从 .NET 6 升级到 .NET 8 时出现错误“无法加载文件或程序集 'Microsoft.Extensions.Configuration，Version=8.0.0.0'”

Question

我目前正在尝试将 API 存储库从 .net6.0 更新到 .net8.0，并将 Cosmos 数据库从 2.13.1 更新到 3.35.4。我相信数据库升级很好，API 的应用服务也很好。这只是更改提要功能在尝试本地测试时出错。这是第一个更新到 8.0 的存储库，因此这是一次学习经历。 首先，这是我收到的错误。

这是我尝试过的：

• 查看了所有包，查找 Microsoft.Extensions.Configuration 的定义位置。
• 加载了该包的 8.0.0 版本，希望它能够覆盖定义了较低版本的任何其他包。

我发现 Microsoft.Extensions.Configuration 包在我们的 nuget 包 Columbia.Cosmos.Common 中的域级别定义，以及在 Microsoft.Azure.Functions.Extensions 的函数级别定义。

这是域级别的 csproj 文件：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
      <GenerateTargetFrameworkAttribute>false</GenerateTargetFrameworkAttribute>
    <ImplicitUsings>disable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <Compile Remove="Consumer\**" />
    <EmbeddedResource Remove="Consumer\**" />
    <None Remove="Consumer\**" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="cdtservicecommon" Version="[*,9999.0]" />
    <PackageReference Include="Columbia.Cosmos.Common" Version="3.1.0" />
    <PackageReference Include="Microsoft.ApplicationInsights" Version="2.20.0" />
    <PackageReference Include="Microsoft.Azure.Cosmos" Version="3.46.0" />
    <PackageReference Include="Microsoft.NETCore.App" Version="2.2.8" />

  </ItemGroup>

</Project>

这是更改提要功能的 csproj 文件：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Azure.Messaging.ServiceBus" Version="7.7.0" />
    <PackageReference Include="Columbia.ServiceBus.Common" Version="2.0.0" />
    <PackageReference Include="csc.azure.datalake.client" Version="4.0.0-preview1" />
    <PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.1.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.CosmosDB" Version="3.0.10" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.ServiceBus" Version="5.2.0" />
    <PackageReference Include="Microsoft.Extensions.Http.Polly" Version="6.0.3" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.0.1" />
    <PackageReference Include="Polly" Version="7.2.3" />
    <PackageReference Include="Polly.Contrib.WaitAndRetry" Version="1.1.1" />
  </ItemGroup>
  <ItemGroup>
    <ProjectReference Include="..\cscentconsumer.infrastructure\cscentconsumer.infrastructure.csproj" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

最后，这是出错函数的startup.cs：

                                        .Build();

            builder.Services.AddDatalakeClient(options => config.Bind(options));

            builder.Services.AddSingleton(config);

            builder.Services.AddCosmosDb(
                config.GetValue<string>("cosmosdb-connection"),
                options =>
                {
                    options.DatabaseId = config["CosmosDb:DatabaseId"];
                    options.Containers = config["CosmosDb:Containers"].Split(',').ToList();
                },
                cosmosResiliencySettings: config.GetValue<CosmosResiliencySettings>("CosmosResiliencySettings"));

            builder.Services.AddOptions();
            builder.Services.Configure<ConsumerServiceDetails>(config.GetSection("ServiceDetails"));

            builder.Services.AddSingleton<IMessageBuilderUtility, MessageBuilderUtility>();
        }
    }
}

将组件版本

Microsoft.NET.Sdk.Functions

升级至 4.5.0，将

Microsoft.Azure.WebJobs.Extensions.CosmosDB

升级至 4.8.1。

在

 "FUNCTIONS_INPROC_NET8_ENABLED": "1"

中添加

local.settings.json

。

local.settings.json：

{
    "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_INPROC_NET8_ENABLED": "1",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "COSMOS_CONNECTION": "<CosmosDB_Connection_String>"
  }
}

.csproj： 将所有软件包更新到最新版本。

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>

我已经创建了一个 .NET 8.0 Cosmos DB 触发器 Azure 函数，并且能够获得预期的响应。

Functions:

        Function1: cosmosDBTrigger

For detailed output, run func with --verbose flag.
