20. Crear un Mobile Service
MobileService = new MobileServiceClient(
"https://myapp.azurewebsites.net");

21. Crear tablas (online)
IMobileServiceTable<TodoItem> table;
public async Task Init()
{
table = MobileService.GetTable<TodoItem>();
}

22. Crear tablas (offline)
IMobileServiceSyncTable<TodoItem> syncTable;
public async Task Init()
{
const string path = "syncstore.db";
var db = new MobileServiceSQLiteStore(path);
db.DefineTable<TodoItem>();
}
var handler = new MobileServicesSyncHandler();
await MobileService.SyncContext.InitializeAsync(db);
syncTable = MobileService.GetSyncTable<TodoItem>();

23. Push y pull con 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();
}

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