Question

我正在使用VS2015社区，我安装了.NET 4.6.01040，并按照these说明安装了ASP.NET 5.

我想开始将一个站点从MVC5迁移到MVC6所附带的所有其他更新，所以我开始使用包含我的Data模型的Entity Class库项目。这就是我的project.json文件的样子：

{
  "version": "1.0.0-*",
  "description": "test.Entities Class Library",
  "authors": [ "me" ],
  "tags": [ "" ],
  "projectUrl": "",
  "licenseUrl": "",
  "frameworks": {
    "net461": {
      "dependencies": { "System.Runtime": "4.0.0.0" }
    },
    "dotnet5.4": {
      "dependencies": {
        "Microsoft.CSharp": "4.0.1-beta-23516",
        "System.Runtime": "4.0.21-beta-23516",
        "System.Linq": "4.0.1-beta-23516"
        "System.Collections": "4.0.11-beta-23516",
        "System.Threading": "4.0.11-beta-23516"
      }
    }
},
  "dependencies": {
    "EntityFramework.Core": "7.0.0-rc1-final",
  }
}

我将框架类型从"net451"更改为"net461"因为我认为这是问题，我也尝试添加对依赖项的引用，但没有运气......

错误发生在这里：

[NotMapped]
public decimal TotalOrders => Math.Round(Orders.Where(x => x.Code.StartsWith("5")
                             .Sum(x => x.Amount),MidpointRounding.AwayFromZero);

完整错误是：

CS0012  The type 'IEnumerable<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.    test.Entity..NET Framework 4.6

关于如何使用新项目类型的任何想法？

      "frameworkAssemblies": {
         "System.Runtime": "4.0.10.0"
      }

    },
    "dotnet5.4": {
       "dependencies": {
       "Microsoft.CSharp": "4.0.1-beta-23516",
       "System.Runtime": "4.0.21-beta-23516",
       "System.Linq": "4.0.1-beta-23516"
       "System.Collections": "4.0.11-beta-23516",
       "System.Threading": "4.0.11-beta-23516"
     }
   }
  },
   "dependencies": {
    "EntityFramework.Core": "7.0.0-rc1-final",
  }
}

Answer 2

net461目标框架名称（TFM）表示完整的桌面.NET Framework，如果要从此框架引用System.Runtime，则需要将"System.Runtime": "4.0.0.0"条目移至{{ 1}}节点。
