Adding Report Viewer Webpart through console app Throws UpdatePanel Error

Question

Hi,
    I had created a console application in Visual Studio 2012, to add Report Viewer Webpart into the team site page in sharepoint 2013. I wrote a code to add the Report Viewer webpart into the sharepoint site. I followed some links to successfully
execute the console application to add the Report Viewer webpart.
    After successful execution of the console application, if i navigate to the sharepoint site where i had added the webpart through console application, it throws the following error.
"Cannot unregister UpdatePanel with ID 'ViewerAreaUpdatePanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported".
    In my console application i didn't use any UpdatePanel. Just add the webpart into the default sitepage in sharepoint. Hope it was in the default page on the sharepoint site.
   I had googled the rootcause for the error, but i end up with all the answers pointing to ScriptManager into the aspx page. But i didn't find the SafeScriptManager .dll file. I followed the steps, in some other sites to create the ScriptManager
dll file, but that .cs project was not in compatible mode with VS 2012/2010.
I had attached the full executing code of the console application.

return webPart.ID;
catch (Exception exception)
throw new Exception("Unable to Add WebPart To Page: " + pageUrl + " Webpart title: " + webPart.Title + "Error: " + exception.Message);
   Could anyone have the solution to overcome the above issue. I was knocking my head to resolve this error.
 Note:
    I am using,
    1. sharepoint 2013
    2. SQLServer 2012R2
    3. Windows2008R2 server
 I can able to create the ReportViewer webpart in the site manually.
Thanks

Hi Jai,
Did you find a workaround to this issue. I have the exact same issue with SharePoint foundation 2010. I am adding report viewer webpart through HTML5 web page hosted in SharePoint site.
