To Reproduce

Add a template to MSNotificationHub

Code Snippet

// Set the delegate for receiving messages
MSNotificationHub.SetDelegate(new NotificationDelegate());

// Start the API
MSNotificationHub.Start(Constants.ListenConnectionString, Constants.NotificationHubName

public static string APNTemplateBody = @"{
                                            ""aps"":  { 
                                                ""content-available"":1, 
                                                ""messageParam"" : ""$(messageParam)""
                                                    }
                                                }";

var body = Constants.APNTemplateBody;
        var template = new MSInstallationTemplate();
        template.Body = body;
       


        MSNotificationHub.SetTemplate(template, key: "template1");

Expected behavior

When i send a notification matching the template, it is received by the app.
