LoadRunner .NET project (C#) that opens connections to Oracle DB and insert data or reading data

Hi,

I have a .NET project in LoadRunner that connect to SQL Server with SqlConnection oject and uses as well SqlDataAdapter/bulkCopy and other related sql methods. I used "using" of System.Data.SqlClient to achieve all the above.

Now, I want to transform the same project to work with Oracle. I found the relvant object through seeking the internet/MSDN e.g. OracleConnection, OracleDataAdapter but I'm failing to use it in LoadRunner (11), "using" of "System.Data.OracleClient" fails compilation.
