I apologize in advance for the long post. I've been working on a fairly simple ASP.NET MVC 5 site (Simple CRUD) using EF 5.0 and Oracle's ODP.NET 4.112.4.0. I am using VS2013 on an 64 bit machine and it is to deploy to IIS 7.5 running on a Windows 2008 r2 Server. I set my build status to x86 as that is what is registered in the C:\Windows\Assembly on the target machine. I ensured that the version of Oracle.DataAccess.dll is also a 32 bit version and that it matches version number to what is registered on the target server. (You can tell I've been stumbling around this awhile.) When I build it, I can run it on my local machine's IIS Express installation with no problems. Every page renders, it looks fantastic, it all works as designed. If only I could leave it running on my dev machine and point the users to that....
When I deploy it over to the production server. I use Web Deploy and I copy over all of the files. The Oracle.DataAccess.dll is set to Copy Local="True" just to be safe. It builds and publishes correctly, but the site gives me the following error:
Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342'. This assembly was compiled for a different processor.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.184
I have the application in its own file and as its own site. The Application Pool is version 4.0.30319 and pipeline mode is Integrated. I've also enabled 32-bit applications on this pool. I've been researching in vain trying to determine what else I need to do to get this situated, so I'm coming here and to asp.net to see if someone else can help me see what I've been missing.
Cheers,
