Create a Mobile Service
MobileService = new MobileServiceClient(
public async Task Init()
const string path = "syncstore.db";
var db = new MobileServiceSQLiteStore(path);
var handler = new MobileServiceSyncHandler();
await MobileService.SyncContext.InitializeAsync(db, h);
table = MobileService.GetSyncTable<Store>();
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 ());
Sync files to Azure Storage, just like you did for structured data.
Nuestras apps necesitan un backend que les permita conectarse a cualquier tipo de datos, autenticar a nuestros usuarios con Directorio Activo o redes sociales como Facebook o Twitter, enviar notificaciones Push a cualquier tipo de dispositivo, y conectarse a sistemas empresariales como SAP, Sharepoint, y muchos más. Nuestras apps necesitan Azure App Services. Aunque Sheldon no estará de acuerdo, porque Azure App Services nos lo pone demasiado fácil para su gusto.

Although it is possible to use Sticky Sessions in Azure it’s not a great fit for cloud architecture, for these reasons:
1) When you provision new instances, only new sessions will be routed to them. Depending on your load balancing logic, new sessions may also still be provisioned on the old instances. This results in it taking a long time (depending on the average length of your session) for load to be evenly distributed across your instances.
2) Cloud solutions should be designed to fail. One of your instances may be removed at any time for patching, or hardware failure. With a sticky session scenario, the clients with a session on this instance will probably have to log in again, or may see an error page, depending on your load balancing logic.
3) Unless your load balancer shares state in some way, it’s likely that you’re load balancing with a single instance (single point of failure) and not eligible for the Microsoft SLA.
Detect issues, diagnose crashes and track usage in your mobile apps and web apps.
Azure > App Services > API Apps
Azure API Apps provide a rich platform and ecosystem for building, consuming, and distributing APIs in the cloud and on-premises.
Challenges Authoring APIs
Manual plumbing: Logging, auth/SSO, secret store, config, updating, versioning
Difficult to integrate to on-premises and SaaS investments
No governance or monitoring of API performance without separate APIM product
Monolithic designs complicating versioning, agility, and scale
Challenges Consuming APIs
Difficult for professional developers; impossible for business users
Inconsistent metadata and authentication story
Lack of organizationally-scoped galleries
Inconsistent (or lack) of API documentation
Benefits of API Apps
Bring your API as-is: .NET Web API, Node.js + Express, Java, PHP, Python.
Integrated Swagger metadata
Simple access control
Connect easily to SaaS platforms
Easy connectivity to Logic Apps
Built-in Visual Studio tooling/support
Marketplace support: Private API gallery (NuGet feed), Public Azure Marketplace.
Easily use cloud or custom APIs
Dozens of built-in APIs for popular SaaS
An ecosystem of APIs for any need
Create and publish custom, reusable APIs
Visual Studio tooling with one click publish and remote debugging
Automatic client SDK generation for many languages
Authoring API Apps
Package and Publish
Use WebDeploy like Web Apps
Use local Git repo
Publish to the Marketplace (coming soon)
Metadata about Web Service forms Contract
Done using Swagger 2.0 for your platform of choice
Metadata makes API “discoverable”
SSO or security aspects are handled at the server level, not the app
Easily build Microservices
Anyone can call the API app from outside the resource group without being logged in.
Only authenticated users are allowed to call the API app from outside the resource group.
Only other API apps in the same resource group are allowed to call the API app.
Public (Authenticated) Access Level
API App Access
-> Azure Active Directory
-> Microsoft Account
-> Social Identities: Facebook, Google, Twitter.
Consuming API Apps
API Apps expose HTTP services
Metadata is exposed using Swagger 2.0 metadata
Engine that provides a JSON representation of your API for integration with various frameworks, applications and tools.
Swagger metadata is a description of the capabilities of your API application.
Through dynamic metadata you can generate:
Integrates into many services and frameworks including
Already supported in the API Management service
Already supported in many tools:
Postman, Runscope, SoapUI
Automatically generated User Interface to view metadata and documentation for each service endpoint.
The Azure Preview Portal can visualize your API for you. You can also download the JSON Swagger metadata directly from the portal.
API App Templates
App Templates are available today to connect to your favorite SaaS services.
Languages, tools, and SDKs
Anything supported by Azure App Services
.NET, Java, PHP, Python, Node, … and yes, even Go!

Logic apps for orchestration across API apps
1. Implicitly – whenever you reference the output of an action you’ll depend on that action executing first
2. Explicit “dependsOn” condition – you can mark certain actions to run only after previous ones have completed
3. Explicit “expression” condition – a complex function that evaluates properties of other actions
Loop a single action over a list of items
Runs the action N times
You can get at all of the statuses for each action
Logic on a trigger or action
For triggers conditionals are post-conditions
For actions conditionals are pre-conditions
You can do conditionals inside of repeats to perform as a filter

App Service API Apps - What's changed
The Logic Apps designer will be adding especially seamless integration with the new API Apps model in early 2016. That said, the HTTP connector built into Logic Apps can invoke any HTTP endpoint and supports service principal authentication, which is also supported natively by the App Service authentication services. Learn how to consume an App Service-hosted API in Logic Apps in Using your custom API hosted on App Service with Logic apps.

Why use mobile offline sync?
Improve app responsiveness by caching server data locally on the device
Make apps resilient against intermittent network connectivity
Allow end-users to create and modify data even when there is no network access
Sync data across multiple devices
Detect and handle conflicts when the same record is modified by more than one client
How offline sync works
Access data from Mobile Services tables even when app is offline
Keep a local queue of Create, Update, Delete operations and synchronize with server when app is back online
Detect conflicts when same item is changed both locally and on server
Use soft delete to remove deleted records from client data stores
Can use push notifications to trigger client sync
Azure Mobile offline sync
Lightweight and composable. Eliminates burdens of database-to-database sync
Works with a variety of server data stores. SQL, Azure Tables, Mongo, Dynamics CRM, Salesforce, etc.
Cross-platform client SDKs. Windows Universal, Xamarin, iOS, Android
Supports both “primarily online” and “occasionally connected” scenarios. Explicit push and pull leaves control to the developer
Flexible and powerful. Supports custom local storage layers. Detect and handle conflicts on server or client.
Push Notifications 101
Register device handle at app launch
Client app retrieves handle from Platform Notification Service (PNS)
Client app sends handle to your custom backend
Your backend connects to PNS and requests push Your code has to manage scale Your code has to map between logical users and device handles
PNS pushes notification to device
Maintain backend device handles
Your code must delete expired handles when PNS rejects them
Your code must map between logical users and device handles
Azure Notification Hubs
Client app retrieves handle from Platform Notification Service
Client sends handle to your backend Backend registers with Notification Hub using tags to represent logical users and groups
Backend sends request to Notification Hub using a tag Notification Hub manages scale Notification Hub maps logical users/groups to device handles
Notification Hub delivers notifications to matching devices via PNS
Notification Hub deletes expired handles when PNS rejects them
Notification Hub maintains mapping between logical users/groups and device handles
File management with Azure Mobile Apps
Backup and restore
In production A/B testing
Richer monitoring and alerting
