Aspose.Words for .Net not working with VS 2010 and Report Viewer 10.0


we recently migrated the code from VS 2008 to VS 2010 and also updated the references for the Microsoft.ReportViewer from 9.0 to 10.0. And now we are getting a runtime exception as below:

"Unable to cast object of type ‘Aspose.Words.ReportingServices.DocxRenderer’ to type ‘Microsoft.ReportingServices.OnDemandReportRendering.IRenderingExtension’."

Can you please suggest if the Aspose.Words for .net has a working version for the VS 2010 and Report Viewer 10.0?



Thanks for your request. If I understand you correctly you are using Aspose.Words for Reporting Services. You can learn about system requirements of Aspose.Words for Reporting Services here:

Best regards,


thank you for the quick reply.

the system requirements does not show Microsoft Report Viewer 2010. Of course, so far when we were using VS 2008, we were also using Microsoft Report Viewer 2008 and hence the Aspose.Words worked for us.

But now, since we have migrated to
Microsoft Report Viewer 2010, we need to know if Aspose supports this version of report viewer. If so, can you please let us know which version of Aspose.Words supports Microsoft Report Viewer 2010?



Thanks for your request. Unfortunately, Aspose.Words does not support this version of Report Viewer. I linked your request to the appropriate issue. You will be notified as soon as it is resolved.
