Make sure you have installed Visual Studio 2008 Service Park 1 Release (not Beta), OraDirect .NET 4.75.

You can find OraDirect .NET version here:
VS 2008, Menu Tools | Oracle | About OraDirect .NET

If the problem persists, please describe it.

As I understand you have the latest version (4.75.41) of OraDirect .NET. "ORA-03313:end-of-file on communication channel" error can be caused by different reasons.
Tell us please, when exception arises: after you click "Next" in Entity Framework wizard immediately or after delay.
Try to check arising this exception on the other Oracle sever with simple schema.

The latest build of OraDirect .NET version 4.75.42 is available. Its performance is much better when working with large schemas.
You can download it from http://www.devart.com/oranet/download.html or from Registered Users' Area (for the Subscription program members only).
