Hi, I just find out that latest provider works under Mono 3+ and Linux.
For working I have to copy System.Data.Entity.dll and System.ComponentModel.DataAnnotations.dll from Microsoft .NET 4 into my bin directory.
In this context is there are way to distribute a lighter version of ODP.NET without Entity Framework which not everyone is using until EntityFramework 6.0 support which is supported under Mono.
P.S. Any way now I can remove System.Data.OracleClient which is damn slow. Thanks.
System.ComponentModel.DataAnnotations.dll is needed because I took System.Data.Entity from Windows 8 / .net 4.5, When I took System.Data.Entity from .net 4.0 System.ComponentModel.DataAnnotations is not needed any more.
