IEnumerable的＆LT;＆GT;新的NuGet类库项目

本文介绍了IEnumerable的＆LT;＆GT;新的NuGet类库项目 - 在未引用的程序定义的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用VS2015的社区，我安装了.NET 4.6.01040我也跟着的这些说明安装ASP.NET 5。

I'm using VS2015 Community, I have .NET 4.6.01040 installed and I followed these instructions to install ASP.NET 5.

我要开始MVC5一个站点迁移到MVC6所有附带的其他更新，所以我就开始与持有我的数据模型实体类库项目。这是我的 project.json 文件的样子：

I want to start migrating a site from MVC5 to MVC6 all the other updates that came with it, so I started with the Entity Class library project that holds my Data model. This is how my project.json file looks like:

{ "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", } }

我从变化框架类型net451到net461，因为我认为这是问题，我也试图引用添加到依赖，但没有运气...

I changed the framework type from "net451" to "net461" cause I thought that that was the problem, and I also tried to add the reference to the dependencies, but no luck...

该错误是发生在这里：

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

完整的错误是：

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

如何使这项工作与新的项目类型的任何想法？

Any idea on how to make this work with the new project types?

推荐答案

net461 目标框架名（TFM）再presents完整的桌面.NET Framework和若你想从这个框架中引用 System.Runtime ，你需要移动System.Runtime：4.0.0.0进入 frameworkAssemblies 节点。

net461 target framework name (TFM) represents the full desktop .NET Framework and if you want to reference System.Runtime from this framework, you need to move the "System.Runtime": "4.0.0.0" entry to frameworkAssembliesnode.
