Agenda• Cloud? What is that all about? We’re all in .. but in what?• Building a Windows Phone app that connects to NAV using the cloud.

Cloud computing? Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources(e.g., networks, servers, storage, applications, services) that canbe rapidly provisioned and released with minimal management effort or service provider interaction.

SERVICE ORDERS

Components in play• NAV – Service Dispatchers RoleCenter – Customizations – Web Services, .net interop• Proxy – C# Windows Service – Connecting to NAV Web Services – Exposing API on the Service Bus• Windows Phone 7 – Silverlight Application• Cloud – Windows Azure Account

Components - flow Windows Azure Firewall Storage Services Services Service Bus Proxy NAV Service Tier

SERVICE ORDERS – DEMO?

NAV customizations• Service Order card – On Creating/Modifying Service Orders • Send notifications (.net interop) – Related Information – Images • Download images from Azure storage • Service Order Image table• Exposes Web Services – For the Proxy • Customer Card Page • Service Order Card Page NAV Service • Special build Codeunit Tier

Windows Phone 7 Application• Connecting to NAV Web Services – Via the Service Bus • Get Service Orders • Accept Service Order • Change status on Service Order • Attach images and notes to service orders • Register notification channel (plumbing)• Connecting to Azure Storage – To storage images

Windows Phone 7• Free Developer tools – http://create.msdn.com/en-US/ – .net, C#, Silverlight – Microsoft• A TON of stuff on how to develop applications for Windows Phone already out there

Https Web Services Proxy - API[ServiceContract]public interface IServiceOrderProxyClass{ [OperationContract] ServiceOrder[] GetServiceOrders(string username, string password); [OperationContract] bool AcceptServiceOrder(string username, string password, string no); [OperationContract] void ChangeServiceOrderStatus(string username, string password, string no, stringstatus); [OperationContract] void AttachServiceOrderImage(string username, string password, string no, stringblobName); [OperationContract] void AttachServiceOrderNote(string username, string password, string no, string note); [OperationContract] void RegisterWp7ChannelUri(string username, string password, string channelUri);}

Https Web Services Proxy• Exposes endpoint on the Service Bus• Connects to NAV Web Services• Dedicated for Service Orders scenario• Only expose necessary API – Isolating NAV from attacks• Removes complexity• Reduces roundtrips• Loose coupling (device / NAV) – Possible to use other devices

Windows Azure Account• Windows Azure AppFabric (Service Bus) – For communication between phone and on-premise NAV • IssuerName, IssuerSecret• Windows Azure Storage – For image storing / retrieving • AccountName, AccessKey
