Azure DevOps Pipeline 错误“包 (...) 与 net60 不兼容”

Question

我在 Azure Devops 中有源代码控制和管道。

我的项目有两个目标框架：3.1 和 6。

运行管道时，恢复包时会抛出错误：

##[错误]nuget 命令失败，退出代码(1) 和错误（D:\a\1\s\nuget-tst\src\nuget-tst.csproj 包 Microsoft.Extensions.Configuration.Json 3.1 中的错误。 3 与 net60 (.NETFramework,Version=v6.0) 不兼容。包 Microsoft.Extensions.Configuration.Json 3.1.3 支持： - netcoreapp3.1 (.NETCoreApp,Version=v3.1) - netstandard2.0 (.

我发现克服的唯一方法是将 vmImage 设置为“windows-2019”，但这对我来说似乎很奇怪。为什么它不能与最新版本（windows-latest）一起使用？

类似的事情也发生在我身上。通过在nuget 恢复步骤之前添加 nuget 工具安装程序任务来解决此问题 ：

 - task: NuGetToolInstaller@1
  inputs:
    versionSpec: 
    checkLatest: true

在添加此步骤之前，nuget工具版本非常旧（从nuget恢复任务的输出日志中看到这一行）

Caching tool: NuGet 5.4.0 x64

修改后，相同的日志显示：

Detected NuGet version 6.1.0.106 / 6.1.0 ...
