Using BusinessObjects Enterprise in C#/ASP.Net App

I am using VS 2010 and 4.0 framework and have create web browser app, which shows a page to the user after entering data and I want to print that page. I would like to use a Cryatal Report to show the page and be able to print. What I am trying to do is call BusinessObject Enterprise to run the Crystal report, but all the examples I am seeing is using BusinessObjects.ReportEngine which is appartently is not available in VS 2010. I am seeing BusinessObjects.DSWS but I do not have it. Is BusinessObjects.DSWS what I need to use to call BusinessOjbects ReportEngine and etc? If so, where can I download the complete BusinessObjects.DSWS ?
