Using the .NET Framework Data Provider for SQL Server
This section describes features and behaviors that are specific to the .NET Framework Data Provider for SQL Server.
The .NET Framework Data Provider for SQL Server provides access to a SQL Server version 7.0 or later database using its own internal protocol. The functionality of the data provider is designed to be similar to that of the .NET Framework data providers for OLE DB, ODBC, and Oracle.
To use the .NET Framework Data Provider for SQL Server, an application must reference the System.Data.SqlClient namespace.
