<%@ Register Assembly="Telerik.Sitefinity" Namespace="Telerik.Sitefinity.Web.UI" TagPrefix="sf" %>
And I changed the java script built action to embedded resource. However, it is still not working. I do not have an assembyinfo.cs and I don't have the sitefinity web application set up. Is there another way to do it or does someone know how to access/create the file without using sitefinity web application.
