title: Access Oracle database from Visual Studio 2008
body: <p>I need to be able to access Oracle database from Visual Studio 2008(Framework 3.0/3.5). The Database version is 11g.                               </p>
  
  <p>But I also may need to access older version of this database going back to the year 2007.
  I tired to install Oracle database client 11gR2 on my desktop computer which has Windows 7 Enterprise edition.<br>
  It did not run from Setup menu but ran from background it seems.
  Did notice a folder in C:/Oracle with 2 files sqlnet.ora and TnsNames.ora, but apart from that I noticed in the c:\windows\assembly there was no Oracle.DataAccess components installed.</p>
  
  <p>Which client or tools should I need to install to be able to access versions of Oracle from Visual Studio 2008?                    </p>
  
  <p>Assuming you suggest there is a client version for each of the Database versions, Can I install one client version on top of the other.</p>
  
  <p>Now that I have installed the client 11gR2 can you tell me if I need to install it, I do not see an uninstaller under my "All Programs" menu .</p>
