升级 Microsoft.NET.Sdk.Functions 后，“Mono.Cecil.TypeReference”类型的对象无法转换为“System.Type”类型

Question

在 dotnet 8 Azure Function 项目中，由于存在漏洞，我必须升级包

Microsoft.NET.Sdk.Functions

，从

4.0.0

到

4.5.0

。

升级这个包会导致一个奇怪的错误，其要点是：

Object of type 'Mono.Cecil.TypeReference' cannot be converted to type 'System.Type'

这是包含所有详细信息的完整错误消息：

此外，单击 Visual Studio 中的错误消息，将光标移至以下部分：

[UserFolder]\.nuget\packages\microsoft.net.sdk.functions\4.5.0\build\Microsoft.NET.Sdk.Functions.Build.targets

:

<GenerateFunctions
  TargetPath="$(TargetDir)bin\$(TargetFileName)"
  OutputPath="$(TargetDir)"
  UserProvidedFunctionJsonFiles="@(UserProvidedFunctionJsonFiles)"
  FunctionsInDependencies="$(FunctionsInDependencies)"
  TaskAssemblyDirectory="$(_FunctionsTasksDir)"/>

我想知道是否有人有类似的升级此软件包并克服此问题的经历？

Answer 1

该问题可能是由于软件包版本、SDK 和功能核心工具之间的版本兼容性问题，或者由于您正在安装的软件包版本中生成或处理元数据的方式发生了变化，请参阅类似问题。

如果进程内模型项目使用 4.5.0 版本的

Microsoft.NET.Sdk.Functions

，应使用 4.0.6517 或更高版本的 Function Core Tools。

卸载现有版本的Function core工具并安装最新版本。

安装核心工具的命令：

npm i -g azure-functions-core-tools@4 --unsafe-perm true

删除

%LocalAppData%\AzureFunctionsTools

文件夹并重新启动 Visual Studio。

• 清理并重建项目。

我创建了一个 .NET 8.0 Azure 函数。 在 local.settings.json 中添加

"FUNCTIONS_INPROC_NET8_ENABLED": "1",

。

local.settings.json：

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

.csproj：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <AzureFunctionsVersion>v4</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="4.5.0" />
  </ItemGroup>
  <ItemGroup>
    <None Update="host.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="local.settings.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <CopyToPublishDirectory>Never</CopyToPublishDirectory>
    </None>
  </ItemGroup>
</Project>
