This is an update blog to my earlier blog about Sending Apple iOS Push notifications using C#.

With that blog – I  introduced you to  how to send push notification using Open Source library APNSharp, by the developer John Redth.  Redth announced that library is already deprecated.

Redth came up with  with another open source project called as PushSharp:,published under apache software foundation license.

PushSharp is a server-side library for sending Push Notifications to iOS (iPhone/iPad APNS), Android (C2DM and GCM – Google Cloud Message), Windows Phone, Windows 8, Amazon, Blackberry, and (soon) FirefoxOS devices!. Single library serves the purpose of sending push notifications to multiple platforms. Pretty decent isn’t it?

Here is the basic  architecture:

Features of PUsHSHARP

• Supports sending push notifications for many platforms:
  • Apple (APNS – iPhone, iPad, Mountain Lion)
  • Android (GCM/C2DM – Phones/Tablets)
  • Chrome (GCM)
  • Amazon (ADM – Amazon Device Messaging)
  • Windows Phone 7 / 7.5 / 8 (including FlipTile, CycleTile, and IconicTile Templates!)
  • Windows 8
  • Blackberry (BIS and BES via PAP)
  • Firefox OS (Coming soon)
• Fluent API for constructing Notifications for each platform
• Auto Scaling of notification channels (more workers/connections are added as demand increases, and scaled down as it decreases)

Implementation using PushSharp is straight forward

Here’s some sample code: shared by Redth

//Create our push services broker
var push = new PushBroker();

//Registering the Apple Service and sending an iOS Notification
var appleCert = File.ReadAllBytes("ApnsSandboxCert.p12"));
push.RegisterAppleService(new ApplePushChannelSettings(appleCert, "pwd"));
push.QueueNotification(new AppleNotification()
                           .ForDeviceToken("DEVICE TOKEN HERE")
                           .WithAlert("Hello World!")
                           .WithBadge(7)
                           .WithSound("sound.caf"));


//Registering the GCM Service and sending an Android Notification
push.RegisterGcmService(new GcmPushChannelSettings("theauthorizationtokenhere"));
//Fluent construction of an Android GCM Notification
//IMPORTANT: For Android you MUST use your own RegistrationId here that gets generated within your Android app itself!
push.QueueNotification(new GcmNotification().ForDeviceRegistrationId("DEVICE REGISTRATION ID HERE")
                      .WithJson("{"alert":"Hello World!","badge":7,"sound":"sound.caf"}"));
