Not a valid month, but works from sql developer

Question

Hi,
so this sample works from SQL DEV. :
insert into aspa2_magaddendum (contractid, addendum_number, from_date, to_date) values(2, 0, '03.05.2012', '24.05.2012');
but not from code using ODP.NET
            string date1 = "03.05.2012";
            string date2 = "24.05.2012";
            OracleConnection conn = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521))(CONNECT_DATA=(SID=XE)));User Id=aspa2;Password=aspa2;");
            conn.Open();
            OracleCommand cmd = new OracleCommand();
            cmd.Connection = conn;
            cmd.Parameters.Add("date1", date1);
            cmd.Parameters.Add("date2", date2);
            cmd.CommandText = "insert into aspa2_magaddendum (contractid, addendum_number, from_date, to_date) values(2, 0, :date1, :date2)";
            cmd.ExecuteNonQuery();I get:
ORA-1843: not a valid month message from exception

Looks like SQL DEV. session is a bit different from the one in code...
From SQL DEV i get:
select value from nls_session_parameters where parameter = 'NLS_DATE_FORMAT';
"DD.MM.RR"
and from the code I get:
cmd.CommandText = "select value from nls_session_parameters where parameter = 'NLS_DATE_FORMAT'";
string format = cmd.ExecuteScalar().ToString();
"DD-MON-RR"
