将我的 Azure 函数升级到 .net8 失败，并出现错误 Could not load file or assembly 'System.Linq， Version=8.0.0.0

问：

将我的 Azure Functions 应用从 .NET 6 升级到 .NET 8 时，生成成功，但在运行时出现以下错误System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Linq, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.'

这是我的.csproj：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.2.0" />
    <PackageReference Include="NPOI" Version="2.6.1" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>

如何修复此错误？
