Using Implicit REF Cursor in Oracle DB 12c

Question

For those interested in using ODP.NET implicit REF Cursors in Oracle DB 12c, the syntax is different from what was available in Oracle 11g. Here's a 12c-specific example:
=======================
Create or Replace PROCEDURE GetEmpAndDept
AS
EMPS  sys_refcursor;
DEPTS  sys_refcursor;
BEGIN
  OPEN EMPS for SELECT empno, ename from emp;
  dbms_sql.return_result(EMPS);
  OPEN DEPTS for SELECT deptno, dname from dept;
  dbms_sql.return_result(DEPTS);
END;
=======================
// C#
OracleConnection conn = new OracleConnection("User Id=scott; Password=tiger);
  conn.Open(); // Open the connection to the database
// Create the command object for executing cmdTxt
  OracleCommand cmd = new OracleCommand("GetEmpAndDept", conn);
  cmd.CommandType = CommandType.StoredProcedure;
  OracleDataReader rdr = cmd.ExecuteReader();
  while(rdr.Read())
     Console.WriteLine("{0}\t{1}", rdr.GetInt32(0), rdr.GetString(1) );
  rdr.NextResult();
   while(rdr.Read())
       Console.WriteLine("{0}\t{1}", rdr.GetInt32(0), rdr.GetString(1) );

i am using Oracle.ManagedDataAccess.dll v4.121.1.0
Oracle Data Base 12c
Visual Studio 2012 .net framework 4
But if I use Unmanaged Dll I get implicit results in my .net application.
