Computer changed names and AD. Can not debug app because ReportViewer can not be loaded

Question

My computer was recently renamed and put into a new domain. I can not longer debug my application because the ReportViewer assemblies can not be loaded.

"Could not load file or assembly 'Microsoft.ReportViewer.Design-<ComputerName>' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

This was working fine beforehand. I tried uninstalling and reinstalling ReportViewer using NuGet as well as Clean and force rebuild.

Not sure what else to try so any suggestions would be helpful. Thank you

Answer 1

I found that my Bin directory in my web project had duplicate files that were appended with my computer name. Removing them corrected the issue.
