.尝试过各种不同的解决方案
>在appconfig中废弃版本
>添加<dependentAssembly>
>使用Update-Package再次重新安装EntityFramework 6
-reinstall EntityFramework
>检查EntityFramwork.SqlServer
>已清除%temp%,并进行了清理构建以及独立重建
我在这里得到错误
[DbConfigurationType(typeof(CodeConfig))] public class MyContext : DbContext { public MyContext() : base("DefaultConnection") <-- error here { } }
但仍无法解决此错误,任何有用的链接将不胜感激

Web.Config中
<?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework.SqlServer, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </configSections> <connectionStrings> <add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="...." /> </connectionStrings> <entityFramework> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"> <parameters> <parameter value="mssqllocaldb" /> </parameters> </defaultConnectionFactory> <providers> <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> </providers> </entityFramework> </configuration>
首先检查您正在使用的EF版本.检查你的版本.
如果要升级版本,可以从NuGet管理EF升级.
转到您的项目解决方案 – > “管理解决方案的NuGet数据包”,单击“实体框架”上的“管理”.
现在,检查你的app.config.也许这里错误的版本号. name =“entityFramework”应具有正确的版本号.
除此之外,您应该尝试使用包管理器控制台中的以下命令为EntityFramework.SqlServer安装nuget包.
Install-Package EntityFramework.SqlServer -Version 7.0.0-beta6 -Pre
