ExecuteNonQuery doesnt return number of rows affected when used with PL/SQL

Question

ExecuteNonQuery doesn't return number of rows affected when used with PL/SQL but returns -1. The documentation says ExecuteNonQuery method of OracleCommand returns the number of raws affected but when used with PL/SQL, it returns -1 even the update statement successfully executes and affects multiple records with no exeptions thrown.
However, if ExecuteNonQuery is used with update sql statement in the asp.net code it returns number of rows affected correctly. Does anybody know why ExecuteNonQuery behaves like this?
I am using ODP.NET that comes with Oracle Client 11g. The version is 2.111.6.20 of ODP.NET, Oracle database server is 10g.

You can get the rowcount in the stored procedure via SQL%ROWCOUNT and then pass it out as a parameter.
For example:
SQL> create or replace procedure updatesal(v_deptno in number, v_rowsaff out number) as
  2  begin
  3  update emp set sal = sal * 5 where deptno = v_deptno;
  4  v_rowsaff := SQL%ROWCOUNT;
  5  end;
  6  /
Procedure created.Cheers
