I have a Silverlight application that uses Telerik reporting. I added the necessary references in my Web app, added a ReportService.svc file and the web.config service model xml. I added the Telerik references in my Silverlight app, and can add a ReportViewer in Visual studio's Designer. However, when I run the application I get an exception reading "The invocation of the constructor on the type 'MyProject.Report' that matches the specified binding constraints threw an exception." I have nothing entered for "ReportServiceURI" or "Report". Not sure what the issue is as it seems to load fine in the design view. Thanks in advance!
