Deployment from 11g to 10g connection string cannot get provider error.

Question

Hi, I'm doing a deployment from oracle client 11g to 10g. Is this possible? there are yes and no answer I have try out from the forum. All did not workout with any of the configuration setup.
For development I am using VS2012, MVC 4. EF 4. Oracle 11g
The server is currently running Oracle 10g with Oracle.Dataaccess.dll 10.2.0.100
This is my connection string setup at the server.
