In SharePoint it is necessary for the referenced .dll's to be available in the GAC. By add the Ionic name space and the location of the .DLL referenced through the Package 9under the Advanced Tab), the .DLL is automatically included in the deployment and viola - no more errors.</p>\r\n<p>Thanks to those that took a stab at this for me!</p>\r\n<p>Greg</p>",
