如何在Visual Studio 2015中使用引用的netstandard1.5库项目修复智能感知

Question

我有四个库项目，它们都针对netstandard1.5框架。其中一些依赖于另一个，智能感知在这四个项目下运行良好。

我正在尝试在我的 ASP.NET netcoreapp1.0项目中使用这些库。但是当我以netcoreapp1.0框架为目标时，找不到类型（在视觉工作室中标出红色）。项目 hower 编译并成功运行。

一旦我切换到 Web API 中的netstandard1.5框架，库的类型就会被识别出来，并且我得到了智能感知。

关于如何解决此问题或我做错了什么的任何想法？

以下是其中一个库项目的project.json（它们几乎相同）：

{
  "version": "1.0.0-*",
  "frameworks": {
    "netstandard1.5": {
      "imports": [ "dnxcore50", "portable-net45+win8" ],
      "dependencies": {
        "NETStandard.Library": "1.5.0-rc2-24027",
        "System.Security.Principal": "4.0.1-rc2-24027"
      }
    }
  },
  "dependencies": {
    "Microsoft.AspNetCore.Identity": "1.0.0-rc2-final",
    "Microsoft.EntityFrameworkCore": "1.0.0-rc2-final",
    "HoehenSucht.Models": "1.0.0-*",
    "Microsoft.NETCore.Portable.Compatibility": "1.0.1-rc2-24027"
  }
}

这是 API 的project.json：

  },

    }
  }
}

Answer 1

Resharper是这里的问题，而不是Visual Studio。

http://blog.jetbrains.com/dotnet/2016/05/27/resharper-ultimate-2016-2-eap-kicks-off/

对 ASP.NET Core 1.0 RC2 的初始支持，包括在代码完成、导航、搜索和重构方面对标记帮助程序的支持。此时，如果 ASP.NET 核心 Web 应用程序面向 .NET Framework，则支持它们，但如果它们面向 .NET Core，则不支持这些应用程序。我们希望在后续版本中对此进行改进。

因此，如果你有一个面向.netstandard1.5 Resharper的库将无法正确显示智能感知信息，但项目将编译。

但是，如果您将.netcoreapp1.0框架作为附加框架添加到project.json文件中，Resharper 将起作用，您将获得完整的智能感知支持。

        "System.Security.Principal": "4.0.1-rc2-24027"
      }
    },
