how do I get entity framework to work with oracle DB

I am not able to create an edmx with an oracle database connection. Here is what I have installed on my solution
1. ODP.Net Managed Driver
2. ODP.Net Entity Framework Managed Driver

Don't know what i am missing. Never used oracle db before so please help.

Here is my app.config
