title: Can I use 32 bit Oracle Developer Tools with x64 ODAC in VS2010?
body: <p>From the Oracle website here:
  <a href="http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html" rel="nofollow">http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html</a></p>
  
  <p>This is for their latest Oracle Data Access Components, 64-bit ODAC 11.2 Release 4 (11.2.0.3.0) for Windows x64.  I want to use the developer tools (ODT) but they aren't available in 64 bit (probably because VS2010 is still 32-bit).  From the site:</p>
  
  <p>Important: The 32-bit Oracle Developer Tools for Visual Studio download is required for Entity Framework design-time features. The above download fully supports Entity Framework deployment, but does not contain design-time tools. </p>
  
  <p>I don't use EF (I use the Mindscape LightSpeed product as it's usually 3 or 4 years ahead of EF) but the principle is the same - VS2010 and LightSpeed are 32-bit apps and can't load/use x64 libs.</p>
  
  <p>I would like to use the 32-bit tools (ODT) to develop my app and deploy the app using the x64 ODAC.  Has anyone done this?  Can it be done?  Anybody?</p>
  
  <p>If it matters, this is for a WCF service running on a virtual Windows Server 2008 R2 machine. What I have done semi-successfully is force everybody to 32-bit operation, but that seems a little silly if 64 bit is supported as they claim it is.</p>
  
  <p>Thanks in advance,
  Dave</p>
