus()，

这是我的密码：

[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核心项目以及函数项目都引用了相同版本的ILogger：

'microsoft.extensions.logging.abstractions\3.0.0\lib\netstandard2.0‘

如果我从函数项目中删除了一个.net核心库项目引用，那么它就能工作。

我的函数CS项目文件：

  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>

更新：

现在就使用.net core 3.0吧。

​

​

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" />
    <PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.DependencyInjection.Abstractions" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Http" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Console" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="3.0.0" />
    <PackageReference Include="Microsoft.Extensions.Options" Version="3.0.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.28" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </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降为2.2.0。那么错误就会被解决。

原始答案：

我重述了你的错误：

​

​

事业：

大会冲突。关键是您的最后四个程序集引用。

解决方案：

将它们更改为2.2.0。对我来说一切都很好。请试一试，如果你有困难，请告诉我。
