VSTS构建任务在.NetFramework4.6.1项目引用.NetStandard2.0上失败

Question

⚠️ I already created an issue in dotnet/standard

🚨 Question has been updated with simplified code reference that you may reproduce it on your own environment. (Screenshots of VSTS settings are available in readme file)

• a .Net Framework 4.6.1 project that references .NetStandard2.0 (not preview) project
• Visual Studio 2017 Update 3 (not preview, VisualStudio.15.Release/15.3.0+26730.3)

so far everything is working fine in LOCAL environment. When I run a build on Visual Studio Team Services it throws the error/s below

Error message

[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'.

Projects

1. libraries .Net Standard 2 projects will create Nuget file upon build.
2. host a .Net Framework 4.6.1 project that references libraries from the 1st project.

Please advise 🤗

Answer 1

What does your packages.config look like? I think you might want to add the NETStandard.Library so that assembly is downloaded when you run nuget restore: https://www.nuget.org/packages/NETStandard.Library/

Answer 2

Microsoft.NETCore.Platforms package is used for this purpose:

Provides runtime information required to resolve target framework, platform, and runtime specific implementations of .NETCore packages.
