I have been using Crystal Reports for 20 years of developing desktop applications. I really liked the ability to create just about any type of report I needed and the ability to keep the report definitions separate from the application. However, since it is COM based, .Net 6 forced me to look for an alternative. I am currently testing Telerik Reporting. Like Crystal Reports, it has a stand-alone designer (as well as a VS extension). Also, like Crystal Reports, it allows me to keep the report definitions separate from the application allowing me to simply distribute TRDP files when reports change. It does an OK job on converting your existing RPT files to TRDP format. The interface is not as user friendly as CR but I'm getting used to it.
