Error: Could not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=9.0.0.0

I am getting this error that is related to ReportsViewer. I need to eliminate all references to this library. So where do I need to start deleting the references?

I had a similar issue. Look at your page directives and the bin directory for a Report file. Then look in your web.config. Your app should compile fine after that.
