The oracle provider for .NET OracleConnection and OledbConnection

Dear All:

Hi, I install a oracle 11g server, and I find use .NET OracleConnection connect to server success, but use OledbConnection fail. I check the oracle server,

it say that "OLE DB" intall fail, so I install oracle 11g client, and use OledbConnection connect to server success.

Does the .NET OracleConnection use "Oracle Data Provider for .NET 2.0 11.1.0.6.0" and .NET OledbConnection use "Oracle Provider for OLE DB 11.1.0.6.0"?

If I only install "Oracle Data Provider for .NET 2.0 11.1.0.6.0", can use .NET OledbConnection to connect to server?

Thanks.

Regards,
