Updating the order processor

We can update the order processor worker role to call the Notification/PostOrderUpdate action when an order status changes. We'll do this in the following short procedure:

1. Install the mobile service NuGet package with the following command in the NuGet Package Manager Console:

   Install-Package WindowsAzure.MobileServices
   

2. Add a mobileServiceUrl string setting to the role's settings with the URL of our local service for local and the publish service for the cloud.
3. Add a mobileServiceKey string setting to the role's settings with the master key of our local service for local and the published service for the cloud.
4. Add a MobileServiceClient variable, which is instantiated in the constructor with cloud configurations settings like this:

   private readonly MobileServiceClient _mobileService;
   
   public OrderProcessor()
   {
       var mobileServiceUrl = CloudConfigurationManager.GetSetting("mobileServiceUrl");
       var mobileServiceKey = CloudConfigurationManager...
