Question

我使用VS 2013在c＃中开发了一个应用程序。我的Windows 7桌面上的EntityFramework 6.0，运行时版本v4.0.30319

我可以使用SSMS连接到localdb。当我输入sqllocaldb.exe info v11.0

时，我看到了这个

Name: v11.0
Version: 11.0.3000.0
State: Running

代码：

using (var test = new myDataContextEntities())
{

 var yy = from x in test.names select x;
 Console.WriteLine(yy.ToList().Count);
}

在app.config中

<connectionStrings>
    <add name="myDataContextEntities" connectionString="metadata=res://*/AnalysisModel.csdl|res://*/AnalysisModel.ssdl|res://*/AnalysisModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=(LocalDB)\\v11.0;initial catalog=Analysis;integrated security=True;Pooling=False;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
  </connectionStrings>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>

问题：基础提供程序在ConnectionString上失败

我检查了4.02是按照建议安装的。 How can I find out if .NET 4.02 is installed?

Answer 1

我认为在“provider connection string =”

之后你的字符无效

在Windows7上访问localdb
