title: .net connection pooling
body: <p>I don't get what is the syntax difference between regular connection and connection pool.</p>
  
  <p>When I'm using the <code>using</code> key such as:</p>
  
  <pre><code>using (SqlConnection connection = new SqlConnection(connectionString))
  {
      connection.Open();
      command.ExecuteNonQuery();
  }
  </code></pre>
  
  <p>Is this the way to perform a connection pool?</p>
