vNext无法在引用的包中看到命名空间

Question

Program.cs的

using System;
using RazorEngine;

namespace ConsoleApp1
{
    public class Program
    {
        public static void Main(string[] args)
        {
            string template = "Hello @Model.Name! Welcome to Razor!";
            string result = Razor.Parse(template, new { Name = "World" });
            Console.WriteLine(result);
            Console.WriteLine("Press enter to exit.");
            Console.ReadLine();
        }
    }
}

project.json

{
  "version": "1.0.0-*",
  "dependencies": {
    "RazorEngine": "3.4.2"
  },
  "commands": {
    "run": "run"
  },
  "frameworks": {
    "aspnet50": {},
    "aspnetcore50": {
      "dependencies": {
        "System.Console": "4.0.0-beta-*"
      }
    }
  }
}

当我运行kpm build时，我得到此输出（仅包含相关信息）

Building RazerEngineTester for Asp.Net,Version=v5.0
Using Project dependency RazerEngineTester 1.0.0
Source: /Users/mason/Desktop/Dot Net Solutions/RazerEngineTester/project.json

Using Package dependency RazorEngine 3.4.2

Source: /Users/mason/.kpm/packages/RazorEngine/3.4.2

Program.cs(2,7): error CS0246: The type or namespace name 'RazorEngine' could not be found (are you missing a using directive or an assembly reference?)

为什么我得到这个编译错误，即使它正确地拉下了RazorEngine NuGet包，according to the source code，RazorEngine命名空间存在？

Answer 1

如果仔细观察Razor.Parse方法，它会说下面的事情。

它适用于asp.net 5.0但不适用于核心。

现在，如果从project.json中删除框架，那么它将起作用。

   {
    "version": "1.0.0-*",
    "dependencies": {
        "RazorEngine": "3.4.2"
    },
    "commands": { 
        "run" : "run"
    },
    "frameworks" : {
        "aspnet50" : { }        
    }
}

Answer 2

我注意到即使我收到了编译错误，如果我运行k run那么它也会运行正常。所以我意识到aspnetcore50框架无法构建，但我还是不关心那个，并且aspnet50框架编译得很好。所以我修改了我的project.json文件以删除该框架并且它有效。

{
  "version": "1.0.0-*",
  "dependencies": {
    "RazorEngine": "3.4.2"
  },
  "commands": {
    "run": "run"
  },
  "frameworks": {
    "aspnet50": {}
  }
}
