Hi Patrick,
Thanks for contacting Syncfusion Support.
Currently we don’t have same version assembly for combining ReportViewer and Dashboard control. So, we have considered to provide same version assemblies and for that we already logged feature request for “Combine Dashboard and Report Server into one”. This feature will be available in any of our upcoming ReportServer release.
Disclaimer: Feature implementation is tentative and not a commitment on our parts.
Regards,
Yuvaraj D.
