Hi, Manuel5,
Based on my understanding, what you want to do is when a referenced dll is changed, all related ClickOnce applications should update automatically, don't you?
However, in my point of view, if you only changed adllin a project, itwill not trigger the ClickOnce applications to be updated.In fact, whena ClickOnce client is starting up, it will check theApplication Manifest on server to see if a newversion is released. That means thatall the clientswill notstart to updateuntil you republish all the related applications. So the answer for your question is no.
Another practical workaround is you can code your own update method in your application and let it to check the new version dll regularly. But that could be a little complex.
Hope this helps,
Regards
