In developing mobile web backends you might need users to broadcast messages such as push notifications to single or all  mobile subscribers from the cloud using services like Firebase Cloud Messaging (FCM).

To begin, download the library from Nuget:
    Install-Package Firebase.Notification -Version 1.0.0 

Using the library:
    using (var firebase = new Firebase()) 
        firebase.ServerKey = "{Your Server Key}"; 
        var id = "{Your Device Id}";
