Nao entendi pq pelo que vejo vc pode setar de 2 formas:
PRIMEIRA
<entityFramework>
 <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
 <parameters>
 <parameter value="Data Source=(localdb)\v11.0; Integrated Security=True; MultipleActiveResultSets=True" />
 </parameters>
 </defaultConnectionFactory>
</entityFramework>
SEGUNDA
<connectionStrings>
 <add name="BlogContext" 
        connectionString="metadata=res://*/BlogModel.csdl|
res://*/BlogModel.ssdl|
res://*/BlogModel.msl;
provider=System.Data.SqlClient;
provider connection string=
&quot;data source=.\SQLEXPRESS;
