Далее застронгнеймил сборку и опубликовал. В Dynamics CRM создаю бизнес-процесс. Объект - ЗАКАЗ. В ServiceURL:http://[назва_сервера]/Reportserver/ReportService.asmx, ReportName:/Новая папка/Прайс-лист, MailRecipient:[имя получателя]. Опубликовал бизнес-процесс. На форме ЗАКАЗ появилась кнопка Выполнить бизнес-процесс, но e-mail не отсылается.
