Can you use Microsoft Entity Framework with Oracle?

Is it possible to use Microsoft Entity Framework with Oracle database?

Update:

Oracle now fully supports the Entity Framework. Oracle Data Provider for .NET Release 11.2.0.3 (ODAC 11.2) Release Notes: http://docs.oracle.com/cd/E20434_01/doc/win.112/e23174/whatsnew.htm#BGGJIEIC

More documentation on Linq to Entities and ADO.NET Entity Framework: http://docs.oracle.com/cd/E20434_01/doc/win.112/e23174/featLINQ.htm#CJACEDJG

Note: ODP.NET also supports Entity SQL.

DevArt's OraDirect provider now supports entity framework. See http://devart.com/news/2008/directs475.html

Oracle have announced a ["statement of direction"][1] for ODP.net and the Entity Framework:

In summary, ODP.Net beta around the end of 2010, production sometime in 2011.

Yes. See this step by step tutorial of Entity Framework, LINQ, and Model-First for the Oracle database (11G), and using Visual Studio 2010 with .NET 4.

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.

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.

Now has a new nuget package, try use it: https://www.nuget.org/packages/Oracle.ManagedDataAccess.EntityFramework/
