C# 5.0 includes the async and await keywords to ease writing of asynchrono

In desktop .NET 4.5, and in Windows 8 .NET for Windows Store Apps, new T

methods allow networking calls as an asynchronous operation using a Task

HttpClient API

WebClient.DownloadStringTaskAsync(), DownloadFileTaskAsync(),

UploadStringTaskAsync() etc

HttpWebRequest.GetResponseAsync()

These methods are not supported on Windows Phone 8

Task-based networking using WebClient and HttpWebRequest still pos

TaskFactory.FromAsync() and extension methods

Coming up later

Async support in WP8 Networking APIs

Connecting the Emulator

to Local Services


11/63

In Windows Phone 7.x, the emulator shared the networking of the Host PC

You could host services on your PC and access them from your code u

http://localhost...

In Windows Phone 8, the emulator is a Virtual machine running under Hype

You cannot access services on your PC using http://localhost...

You must use the correct host name or raw IP address of your host PC

Windows Phone 8 Emulator and localhost
http://localhost/http://localhost/

WCF Service Activation

If your service is a WCF service, you must also ensure that HTTP Activation

Also run the following at the command prompt:

netsh http add urlacl url=http://yourPC:18009/ user=everyone

Substitute yourPC with the host name of your Host PC

Substitute 8080 for the port where your service is running

ASMX should just work

WCF requires that you use

basicHttpBinding

WCF/ASMX Services


30/63

RESTful Web Services

Building them

Rather than building walled gardens, data should be published in a way tha

reach the broadest range of mobile clients

Old-style ASMX SOAP 1.1 Web Services using ASP.NET or Windows CommunFoundation (WCF) require clients to implement SOAP protocol

With Windows Phone 7 and Silverlight, we use WCF with BasicHttpBinding band as a Web Role in Windows Azure to publish our data from local and clousources like SQL Azure

Recommend using lightweight REST + JSON Web Services that are better ophigh-latency, slow, intermittent wireless data connections


31/63

WCF Data Services: OData

WCF Data Services provide an extensible tool for

publishing data using a REST-based interface

Publishes and consumes data using the OData web

protocol (http://www.odata.org)

Formatted in XML or JSON

WCF Data Services Client Library

(DataServicesClient) is a separate download from

NuGet

Adds Add Service Reference for OData V3 Services

Making Decisions based on Data Connections

Mobile apps shouldnt diminish the user experience by trying to send or rec

the absence of network connectivity

Mobile apps should be intelligent about performing heavy data transfers or

remote method calls only when the appropriate data connection is available

With Windows Phone, we use the NetworkInterfaceType object to detect nespeed and the NetworkChange object to fire events when the network

state changes

Implementing Compression on Windows Phone

Implementing Compression on Windows Phone

Windows Phone does not support System.IO.Compression.GZipStream Use third-party solutions instead SharpZipLib is a popular C#compression library (http://sharpziplib.com/) SharpCompress is another (http://sharpcompress.codeplex.com/)

On Windows Phone OS 7.1, get GZipWebClient from NuGet Replaces WebClient, but adds support for compression Uses SharpZipLib internally NuGet release for Windows Phone 8 not yet available (as of October 2012)

Until updated library released on NuGet, source is available online

Data Sense

Data Sense API


49/63

The Data Sense feature allows a user to specify the limits of their data plans and moni

Your app can use the information provided by the Data Sense APIs to change data usa

Reduce data usage when the user is close to their data limits

Discontinue data usage when the user is over their limit

Or to postpone tasks that transfer data until a Wi-Fi connection is available

Data Sense is a feature that Network Operators optionally support

Provide a Data Sense app and Tiles to allow users to enter their data limits Routes data via a proxy server in order to monitor data usage

If Data Sense is not enabled, you can still use the APIs to determine if the user is conne

is roaming, but you cannot determine the users data limits

Using the Data Sense APIs

1. Get the Network Type from the

ConnectionProfile by calling NetworkInformation.GetInternetConnectionClient

2. Get the NetworkCostTypeby callingConnectionProfile.GetConnectionCost

3. Get the ApproachingDataLimit,OverDataLimitand Roamingproperties of theConnectionProfile

Network Security

Encrypting the Communication


53/63

You can use SSL (https://...) to encrypt data communications with servers tha

server cert

Root certificates for the major Certificate Authorities (Digicert, Entrust, Veris

built into Windows Phone 8

Your app can simply access an https:// resource and the server certifica

automatically verified and the encrypted connection set up

SSL Client certificates are not supported, so mutual authentication scenpossible

You can install a self-signed cert into the Windows Phone Certificate Store

Expose the .cer file on a share or website protected by authentication

Alllows you to access private servers secured by a self-signed server ce

Encrypting the Communication

Authentication


54/63

Authentication

As well as encrypting data in transit, you also need to authenticate the clientthey are allowed to access the requested resource

For communications over the Internet, secure web services using Basic HTTP Transfers the username and password from client to server in clear text, so used in conjunction with SSL encryption

For Intranet web services, you can secure them using Windows or Digest aut Windows Phone 8 supports NTLM and Kerberos authentication
