Also XPM functionality is working. However, if there are modifications on the Page or any Components on the Page that are not published, the "Update Preview" button will flash in the XPM GUI. Pressing this button will eventually end up in an error and the Update Preview button will keep flashing. This is due to the fact that we have not configured Session Preview yet.

XPM Configuration Switch In you web application's web.config , add the following line inside the configuration / appSettings node: <add key= "DD4T.IsPreview" value= "true" /> Only if this switch is present and set to true, the XPM markup will be generated in your HTML sources. Models Ready for XPM In order for XPM utility methods provided by DD4T out of the box to work, the models must: implement interface  DD4T.Core.Contracts.ViewModels.IViewModel ; annotate their Tridion fields with attributes; The code below shows a simple model that is XPM ready: using DD4T.ContentModel ; using DD4T.Core.Contracts.ViewModels ; using DD4T.Mvc.ViewModels.Attributes ; using DD4T....
