Access Report Viewer DLL Files for your Application

If an application requires the use of Report Viewer Redistributable and needs access to specific .dlls for the application to run, you’ll find this post helpful, http://drowningintechnicaldebt.com/blogs/dennisbottjer/archive/2006/10/16/Hacking-Report-Viewer-Redistributable.aspx.

It explains how to extract the necessary .dll files so you can reference them in your application and avoid GAC security errors (e.g., Could not load file or assembly ‘Microsoft.ReportViewer.Common, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The module was expected to contain an assembly manifest.)

I will outline the steps below to avoid another click. 😉 I have also added links for the most recent versions of Report Viewer.
