SQL :无法定位依赖项EntityFramework.Relational

Question

我试图用Visual 2015在ASP.NET 5应用程序(MVC 6)中安装实体框架。

我在Package控制台中运行了以下命令来安装SQLServerCompact3.5

Install-Package EntityFramework.SqlServerCompact35 –Pre

结果是成功的

Installing NuGet package EntityFramework.SqlServerCompact35.7.0.0-rc1-final.
Successfully installed 'EntityFramework.SqlServerCompact35 7.0.0-rc1-final' to Web

但是，包的恢复失败。

该应用程序的目标是1.0.0-Rc1-update1DNX版本。

project.json中的依赖项是

"EntityFramework.SqlServerCompact35": "7.0.0-rc1-final",
"Microsoft.AspNet.Diagnostics": "1.0.0-rc1-final",
"Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
"Microsoft.AspNet.Server.IIS": "1.0.0-beta7",
"Microsoft.AspNet.Server.WebListener": "1.0.0-rc1-final",
"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final",
"Microsoft.Framework.DependencyInjection": "1.0.0-beta8"'

你能告诉我什么是问题吗？
