In case you don't know it already, Oracle has released ODP.NET which supports Entity Framework. It doesn't support code first yet though.

Answer 7

The answer is "mostly".

We've hit a problem using it where the EF generates code that uses the CROSS and OUTER APPLY operators. This link shows that MS knows its a problem with SQL Server previous to 2005 however, they forget to mention that these operators are not supported by Oracle either.
