title: Toast notification isn't working?
body: <p>I'm following several examples to do a toast notification when I click a button in my app.
  I stepped through the following example: <a href="http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh868254.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh868254.aspx</a></p>
  
  <p>I'm not getting any errors but when I run the application I don't get the toast notification.
  I have created a snippet here: <a href="http://codepaste.net/btkzeg" rel="nofollow">http://codepaste.net/btkzeg</a></p>
  
  <pre><code>ToastTemplateType toastTemplate = ToastTemplateType.ToastImageAndText01;
  XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(toastTemplate);
  
  XmlNodeList toastTextElements = toastXml.GetElementsByTagName("text");
  toastTextElements[0].AppendChild(toastXml.CreateTextNode("Hello World!"));
  
  XmlNodeList toastImageAttributes = toastXml.GetElementsByTagName("image");
  
  ((XmlElement)toastImageAttributes[0]).SetAttribute("src", "ms-appx:///assets/oil.png");
  ((XmlElement)toastImageAttributes[0]).SetAttribute("alt", "oil graphic");
  
  IXmlNode toastNode = toastXml.SelectSingleNode("/toast");
  ((XmlElement)toastNode).SetAttribute("duration", "long");
  
  ((XmlElement)toastNode).SetAttribute("launch", "{\"type\":\"toast\",\"param1\":\"12345\",\"param2\":\"67890\"}");
  
  ToastNotification toast = new ToastNotification(toastXml);
  
  ToastNotificationManager.CreateToastNotifier().Show(toast);
  </code></pre>
  
  <p>If you have suggestions please let me know.</p>
