あなたはMSDN: Entity Framework Config File Settings

例web.configファイルで設定について読むことができますかもしれない：

<?xml version="1.0"?> 
<configuration> 

    <configSections> 
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/> 
    </configSections> 

    <connectionStrings> 
    <add name="MyConnectionString" connectionString="Data Source=MySqlServerInstance;Initial Catalog=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient"/> 
    </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>

[IIExpress] [1]

I believe since .netFramework4 IIExpress has been the default Db. 
Prior to that I believe localIS was. The Image below shows how to change 
to IIExpress if required. This tutorial will explain it better.
