I am developing an single page web application that uses the Oracle.DataAccess dll. When I run the application locally I have to use the 32-bit version for IIS express. When I publish my application, IIS requires that I use the 64-bit version.

I was wondering if there was a way to change which version was included in the references depending if I run it locally vs. publishing it without having to manually change the dll each time before building.

I am currently developing in Visual Studio 2013 Update 3.

Do you use a separate build configuration when deploying vs running locally? If so, you can use the Condition attribute of a Reference to conditionally evaluate it based on the current build configuration like so:

<Reference Include="32 bit Oracle.DataAccess" Condition="'$(Configuration)' == 'LocalBuild'" />
<Reference Include="64 bit Oracle.DataAccess" Condition="'$(Configuration)' == 'MyDeploymentBuild'" />

You can install both x64 and x86 Oracle version on one machine, see here: Install both x86 (32-bit) and x64 Oracle Clients on your machine. Then you can compile your application in either ways without any changes. Just copy the correct version of Oracle.DataAccess.dll to your target system.
