The name 'ParameterDirection' does not exist in the current context using Oracle.ManagedDataAccess.Client;

I am testing to get the id of an inserted row with dotnet with the package on the title (Oracle.ManagedDataAccess.Client) but when I try to specify the Parameter Direction the class is not recognized and get the error The name ‘ParameterDirection’ does not exist in the current context. I am using .NET 3.1
I am trying to specify it like this:

cmd.Parameters.Add(new OracleParameter(":id", OracleDbType.Int32, ParameterDirection.output));

Does the package not include the class ParameterDirection? Do I need another one?
Thanks.

Method 1

The ParameterDirection enumerator is available under the System.Data namespace. Please, make sure you are using this namespace.

using System.Data;
using Oracle.ManagedDataAccess.Client;

And try

cmd.Parameters.Add(new OracleParameter(":id", 
                                       OracleDbType.Int32, 
                                       ParameterDirection.Output));
