Currently I am working on a Windows Desktop Application made in WPF and .NET Core 3.0. Recently my client asked me to implement push notifications in my Desktop Application. The scenario is if there are multiple users that are working on the application on different computers.. for our example lets assume 2 users working on 4 systems (each user logged in to 2 computers) and suppose User1 had done some operation on his system so I want that a push notification should go to User1 logged in on another Computer. Also, User2 should not receive any notification for obvious as operation is performed by User 1. I am not sure how to achieve this functionality in WPF based desktop application. Can some one help here?
