  </configSections>
  <dataConfiguration defaultDatabase="MRS" />
  <connectionStrings>
    <add name="MRS" connectionString="Data Source=VU-39305EF5F3B7\SQLEXPRESS;Initial Catalog=MRS;Integrated Security=True;"
        providerName="System.Data.SqlClient" />
  </connectionStrings>
</configuration>

Well, not as much as your question is... What I'm telling you is to google for your error and try to understand what's going on, you know, what you should always do before posting any question.
