⚠️我已经在dotnet/standard
中创建了一个问题问题已使用简化的代码参考进行更新，您可以在自己的环境中重现该问题。 （自述文件中提供了VSTS设置的屏幕截图）
到目前为止，一切都在LOCAL环境中正常运行。 当我在 Visual Studio Team Services 上运行构建时，它会抛出错误/ s
[error]src\Ninja.Dojo\Fight.cs(18,19): Error CS0012: The type 'IServiceProvider' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

你的packages.config是什么样的？我想您可能想要添加NETStandard.Library，以便在运行nuget restore时下载程序集：https://www.nuget.org/packages/NETStandard.Library/
答案 1 :(得分：0)
Microsoft.NETCore.Platforms软件包用于此目的：
提供解决.NETCore程序包的目标框架，平台和特定于运行时的实现所需的运行时信息。
