All the ODAC 12c downloads have managed ODP.NET. You can install only managed ODP.NET, but not the other components if you don't want the thick client.
If you just want to deal only with managed ODP.NET, you can download the software titled "ODP.NET_Managed121010.zip" on the page you link to.
What I want to use is the new connector where the only thing I need to install is that connector. So no Oracle client, no TNS, no ORA, etc.
Is that ODP.NET? Or is ODP.NET the older connector that requires the Oracle client also be installed?
