.NET 6 System.IO.FileNotFoundException: 无法加载文件或程序集 System.Linq，版本 =6.0.0.0

Question

我正在尝试将项目从 .NET Core 3.1 迁移到 .NET 6。我已经关注了 official migration guide from Microsoft.

在构建期间 startup.Configure 我得到

System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Linq, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.'

这是.csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AzureFunctionsVersion>v3</AzureFunctionsVersion>
    <AssemblyName>Omicron.Insurance.Runner</AssemblyName>
    <RootNamespace>Omicron.Insurance.Runner</RootNamespace>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Omicron.Insurance.Entities" Version="1.0.139" />
    <PackageReference Include="Omicron.Platform.Web.ApplicationInsights" Version="3.1.60" />
    <PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.1.0" />
    <PackageReference Include="Microsoft.Azure.ServiceBus" Version="5.2.0" />

  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">

    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

Answer 1

我不得不将 AzureFunctionsVersion 从 v3 更新到 v4。那解决了这个问题。 Microsoft 的官方迁移指南中没有提到升级 Azure Functions。

编辑：您还需要升级 Azure Function App。
