I have built a rdlc report in VS 2013, which works fine in development, but once I attempted to deploy to the Windows 2003 Production box, I ran across the dreaded "Could
not load file or assembly 'Microsoft.ReportViewer.WebForms, Version=11.0.0.0,"
I have done a fair bit of investigation on this issue, but just require confirmation of my conclusion.
1. The ReportViewer control passes off requests for database access to the datasources you have specified while building the report, therefore
2. You don't also need to install a full blown version of SQL Server or SQL Server Reporting services on your web server.
3. If you install the Microsoft Report Viewer 2012 Runtime distributable on your webserver, it will install all the necessary dll's to the GAC and the problem is solved.
Thanks
