• Background location-tracking apps
• Run continuously in the background when the user
navigates away from the app
• Enables scenarios such as Run Trackers, turn-by-
turn navigation
Location and Location Tracking

19. • Windows Phone 8 allows you to enable users to robustly interact
with your app using their voice
• Two types of voice interaction are new:
• Voice Commands - Allows users to deep-link into your app by
holding down the Start button and speaking a prefix you
specify for your app, followed by a command that you define.
• Speech Recognition and Text-to-Speech APIs - While in the
context of your app, allow users to provide input using their
voice, and readout text to users via text-to-speech

21. • Create apps that communicate with other phones using Bluetooth technology
• Bluetooth API enables the following scenarios for Windows Phone 8:
• App-to-app communication
• App-to-device communication
• Proximity API enables:
• App-to-app connection using Bluetooth technology
• Establish a Wi-Fi, Bluetooth, or Wi-Fi Direct connection between your app and an
instance of your app on a proximate device
• Send data between devices using NFC.
• Use a phone to interact with NFC tags
Bluetooth and NFC

22. Better Sharing with NFC

23. • App can register a File Association
• Automatically launch your app when a file of the registered type is
received as an email attachment or opened in the browser, or through
Sharepoint
• One app can launch another by sending it a file of the registered type
• App can register a protocol
• Allows your app to automatically launch when another app ‘opens’ a
special URI
• Protocol is the first part of a URI, e.g.
myprotocol:/ShowProducts?CategoryID=aea6ae1f
• App launches another and passes it data in the remainder of the
launch URI
File and Protocol Associations
Enables App to App Communication

24. In-App Purchase used for digital content
Durables: buy once & own forever,
e.g. new game levels, maps, game items
Consumables: game currency, movie
rentals, access to digital magazines for 6
months, etc.
Offer digital assets

27. • Managed Apps are NGEN’d for you (compiled to native) in the Windows Phone Store in
Windows Phone 8, so typically start and run faster 
• When you build your app in Visual Studio, the code is not compiled into a native image,
but into a machine-independent Common Intermediate Language (CIL) binary file
(formerly known as Microsoft Intermediate Language, or MSIL)
• When you submit your app to the Windows Phone Store, you submit the CIL file
• On submission, CIL file is converted to optimized Machine Dependent Intermediate
Language, or MDIL
• When a user downloads your app to a device, it is pre-jitted to a native image
Windows Phone 8 Apps Run Faster 

31. • The Windows Phone Store is the only way you can get executable content onto a “public”
phone
• Enterprises can register with Microsoft to allow them to distribute applications to
devices that have been enrolled into their Enterprise
• Users can buy applications and deploy them onto their devices
• Developers can write applications and deploy them to their own devices for testing
• Registered developers can use up to 3 devices
• Student developers can use one device
Windows Phone Store Rules

32. • Register to be a publisher in the Windows Phone Store for $99 per year
• Students can register for free via Dreamspark
• Registered developers can submit applications for approval in the Windows Phone Store
• Windows Phone dev account members have their identity validated when they join and
are allocated a unique digital signature to sign their Windows Phone Store submissions
• Join at: http://dev.windowsphone.com
Joining the Store

33. • Developers can set a price for an application or give it away free
• Developers receive 70% of the price paid for the application
• Payment starts once the developer has earned up to $200
• The payment is made by bank transfer
• All payments are from the USA, which can cause some issues
• Very good support on the developers site and the Windows Phone Forums for this
Payment

34. • Developers are limited in the number of free applications they can make available
• Only 100 (!) free app submissions per developer per year
• Can make additional free application submissions at an extra cost of $20 per submission
• Developers can publish as many paid applications as they like
• Number of apps any one developer can have certified in a single day is limited to 20
• Avoids bulk publishing flooding the market
Free and Paid Applications

35. • Applications can be free or paid
• Developers can also allow customers to use an application in “try before buy” mode
• Your application can determine which mode it is running in by calling a status API
• Applications sold on a “try before buy” basis don’t show up as Free Applications
• This may reduce the number of people who will download it
• Some people only browse the free lists
“Try before Buy” mode

36. • It is easy for an application to determine whether it is running in Trial mode
• But remember that a paid application with Trial Mode will not show up as free in the
Windows Phone Store
• It might be more effective to also distribute a free “lite” version of your application
which can be upgraded by an in-application purchase
Detecting Trial Mode
using Microsoft.Phone.Marketplace;
LicenseInformation info = new LicenseInformation();
if ( info.IsTrial() )
{
// running in trial mode
}

37. • Windows 8 allows you to sell upgrades and additional features to users from within your application
• There are two kinds of purchase
• Durables are bought once
• They can be used to activate program features or game levels
• Consumables can be purchased repeatedly
• They can be used to buy any resources (access time, in game currency) that will expire and must be
replaced
• Apps can be sold as a Free app or at a low initial purchase price but offer reduced functionality, and
then use in-app purchase to allow the user to buy access to additional features
In-Application Sales

38. • The Advertising SDK is distributed as part of the Windows 8 SDK
• You need to add the assembly to any project that wants to include adverts
In-App Advertising

39. • Very easy to incorporate ads into applications
• The Ad-Control SDK provides the adControl that can put adverts onto your application
• The AdManager can be added to XNA games
• Players can click through an advertisement to a web site or call the advertiser from within
your game
• Advertisements are specifically targeted at each player demographic
• You get 70% of the revenue
Adding Advertisements to Applications
AdControl adControl = new AdControl("test_client", // ApplicationID
"Image480_80", // AdUnitID
true); // isAutoRefreshEnabled

40. Microsoft pubCenter
• Sign up here so that you can incorporate ads in your games http://pubcenter.microsoft.com

42. • When you submit your application for validation the Microsoft app validation
service performs a number of automated tests
• Checks if the application makes use of any capabilities that were not specified
• Checks for any unmanaged or disallowed libraries
• Ensures that all the required assets are provided
• Then the application is manually tested to ensure proper behaviour in a
number of scenarios
• Proper dormant/tombstone behaviour
Application Validation

43. • The testing process takes a few days and generates a testing report that you can use
to fix the problems
• This will include specific feedback on the issues that were identified
• When the application is resubmitted the retest will focus only on those parts of the
application that have changed
Validation Results

44. Private Beta Testing
• Apps can be submitted for Private Beta testing
• You can send invitation emails to up to 10,000 testers who will receive a deep link
to the beta application
• They have 90 days to test your application and give you feedback
45

45. • When you submit an application, you have the option of making it
‘Hidden’
• It will not appear in any Windows Phone Store listings or searches
• It is still verified and certified and published in the same way
• You can still link to the app – if you know the link
• You can create a dashboard app to distribute to your user community
which allows them to discover and install the hidden apps
• Keeps the link to the app in the Store undisclosed
• Safer than insecure ways of communicating the App location by email
or messaging
• Lightweight alterative to full Enterprise Distribution
Private Distribution

46. Windows Phone Applications in the Enterprise
• Windows 8 allows enterprises to configure enterprise wide application distribution
• The enterprise can create and distribute Windows Phone applications without requiring
them to be approved by the Microsoft Windows Store
• User phones can either be managed or unmanaged
• Very high level of control over a managed phone
• An unmanaged phone can be used in a “Bring Your Own Device” mode
• An Enterprise can create its own Application Hub which can be made available on
managed devices

47. Company Hub Example
• Microsoft have created an internal Company hub that provides corporate information
alongside other information
