How to check if user has installed specific app on the WP8 device

Question

I\'m developing an app for WP8. Can I check (programmaticaly) if wp8 device has some specific app installed (i.e. WP8 Facebook app)?

Answer 1

You cannot get the list of applications that are installed on the Windows Phone that are published by someone other than the publisher of the calling application.

There is a way, however, to get the list of applications that are installed on the device and are originating from the publisher of the caller app. Here is what I am talking about:

IEnumerable<Package> apps = Windows.Phone.Management.Deployment.InstallationManager.FindPackagesForCurrentPublisher();
apps.First().Launch(string.Empty);

This required your app to run on a Windows Phone 8 device.
