title: SharePoint Event Receiver
body: <p>I have written a simple code on VS 2015 to handle ItemAdded EventReceiver but it won't fire as expected. </p>
  
  <pre><code>public void ProcessOneWayEvent(SPRemoteEventProperties properties)
  {
    try
    {
      using (ClientContext clientContext = TokenHelper.CreateRemoteEventReceiverClientContext(properties))
      {
        if (clientContext != null)
        {
          switch (properties.EventType)
          {
            case (SPRemoteEventType.ItemAdded):
              clientContext.Load(clientContext.Web);
              clientContext.ExecuteQuery();
              List list = clientContext.Web.GetList("https://learn91.sharepoint.com/sites/Demo/Lists/List1");
              clientContext.Load(list);
              clientContext.ExecuteQuery();
              CamlQuery query = new CamlQuery();
              query.ViewXml = @"&lt;OrderBy&gt;&lt;FieldRef Name='ID' Ascending='FALSE'/&gt;&lt;/OrderBy&gt;";
              ListItemCollection items = list.GetItems(query);
              clientContext.Load(items);
              clientContext.ExecuteQuery();
              foreach (ListItem item in items)
              {
                  item["Description"] = "Updated After Event Trigger";
                  clientContext.Load(item);
                  clientContext.ExecuteQuery();
              }
              break;
          }
        }
      }
    }
    catch (Exception ex)

    }
