C# 引用.NET标准1.6项目时，.NET 4.7 xunit测试项目无法生成

因此，我有一个包含2个项目的简单解决方案：

• .NET标准1.6类库
• .NET4.7框架类库，带有用于测试的xUnit

现在，当我尝试在本地构建（在VS2017中）时，一切正常

在Visual Studio Online/Team Services上构建时，会出现大量错误：-

[command]"C:\Program Files\dotnet\dotnet.exe" build d:\a\1\s\src\Hornet.Services\Hornet.Services.csproj -c release /p:Version=1.0.0
Microsoft(R) Build Engine version 15.1.1012.6693

Hornet.Services -> d:\a\1\s\src\Hornet.Services\bin\release\netstandard1.6\Hornet.Services.dll

Build succeeded.
    0 Warning(s)
    0 Error(s)

/\___工作！（不是NS1.6版本）

要在同一解决方案中构建的下一个项目

而我认为VSTS正在使用

1.0.2

我相信我找到了我的答案->我正在尝试执行以下步骤，所有步骤都以为目标。NET CORE：

恢复

建造

试验

打包

但这些都是.NET的核心步骤。。测试项目是一个.NET4.7项目

所以我没有建立测试项目。。。这就是它出错的原因！该死

非常尴尬

因此，TL；博士；/这里的要点是仔细检查VSTS构建步骤，并确保它们针对的是正确的项目。

尝试在您的代理上安装VS2017预览您的意思是

代理队列：托管VS2017

？这就是当前值。不完全正确！我的意思是创建一个安装了vs2017预览版的私有代理！不难，但要让它工作起来有点假！查看这里的发行说明，框架/标准/核心互操作仅在preview3中引入。不确定更新了什么工具以允许此操作。希望有更多的人能帮助你。同时，您可以创建一个VSTS任务，以便在构建步骤之前安装最新的预览NetCore工具，并查看其中的帮助！
