    ODAC 11.2 Release 4 and Visual Studio 2010SP1 Question

      A co-worker and I have been working on converting from SQL Server to Oracle 11g. Both of us have downloaded the 32-bit visual studio tools and installed them (http://www.oracle.com/technetwork/database/windows/downloads/index-101290.html). We've also downloaded and installed the ODAC 64-bit drivers (XCopy only - http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html). Both of us can build/run the solution (which is sync'd using a repository) and communicate with Oracle (i.e. we are able to query an Oracle table and display the results). However, I get this warning message in Visual Studio that my co-worker does not get. I was hoping someone has seen it before and knows of a solution. The warning message is: ASP.NET runtime error: Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format. We are running IIS7 in 64-bit mode. The message only appears for ASPX pages I have open. Also, we are using .NET4.0 framework on Windows 7 64-bit. The Oracle drivers seem to be in the GAC32 and GAC64 locations. Any ideas?
