如何修复 EF7 中的此错误？

Question

我正在尝试开始 EF7。

我收到以下错误：

这是我的 packages.config:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework.Commands" version="7.0.0-rc1-final" targetFramework="net452" />
  <package id="EntityFramework.Core" version="7.0.0-rc1-final" targetFramework="net452" />

  <package id="Microsoft.Extensions.Configuration.Binder" version="1.0.0-rc1-final" targetFramework="net452" />

  <package id="System.Diagnostics.DiagnosticSource" version="4.0.0-beta-23516" targetFramework="net452" />
  <package id="System.Diagnostics.Tracing" version="4.0.0" targetFramework="net452" />
  <package id="System.Runtime" version="4.0.0" targetFramework="net452" />
  <package id="System.Threading" version="4.0.0" targetFramework="net452" />
</packages>

如您所见，EF.Core 已在此处声明。

我也有一个警告

The 'packages' element is not declared.

那么问题是什么？

注意：我正在使用 Windows 10 Pro 和 VS Enterprise 2015。

Answer 1

您必须删除 EF.SqlServer 并安装 EF.MicrosoftSqlServer 软件包，因为您不能混合使用 beta8 和 rc1 组件
