title: Oracle.DataAccess not available for selection in Visual Studio 2013
body: <p>I've recently set up a Windows 8.1 64 Bit Machine with Visual Studio 2013 (probably 32 bit, at least it installed itself at Program Files (x86)). 
  I've also installed the Oracle 11.2.0.1 64 Bit Client with Oracle Data Provider for .NET.</p>
  
  <p>When I do gacutil /l | findstr Oracle.DataAccess, I get four entries, including the following:</p>
  
  <pre><code>Oracle.DataAccess, Version=2.112.1.0, ..., processorArchitecture=AMD64
  </code></pre>
  
  <p>However, I cannot find Oracle.DataAccess in any of the lists when trying to add an assembly (Oracle.Web is present under Assemblies->Extensions, though).</p>
  
  <p>Do I have to install the 32 bit Oracle Client (or simply 32 bit ODP.NET) as Visual Studio is 32 bit? If so, will the software be able to run on a 64 bit system with a 64 bit application and 64 bit Oracle Client (with 64 bit ODP.NET)?</p>
