ADO.NET in a Nutshell

Oracle also provides its own native provider called ODP.NET (see Table A-8). It can connect to an Oracle 8 i or later database and be downloaded from http://otn.oracle.com/tech/ windows /odpnet with documentation and code samples. The ODP.NET provider provides the standard connection-based and type-specific classes, and is actually quite similar in structure to the Microsoft provider for Oracle.

To use the ODP.NET types, add the reference to the Oracle.DataAccess.dll assembly in your Visual Studio .NET project, or use the following command line when compiling:

csc /r:Oracle.DataAccess.dll codeFile.cs
