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.

when i Clieck "Next" after delay pop-up "Execate data defineORA-03313: END-OF-FILE....." at EDM Wizard.
if use LINQ To Oracle Beta is fine!
but it need OraDirect.net Version:4.75.23.

i have Test in other Oracle Server arisen alike problem!
My OS:windows Server 2003 sp1(language Chinse)
Oracle 9.2
help me! thanks!

I have a serious problem:

-- Adding an item type ASO.Net Entity Model
-- Select or create a new connection to Oracle
-- Select tables for inclusion in the model
-- Completion
-- Remains hung system, I have to close because no response VS2008

Configuration:
-VS2008 SP1

I need to solve this problem in order to generate new projects using your provider.

Thanks,

The latest build of OraDirect .NET version 4.75.42 is available. Its performance is much better when working with large schemas.
