I want to create a windows forms application which will run on client computer and will notify users when a new item added to a specific SharePoint list. Creating windows forms application or displaying notifications on this application is not really difficult but what is the best way to getting data from SharePoint list? It may be done by checking SharePoint list every 5 minutes for new items; but I do not want to do that. Can I broadcast data from SharePoint to trigger this application to notify users? Is there any other ways to do this?
Thanks in advance.
