Is there any way to realize communication between a Windows Universal App and a standard Desktop application running at the same computer? I read that UAs don't support IPC. Instead they use those so called background agents. But is it possible to use those background agents not to communicate with a UA but rather a desktop application or is this completely suppressed?
The reason is, that I already have a desktop application and I would like to add Cortana support to it, without too much effort. So I would like to avoid converting the desktop app to a universal app. Cortana is only available in Universal Apps at the moment.
