VS 2015中的Asp.net核心EF

Question

我遵循ASP.NET核心 - 新数据库在VS 2015下使用Asp.net Core中的EF.但是在安装软件包后得到以下错误.

启动项目'src\CoreMVCWebAPI'是Visual Studio 2015的ASP.NET Core或.NET Core项目.此版本的Entity Framework核心包管理器控制台工具不支持这些类型的项目.

在文档中,它说,它需要VS 2017 RC,我想知道它是否在VS 2015下可用,或者是否有任何解决方法我可以在Asp.net Core或Ado.net中使用EF从SQL DataBase中检索数据.

您无法MSBuild在CSproj(Visual Studio 2015)项目中使用(Visual Studio 2017)包.如果您将Microsoft.EntityFrameworkCore.Tools版本从更改1.1.0-msbuild3-final为例如1.1.0-preview4-final它应该工作

project.json中也不允许注释严格遵守JSON格式.有关更多信息/讨论,请参阅此公告github.com/aspnet/Announcements/issues/24和链接问题.
