I didn't go down the road of getting new DLL's. We had a bunch of existing projects that work perfectly fine and it was only my new project that was giving me headache so I decided to try something else.

My project was using an internally developed Internal.dll that depended on Oracle.DataAccess.dll v4.112.3.0. For some reason, when publishing, Visual Studio always uploaded v4.121.0.0, even though it wasn't explicitly specified in any of the config files. That's why I was getting an error.

So what I did was:

1. Copied Internal.dll from one of the successfully running projects to my web site's /bin (just to be on the safe side).
2. Copied Oracle.DataAccess.dll from one of the successfully running projects to my web site's /bin.
3. Add Reference to both of them from my web site.
4. Finally Oracle.DataAccess reference showed up in myWebSite.csproj, but it showed the wrong version: v4.121.0.0 instead of v4.112.3.0.

5. I manually changed the reference in myWebSite.csproj, so it now read:

   
     False
     bin\Oracle.DataAccess.dll
