Hi Happy new year with little delay.
Original the plan was to have a finally release for managed provider at the end of 2012, but there was a delay in the beta release that's why I want to ask when We can expect the final version?
In February or March ?
There will be another beta very soon, which will include bug fixes and integration with Oracle Developer Tools and EF DB First tools. That will be the last beta for managed provider. The production version will be packaged with the Oracle DB 12c on Windows release. A new ODAC release will follow that with a preset xcopy option.
Due to Oracle policies, I can't give provide any product release dates more specific than CY 2013, which is not very helpful due to how close to release Oracle really is. That's the best I can do for you with regards to a date at this time.
