hey i m generating a crystal report in vs 2010 using linq to sql in desktop apps.
But i m getting this error at the click event of the print button. 
 
Error:  DataSet does not support System.Nullable<>

as
begin
select cust.customer_name,item.item_name,inv.invoice_no,inv.Qty,inv.price,
inv.item_amount,inv.disc,inv.disc_amt,inv.vat,inv.vat_amt,inv.total_amt
from inv_invoice_detail as inv
inner join Inv_Customer_Name as cust
