title: ora-06413 connection not open in visual studio 2010 (Server Explorer)
body: <p>I've been trying to open a connection to my Oracle database (x86) in visual studio 2010 (x64) from a Server Explorer tool.</p>
  
  <p>I get this error : </p>
  
  <blockquote>
    <p>ora-06413 connection not open</p>
  </blockquote>
  
  <p>The strange thing is that I can connect to the database from my C# code instead of using Server Explorer Tool.
  What Kind of problem could it be ?</p>
