title: F# using a class instance's member functions
body: <p>I'm trying to create a connection to open a database over ODBC.  I cannot figure out how to execute an objects member functions. The code:</p>
  
  <pre><code>let DbConnection = new System.Data.Odbc.OdbcConnection()
  
  DbConnection.open
  </code></pre>
  
  <p>The errors I get are:   <code>Missing qualification after '.'</code> </p>
  
  <p>or sometimes:   <code>unexpected identifier in implementation file</code></p>
  
  <p>Does anybody know what is wrong with my syntax?</p>
