This sample application has gone from showing you the initial architecture of the application, to using a business object as the basis for the report. The intent was to give you a flavor for the different tools available to you in Visual Studio 2005 for Crystal Reports.
In my opinion, there's a lot to be excited about concerning the new viewer for Crystal, and the new options VS 2005 provides for accessing data. Now that this is in Beta 2, feel free to try this and other new features! Keep on coding.
