About Wintellect

Consulting/Training

Cloud and mobile are in fact one and the same.

The mobile devices that users are flocking to are useless

without the cloud.

And the cloud…is just a theory until you have a device that's

both powerful enough to run apps that can take advantage

of it and mobile enough that those apps are with you all the

time, and working on your behalf.

Consulting/Training

Putting “The Cloud” Into Your Apps

Platform API Strategies

Roaming Storage APIs – Device independence, but

locked into a platform

Storage Service Strategies

Storage Platform SDK’s – (eg OneDrive) Device and

platform independence

Limited to just data, no processing

“Backend as a Service” (BaaS) Strategies

Beyond just storage

Add services, logic, etc.

So where can I get some Cloud for my app?

Consulting/Training

Azure – A Tale of 2 Management Portals

Does Not Yet Support Mobile Services

Consulting/Training

A factory for creating REST APIs that can access several back-end services:

Provisioning and Management of Storage

Server-Side Business Logic with Source Control Integration

Authentication & Authorization

Push Notification Integration

Scheduled Script Execution

The Two Parts of Azure Mobile Services

Client libraries

Simplify using the REST APIs provided by the server

Client-side tooling (WAB, Offline Data Sync with SQLite)

Source code for the client libraries is available on GitHub:

http://github.com/WindowsAzure/azure-mobile-services

Consulting/Training

Getting Started with Azure Mobile Services Projects & the Azure Portal

Consulting/Training

Out of the box support for SQL Azure, Azure Tables, Mongo DB

For SQL Azure

Access via EF6 Code-First

Automapper support is included to provide DB Entity to DTO Conversions

Use DB Migrations for schema updates

3 Steps: Data Model, Data Context, Data Controller

Data is exposed as “Tables”

Data Storage

Consulting/Training

Data Model

public class {Model Class Name} : EntityData

{

public String SomeValue { get; set; }

etc…

}

Data Context

public class {Context Class Name} : DbContext

{

public {ctor} : base(connection string name) { }

public DbSet<{Model Class Name}> SomeItems { get; set; }

etc…

}

Working with SQL Server Data (1 of 2)

Id (string), Version (byte[])

CreatedAt, UpdatedAt, Deleted

Normally “MS_TableConnectionString”

Must match name in portal config

Consulting/Training

Data Controller

public class {Controller Class Name} : TableController<{Model Class Name}>

{

protected override void Initialize(HttpControllerContext controllerContext)

{

base.Initialize(controllerContext);

var context = new {Context Class Name}();

DomainManager = new EntityDomainManager<TodoItem>(context, Request, Services);

}

Controller Methods:

GetAllItems(), GetItem(id), PatchItem(id, Delta<> patch), PostItem(item), DeleteItem(id)

}

Working with SQL Server Data (2 of 2)

Consulting/Training

Working with Storage on the Server

Consulting/Training

With the .NET client library, apps can either use strongly typed data objects or dynamic JSON objects

With strongly-typed data, object/table and property/column names can be aliased

Using the DataTable attribute or the JsonProperty attribute

Table operations include

Query(where, skip/take, orderby/thenby)

Lookup (find by id)

Insert

Update

Delete

Consuming Data Tables (.NET apps)

Consulting/Training

private MobileServiceClient ms = new MobileServiceClient(

"https://{Site Name}.azure-mobile.net/",

“{Application Key}");

[DataTable(“{Table Name}"]

private class {Table or Custom Type Name}

{

public String Id { get; set; }

[JsonProperty(PropertyName=“{column name}")]public String OtherData { get; set; }

etc…

}

IMobileServiceTable<{DataType}> table = ms.GetTable<{DataType}>();

Interacting with Data Tables (.NET apps)

Optional configuration

Optional configuration

Optional value

Consulting/Training

Query

IMobileServiceTableQuery<{DataType}>query = table.CreateQuery();

Fluent Operations – return IMobileTableServiceQuery<T>:

Where, OrderBy/OrderByDescending/ThenBy/ThenByDescending,Skip/Take, IncludeTotalCount, WithParameters

Execution Operations – return results:

ToEnumerableAsync/ToListAsync (return all results)

ToCollectionAsync/ToIncrementalLoadingCollection(Win81/WP81) (support pagination/incremental loading)

var values = await query.Where(x => x.Field == value).ToCollectionAsync();

* Note – While IMobileServiceTable<T> includes several query methods, it simply delegates from table.{operation} to table.CreateQuery().{operation}

Table Query Operations (.NET apps)

Consulting/Training

Lookup by Id

var item = await table.LookupAsync(id);

Insert, Update, Delete

await table.InsertAsync(newItem);

await table.UpdateAsync(item);

await table.DeleteAsync(item);

Table Operations (.NET apps)

Note – after insert, the Id

property value is updated

Consulting/Training

// Uses JSON.NET

var entry = new JObject {{“FieldOne”, value1},{“FieldTwo”, value2}

};

var returnedItem = await ms.GetTable(“TableName”).InsertAsync(entry);

var addedItemId = ((JObject)returnedItem)["id"].Value<Int32>();

Just JSON Also Works (.NET apps)

Consulting/Training

Working with Storage from the Client

Consulting/Training

3 Execution Models for Server Code

Table Controller Methods (CRUD)

Custom API REST Endpoints

Scheduler Jobs

Services property provides access to Log, Push, Settings, Properties

Functionality can be extended with NuGet or other Assembly

references

Server-Side Business Logic

Consulting/Training

Server-Side Business Logic

Consulting/Training

Authentication & Authorization

Out of box support

Microsoft Account, Twitter, Google, Facebook, Azure Active Directory

“Secret Values” stored on the server in the Portal, behind the firewall

Custom Authentication Extensibility

Authentication Flows

Server-Flow: Server (Mobile Services) manages the authentication process

Client-Flow: Client authenticates on its own, passes token to server

Consulting/Training

[AuthorizeLevel(AuthorizationLevel.Application)]

public class TodoItemController : TableController<TodoItem>

{

[AuthorizeLevel(AuthorizationLevel.User)]

public async Task<IHttpActionResult> PostTodoItem(TodoItem item)

{

var user = (ServiceUser)User;

item.UserId = user.Id;

AuthN – Server Side

Controlled with AuthorizeLevel attribute

Can be scoped to Controller class or individual methods

Levels: Anonymous, Application, User, Administrator

Access authenticated user through (ServiceUser)User property

Consulting/Training

Server Flow

var accountType = MobileServiceAuthenticationProvider.MicrosoftAccount;

var user = await App.MobileService.LoginAsync({Account Type or Name});

var userId = user.UserId;

AuthN – Client Side (.NET)

Provider-specific ID value Account Type (MobileServiceAuthenticationProvider)

MicrosoftAccount,

Twitter,

Facebook,

Google,

WindowsAzureActiveDirectory

Name matches a custom authentication provider name

Client Flow

var token = { Use auth provider supplied API to retrieve an Auth token }

var user = await App.MobileService.LoginAsync({Account Type or Name}, token);

Consulting/Training

Using Authentication & Authorization

Consulting/Training

Library to simplify adding real-time communication over HTTP to applications

Uses WebSockets when available, falls back to other techniques when it isn’t.

More information:

http://www.asp.net/signalr

http://signalr.net/

In Mobile Services

Access Control – Same AuthorizeLevel on hub methods, or use config options’ SetRealtimeAuthorization to apply to all methods

Scaling – With Basic or Standard tiers (support scale-out), Azure Service Bus is automatically wired up as the backplane for syncing the service instances

SignalR

Consulting/Training

Add the NuGet Package

install-package Microsoft.AspNet.SignalR

Initialize SignalR

SignalRExtensionConfig.Initialize();

Sending Messages

var hubContext = Services.GetRealtime<SettingsHub>();

hubContext.Clients.All.testFunc(param1, param2);

hubContext.Clients.{filter}.{call}({arguments});

Using SignalR on the Server

All, Caller, Others, Client(connectionId),

AllExcept(connectionIdList), Group(Name),

OthersInGroup(groupName), User

Dynamic, matches client-side

Consulting/Training

Add the NuGet Package

install-package Microsoft.AspNet.SignalR.Client

Create a Connection, Generate a Proxy, and Start the Connection

var hubConnection = new HubConnection({Uri});

var proxy = hubConnection.CreateHubProxy({HubName});

await hubConnection.Start();

Receiving Messages

connection.On<type>(“message-name”, (type) =>{…code…})

Sending Messages

proxy.Invoke(“method-name”, “param”)

var result = await proxy.Invoke<{resultType}>(“method-name”, “param”)

SignalR on the Client

Type is optional, if server is

not sending parameters
