EF provider for Oracle

I'd like to know if there are any good EF providers for Oracle out there, and more specifically what experiences people have had with them. We're looking for a provider that is either free or paid for, but I'm struggling a bit with finding any real opinions on wha开发者_运维问答t the different frameworks are like to work with in a production environment.

Thanks in advance.

EDIT I should clarify that we are using Oracle 11g.

Some light... Oracle has released a beta version of EF. Download it from http://www.oracle.com/technetwork/topics/dotnet/downloads/oracleefbeta-302521.html

Devart has a decent offer in this domain
