由实体框架自动创建的数据库的位置

Question

I have been using Entity framework recently and my WPF application totally works fine although i have a little problem. Despite it stores and retrieves data, i can not see or find the data base which has been created by the framework. When i start SqlServer management studio there is no new data base there. I also searched this path "C:\\Program Files\\Microsoft SQL Server\\MSSQL10_50.MSSQLSERVER\\MSSQL\\DATA" but i couldn't find it. Another odd thing is that i didn't put any connection string inside the config file but as i said, it stores data somewhere in an anonymous data base. Would you mind telling me where exactly the data base is ? I am using Microsoft Sql Server 2008R2.

<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>

Answer 1

Work with connection string in web.config.
Example:

Web.config

  <connectionStrings>
    <add name="AnyName" providerName="System.Data.SqlClient" connectionString="Data Source=(localdb);Initial Catalog=DbName;Integrated Security=True;MultipleActiveResultSets=True" />
  </connectionStrings>

In your context

public Context()
        : base("AnyName")
    {}

The name ( "AnyName" ) must be the same in context and connectionstring.

Hope it's useful!
