Integrating PushSharp In the WCF Restful Web Service to display Push Notifications in Apple, Android and Windows devices

Hello Folks, Today I will demonstrate the method of integrating the PushSharp library in WCF Restful Web Service to send the Push Notifications to Apple, Android and Windows devices.


This library and its documentation is available on the GitHub at following link

Redth/PushSharp


Create a new WCF web service in the Visual Studio(Here I am using Visual Studio 2012). After creating the Web Service, Go to Tools-> NuGet Package Manager -> Manage NuGet Packages for Solution as shown in following image.




In the Package Manager, Search "PushSharp" 


After installing PushSharp NuGet Package, following dlls will be added in the bin folder of the solution. 




Next are the lines of the code which are used to send the notifications from the web service. Please consider following is the minimalist code required to send notifications to devices. For additional functionality, please go through the samples given in the GitHub library of PushSharp.

For Sending Push Notifications to the Android device.

 public void SendAdnoirdPush(string APIKey, string DeviceID, string Message)  
   {  
     var push = new PushBroker();  
     push.RegisterGcmService(new GcmPushChannelSettings(APIKey));  
     push.QueueNotification(new GcmNotification().ForDeviceRegistrationId(DeviceID)  
             .WithJson("{\"alert\":\"" + Message + "\",\"badge\":7,\"sound\":\"sound.caf\"}"));  
   }  

APIKey of the App can be obtained from the Google Developer Console.
DeviceId of the device using the App.
Message to be displayed in the Notification.


For Sending Push Notifications to the iOS device.

 public void SendiOSPush(string DeviceID, string Message, string sound)  
   {  
     var push = new PushBroker();  
     var appleCert = File.ReadAllBytes(new DirectoryInfo(HostingEnvironment.ApplicationPhysicalPath) + "/pushNotificatio.p12");  
     push.RegisterAppleService(new ApplePushChannelSettings(true, appleCert, "CertificatePassword"));  
     push.QueueNotification(new AppleNotification()  
                   .ForDeviceToken(DeviceID)  
                   .WithAlert(Message)  
                   .WithBadge(7)  
       .WithSound(sound));  
     //.WithSound("sound.caf")); //default  
   }  

DeviceId of the device using the App.
Message to be displayed in the Notification
sound to be played with Notification

For implementing the iOS Notifications, a signed certificate is required to be generated from the Developer Console. That certificate is copied in the system and Path is given as in the method above. 
Please be careful while mapping the path of the certificate. The certificate is different for sandbox and production
RegisterAppleService requires the certificate password. 

For Sending Push Notifications to the Windows phone.

 public void SendWindowsPhonePush(string ChannelUri, string pageName, string Header, string Message)  
   {  
     var push = new PushBroker();  
     push.RegisterWindowsPhoneService();  
     push.QueueNotification(new WindowsPhoneToastNotification()  
     .ForEndpointUri(new Uri(ChannelUri))  
     .ForOSVersion(WindowsPhoneDeviceOSVersion.Eight)  
     .WithBatchingInterval(BatchingInterval.Immediate)  
     .WithNavigatePath("/" + pageName)  
     .WithText1(Header)  
     .WithText2(Message));  
   }  

ChannelUri is the unique identifier for each device using the App
pageName to navigate to when notification is clicked
Header to be displayed in the Notification Header
Message to be displayed in the Notification Message


and voila!!!! DONE

Above methods can also be combined into one method to send notification to all types of devices., also If notifications are to be sent to multiple devices of same OS, then a "for" loop can be traversed as per the requirement for each method.

To update the .edmx file when the database changes

  1. In the Model Browser, right-click the .edmx file and select Update Model from Database.
  2. The Update Model Wizard starts. If there is no database connection specified, the Choose Your Database Connection dialog box appears. Otherwise, the Choose Your Database Objects dialog box appears. 
  3. If the Choose Your Database Connection dialog box appears, specify a database connection. Otherwise, go to the next step.
  4. For details about specifying a connection, see Choose Your Data Connection Dialog Box (Entity Data Model Wizard). When you have specified the connection, click Next to display the Choose Your Database Objects dialog box.
  5. Click the Add tab.
    Nodes for tables, views, and stored procedures are displayed. If any objects have been added to the database (or were not included in the previous storage model), you can expand the corresponding node to view the objects that are available to add to the conceptual model.
  6.  If an object has been deleted from the conceptual model but has not also been deleted from the storage model, the object will not be available to add to the conceptual model.
  7. Expand the Tables, Views, and Stored Procedures nodes, and check the objects you want to add to the .edmx file.
  8. Click the Refresh tab.
    Nodes for tables, views, and stored procedures that are included in the existing storage model are displayed. Any changes that have been made to these database objects will be reflected in the updated storage model. Changes to the conceptual model are made when columns are added to a table or view.
  9. Click the Delete tab.
    Nodes for tables, views, and stored procedures are displayed. If an object has been deleted from the database and was included in the previous storage model, you can expand the corresponding node. The objects in these nodes will be deleted from the updated model.
    Click Finish to update the .edmx file with the database changes.
