Oracle Data Provider for .NET
Oracle Data Provider for .NET (ODP.NET) features optimized ADO.NET data access to the Oracle database. ODP.NET allows developers to take advantage of advanced Oracle database functionality, including Real Application Clusters, self-tuning statement cache, Application Continuity, and Fast Connection Failover. Developers can also use popular .NET features, such as Entity Framework Core.
There are three driver types: ODP.NET Core; ODP.NET, Managed Driver; and ODP.NET, Unmanaged Driver. ODP.NET Core is designed for multi-platform .NET (Core) applications. ODP.NET, Managed Driver is 100% managed code .NET Framework provider. Developers deploy a single assembly in a deployment package smaller than 10 MB. ODP.NET, Unmanaged Driver is the traditional Oracle ADO.NET provider that uses the Oracle Database Client.
ODP.NET 21c add support for user-defined types, .NET 6, Entity Framework Core 6, binary JSON data type, Client Initiated Continuous Query Notification, and more.
