Your app simply isn't going to run in the background, unless you use background tasks, and then your app will need to be brought to the foreground to execute. It sounds like you're trying to recreate Skype, and I don't think that you're going to be able
to do that without having access to restricted APIs.

If my reply answers your question, please mark this post as answered.
NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined
objects and unknown namespaces.
