Error when use VARRAY in Entity Model with VS2010

Question

Hi all,
At the database server, I created type is COUNTRY_LIST like:
CREATE OR REPLACE TYPE COUNTRY_LIST AS VARRAY (200) OF VARCHAR2(20);
And then created store procedure:
create or replace procedure get_all_country_data(vArrayResult OUT COUNTRY_LIST)
is
begin
SELECT country_name
BULK COLLECT INTO vArrayResult
FROM country
WHERE status = 1;
end;
On the VS2010, I created project with type Class Library (My goal is export to dll file) and I have been Entity Model technology to get data from Country table with above store procedure. I can connect to db, but after add Country model, I received some message from VS 2010:
The function 'GET_ALL_COUNTRY_DATA' has a parameter 'VARRAYRESULT' at parameter index 0 that has a data type 'varray' which is not supported. The function was excluded.     
Error 6005: The function 'GET_ALL_COUNTRY_DATA' has a parameter 'VARRAYRESULT' at parameter index 0 that has a data type 'varray' which is not supported. The function was excluded.
plz help me about it. Thanks.
