I have a click-once application. The output of this application is a file (with custom extension. for example .xyz). Auto-update facility is available only when I access this application thru the shortcut in the desktop. But when I access the application thru the output file (or the exe of the application in the local folder), auto update is not working. I know that the desktop shortcut is a .appref-ms file which access server first. 
Please let me know any options available to get this auto update feature even from the exe/output file. 

Thanks in advance...
