Oracle Autonomous Transaction Processing supports connectivity to the Microsoft .NET Framework and Visual Studio.
Oracle Data Provider for .NET, Unmanaged Driver and Oracle Data Provider for .NET, Managed Driver provide run-time ADO.NET data access to the database service. Oracle Developer Tools for Visual Studio support design-time support for the database service. Oracle Providers for ASP.NET can store web application state using the service.
These software components are bundled together in a single software installation called Oracle Data Access Components (ODAC) for Windows and are available as a free download.
Oracle recommends using the latest ODAC version with Autonomous Transaction Processing.
