Question

我正在尝试to migrate从AppVeyor到Azure DevOps的小型OSS项目，并且几乎完成了所有工作，但是现在getting this error在dotnet restore步骤上：

NU1100：无法为'.NETStandard，Version = v1.3'解析'System.Reflection.TypeExtensions（> = 4.5.1）'。

尽管我清楚地看到System.Reflection.TypeExtensions支持.NET Standard 1.3：

.NETStandard 1.3
    System.Reflection (>= 4.3.0)
    System.Resources.ResourceManager (>= 4.3.0)
    System.Runtime (>= 4.3.0)

我做错了什么？

更新：my YAML file如下：

trigger:
- master

pool:
  vmImage: 'windows-2019'

variables:
  solution: 'JWT.sln'
  buildConfiguration: 'Release'
  buildPlatform: 'Any CPU'
  dotNetVersion: '2.2.106'

steps:
- task: DotNetCoreInstaller@0
  displayName: Install .NET Core v$(dotNetVersion)
  inputs:
      version: $(dotNetVersion)

- task: DotNetCoreCLI@2
  displayName: 'Restore NuGet packages'
  inputs:
    command: 'restore'
    projects: '**/*.csproj'
    feedsToUse: config
    nugetConfigPath: NuGet.config

- task: DotNetCoreCLI@2
  displayName: 'Build solution'
  inputs:
    command: 'build'
    projects: '$(solution)'
    configuration: '$(buildConfiguration)'

- task: DotNetCoreCLI@2
  displayName: Run .NET Core tests
  inputs:
    command: 'test'
    projects: 'tests/**/JWT.Tests.Core.csproj'
    arguments: ' -c $(buildConfiguration) --no-build --no-restore'
    testRunner: VSTest
    testResultsFiles: '**/*.trx'
    testResultsFormat: 'xUnit'
    failTaskOnFailedTests: true

- task: DotNetCoreCLI@2
  displayName: Run .NET Framework tests
  inputs:
    command: 'test'
    projects: 'tests/**/JWT.Tests.NetFramework.csproj'
    arguments: ' -c $(buildConfiguration) --no-build --no-restore'
    testRunner: VSTest
    testResultsFiles: '**/*.trx'
    testResultsFormat: 'xUnit'
    failTaskOnFailedTests: true

- task: DotNetCoreCLI@2
  displayName: Package NuGet package
  inputs:
    command: pack
    packagesToPack: 'src/**/*.csproj'
    configuration: $(BuildConfiguration)
    nobuild: true

- task: PublishBuildArtifacts@1
  displayName: Publish build artifacts

更新2：我试图分别还原.NET Core和.NET Framework的程序包，但是它不起作用：

  displayName: 'Restore NuGet packages for .NET Core'
  inputs:
    command: 'restore'
    projects: '**/*.csproj'
    feedsToUse: config
    nugetConfigPath: NuGet.config

- task: NuGetCommand@2
  displayName: 'Restore NuGet packages for .NET Framework'
  inputs:
    command: 'restore'
    restoreSolution: $(solution)
    feedsToUse: config
    nugetConfigPath: NuGet.config

- task: DotNetCoreCLI@2
  displayName: 'Build solution'
  inputs:
    command: 'build'
    projects: '$(solution)'
    configuration: '$(buildConfiguration)'

虽然有效的是原始MSBuild，它可以显式还原软件包：

- task: MSBuild@1
  displayName: Build solution
  inputs:
    solution: $(solution)   
    msbuildArguments: /restore /t:build /p:CreatePackage=true /p:NoPackageAnalysis=true /p:PackageOutputPath=$(Build.ArtifactStagingDirectory)\artifacts
    configuration: $(BuildConfiguration)
    maximumCpuCount: true

我认为您的dotnet还原任务不是dotnet还原，而是msbuild / NuGet还原？

特别是，从日志的最后20行开始，我假设此错误与该程序包无关，只是该程序包是它尝试还原的第一个程序包，因此这是错误的地方，真正的问题更多是https://github.com/NuGet/Home/issues/4821这种东西的变体。

诊断步骤1 ：将构建代理容器更改为不带Visual Studio的容器，并查看是否可以修复还原错误。

我肯定有信心（1）对于dotnet核心工具链来说，还原步骤是多余的；以及（2）您必须使用dotnet核心工具链来在您的开发桌面上进行构建？

因此，我认为迁移到Azure的问题可能是：（1）如何建立正确的管道尚不明显；（2）dotnet core / msbuild / nuget交互中可能存在一些错误。

如果使用GUI选项，那么您想要的 only 任务就是dotnet core任务
如果使用YML选项，则首先选择从https://docs.microsoft.com/en-us/azure/devops/pipelines/languages/dotnet-core中提取的片段。该页面上的代码片段等效于在本地计算机上运行dotnet命令，因此可以在本地计算机上进行一些调试。
