or her phone.

5. Only 1/4 are used daily:

6. 1/4 of apps are never used!

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

18. Create Tables
IMobileServiceSyncTable<Store> table;
public async Task Init()
{
const string path = "syncstore.db";
var db = new MobileServiceSQLiteStore(path);
db.DefineTable<Store>();
}
var handler = new MobileServiceSyncHandler();
await MobileService.SyncContext.InitializeAsync(db, h);
table = MobileService.GetSyncTable<Store>();

19. Get and Modify Data
public async Task<IEnumerable<Store>> GetStoresAsync()
{
await table.PullAsync("allStores", table.CreateQuery());
return await table.ToEnumerableAsync();
}
public async Task<Store> AddStoreAsync (Store store)
{
await table.InsertAsync (store);
await table.PullAsync("allStores", table.CreateQuery());
await MobileService.SyncContext.PushAsync();
return store;
}

20. Let’s add a backend

21. So Much More
