【问题描述】：
我正在尝试将某些功能移至 Azure Functions。为 EF Core 2 代码创建了一个项目，并将其引用到 Azure Functions 项目。将 EF Core+SQLServer 块包添加到 Azure Functions 项目。当函数试图执行时，这是屏幕上的错误。我可以看到 Microsoft.EntityFrameworkCore 程序集与我们的 azure 函数 dll 位于同一目录中。
谁能解释为什么找不到它以及如何解决这个问题？

更新：2018 年 1 月 3 日
我已经安装了 VS 2017 15.5.2，我正在 VS 中构建它。
这是我从 VS 运行函数主机时的输出。

【问题讨论】：
-
您是否正在编译 .NET Standard 2.0 库并在 Functions 运行时的 v2（预览版）版本上运行？
-
我相信是的，我怎么确定呢？所有这些多平台的东西都让它有点麻烦。
-
在
csproj中检查TargetFramework并运行func -v以查看运行时版本 -
TargetFramework 对于 Azure Function 项目是 netstandard2.0，对于 EF Core 2 项目是 netstandard2.0;net462。我应该从哪里运行 func -v？
-
我用更多信息更新了这个问题，希望能有所帮助。我应该如何为 EF Core 引用我的类程序集？我对每个项目都有两种不同的解决方案，我只是将 Azure Function 项目指向 EF Core 类的 bin\release\netstandard2.0\{assembly} 的输出目录。
