The type 'Microsoft.Reporting.WebForms.ReportViewer' exists in both

Question

I have a ASP.NET application which was referring Microsoft.ReportViewer.WebForms of version 9.0.0.0, I changed to refer to Microsoft.ReportViewer.WebForms of version 11.0.0.

Answer 1

My solution. I had old version of ReportViewer in _bin_deployableAssemblies folder. I deleted all from this, and use references from 'packages\Microsoft.ReportViewer.11.0.3366.16\lib' folder.
