c# - 无法加载文件或程序集“Microsoft.Extensions.Logging，版本=7.0.0.0，文化=中性，系统找不到指定的文件”

Question

我正在尝试将 serilog 包含在我的 Azure 函数应用程序项目 (.net 6)、My Startup.cs 中

public override void Configure(IFunctionsHostBuilder builder)
 {
        Log.Logger = new LoggerConfiguration()
        .WriteTo.Console()
        .WriteTo.AzureAnalytics(workspaceId: "xxxxxxxxxxxxxxxxxxxxxxx",
        authenticationId: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
        .CreateLogger();

        builder.Services.AddLogging(lb => lb.AddSerilog(Log.Logger,true));

        ConfigureServices(builder.Services);
    }

    private void ConfigureServices(IServiceCollection services)
    {
        services.RegisterApplicationServices();

    }

我的csproj

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
    <DockerFastModeProjectMountDirectory>/home/site/wwwroot</DockerFastModeProjectMountDirectory>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
</PropertyGroup>
<ItemGroup>
    <PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.1.0" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.2.0" />
    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.18.1" />
    <PackageReference Include="Serilog" Version="3.0.1" />

    <PackageReference Include="Serilog.Sinks.Console" Version="4.1.0" />
</ItemGroup>
<ItemGroup>
    <ProjectReference Include="..\xxxx.Application\xxxxx.Application.csproj" />
</ItemGroup>
<ItemGroup>
    <None Update="host.json">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
        <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
</ItemGroup>

一切似乎都已就位，但我在本地运行应用程序时收到此错误

A host error has occurred during startup operation '677c62b7-bf08-4306-812c-e7ea5fbd5678'.[2023-08-01T15:21:25.432Z] Microsoft.Azure.WebJobs.Script: Error configuring services in an external startup class.

Answer 1

尝试将 Serilog.Extensions.Logging 降级到 3.1.0 版本(在我的示例设置中，我使用的是 Serilog.Extensions.Hosting与 5.0.1 版本依赖它)
