これをサーバーに公開すると機能しないため、接続文字列が間違っているかどうか疑問に思っています。それ以外の場合は、デバッグモードでテストすると機能します。
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-app-20130122205025;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-app-20130122205025.mdf"
providerName="System.Data.SqlClient" />
