The new .NET SDK contains many nice improvements, including the ability to add line items. However, when adding multiple line items, the request fails when submitted to the gateway. This is because each line item is meant to be transmitted in a separate x_line_item field. However, when the SDK queues the line items, it simply concatenates all of the line item strings and submits them in a single x_line_item field.
