System.Data.OracleClient.dll with .NET Framework 4.0
If you recall starting .NET 1.1 until .NET 3.5 all the .NET platform shipped with an assembly named System.Data.OracleClient.dll, which was one of the recommended data provider to connect .NET appplication with Oracle databas.seas the name suggests, offered a data provider to communicate with Oracle databases.
With the release of 4.0, Microsoft made this assembly obsolete and will eventually be deprecated.
The reason is certainly not that Microsoft only wants SQL Server and other MS specific Dbs to be used using .NET, but the actual reason is that Oracle corp provides its own custom .NET assembly, which follows the same overall design guidelines as the data providers provided by Microsoft.
You can download this assembly free of cost from Oracle corp's web site at
www.oracle.com/technology/tech/windows/odpnet/index.html.
