How to add an assembly reference in the web.config file?

Below is a generic example on how to add an assembly reference in the web.config file.

            <add assembly="<AssemblyName>, Version=<Version>, Culture=<Culture>, PublicKeyToken=<PublicKeyToken>"/>

NOTE: You will need to insert the correct AssemblyName, Version, Culture, and PublicKeyToken for the required assembly in your web.config.  All managed .NET components will have a KB article with the components assembly information.
