Jag såg iofs en gammal add-in från 2002 för Oracle och .Net men det kan vara bra att ha denna informationen i forumet om någon söker på det.

.NET Managed Provider for Oracle
The .NET Framework Data Provider for Oracle is an add-on component to the .NET Framework that provides access to the Oracle database. This provider relies upon Oracle Client Interfaces provided by the Oracle Client Software. Supported Operating Systems: Windows 2000, Windows 98, Windows ME, Windows NT, Windows XP

Important: If the .NET Framework (which is included as part of Visual Studio .NET) is not installed the setup for this download will fail. As part of the setup for this download the System.Data.OracleClient namespace is added to the global assembly cache.
