title: Best free library in .NET to handle data in SQL Server?
body: <p>What is the best free library in .NET to :</p>
  
  <ul>
  <li>select, insert, update data in SQL Server with best performance (low level)</li>
  <li>launch stored procedure</li>
  <li>generate automatically object layer (1 object = 1 table) without relationnal link (foreign key is only id - 'int')</li>
  </ul>
  
  <p>I don't want to use EF (very bad performance)</p>
  
  <p>Thank you</p>
