This document discusses how to build connected mobile apps using Microsoft Azure. It provides an overview of Azure services for mobile backends such as REST APIs, offline sync, push notifications, and authentication. It also provides code samples for creating a mobile backend, defining and syncing tables, and querying local data. The document promotes Xamarin for building native and cross-platform mobile apps with shared C# code and recommends resources for getting started with Xamarin on Azure.

16. Create a Mobile Service
MobileService = new MobileServiceClient(
"https://myapp.azurewebsites.net");

17. Create tables
IMobileServiceSyncTable<TodoItem> syncTable;
public async Task Init()
{
const string path = "syncstore.db";
var db = new MobileServiceSQLiteStore(path);
db.DefineTable<TodoItem>();
}
await MobileService.SyncContext.InitializeAsync(db);
syncTable = MobileService.GetSyncTable<TodoItem>();

18. Push and pull with sync table
private async Task SyncAsync()
{
await MobileService.SyncContext.PushAsync();
var query = syncTable.CreateQuery();
await syncTable.PullAsync("todoItems", query);
}
private async Task InsertTodoItem(TodoItem todoItem)
{
await syncTable.InsertAsync(todoItem);
await MobileService.SyncContext.PushAsync();
}

19. Query local table
public async Task<IEnumerable<TodoItem>> GetOpenItemsAsync()
{
return await todoTable
.Where(item => item.Complete == false)
.ToEnumerableAsync();
}

22. 2. Store PNS handle

23. Notification Hub
• Maps between tags and handles
1. Get PNS handle
4. Send to device
2. Store PNS handle 3b. Request notification
Use device handles
3a. Request notification
Use logical users/tags
5. Manage device handles
