C # assembly redirection

Question

I use Oracle.DataAccess and need access to the old database, which means that I need to use a slightly older version of this assembly. Both new and old builds are in the GAC, but I cannot force the application to use an older version. Here is my .config file:

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Oracle.DataAccess" publicKeyToken="89b483f429c47342"/>
        <bindingRedirect oldVersion="2.121.1.0" newVersion="2.112.3.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

fuslogvw shows nothing (like nothing, completely empty), but I'm not too familiar with this tool, so maybe I am using it incorrectly (too).

Any ideas?
