    How do you build a Windows Store Line-of-Business app?


    imageWhen building a line-of-business (LOB) app there are numerous things to consider.  Of course you need a great user experience, but what about validating user input, user authentication, how do you deal with application state across suspend-resume, do you roam app state across devices, and there is much more to think about.

    Now you can accelerate your development time to build a Windows Store LOB app. A couple of days ago the Pattern & Practices team have released Prism for Windows Runtime and the associated AdventureWorks Shopper reference implementation to the Windows Dev Center.

    What is Prism for Windows Runtime?

    The Prism for Windows Runtime release provides you guidance to help you more easily design and build flexible and easy-to-maintain Windows Store apps using C# and XAML and the Windows Runtime.

    Prism comes with the AdventureWorks Shopper reference implementation which uses the Prism library to demonstrate modern development practices such as Model-View-ViewModel (MVVM) pattern with navigation and app lifecycle management. Additionally the reference implementation demonstrates validation, application data management, accessibility, localizability, touch, search, tiles, tile notification, and multiple view states.


    Where do you get started?

    The Prism library source code is available with the AdventureWorks Shopper reference implementation on the MSDN Code Gallery at The Prism binaries will also be available on NuGet starting Monday May 20. Search for Prism.  You can view the documentation at or download a PDF version at

    Check also our local Apps on Windows portal for more resources on how to develop apps for Windows 8, Windows Azure and Windows Phone – you can find local trainings and events, contests and links to online training resources.

    Windows Azure Infrastructure as a Service General Availability



    Microsoft just announced the general availability of our Windows Azure Infrastructure as a Service (IaaS) support! With this release Azure Virtual Machines and Virtual Network move out of Preview and are now ready to use for your production apps.

    With Azure Virtual Machines you can deploy and run durable VMs in the cloud, provisioned from prebuilt templates or alternatively upload your own custom-built VMs.  All this in a matter of seconds!  Azure Virtual Network allows you to securely bridge between your on-premises infrastructure and your infrastructure in the cloud. This gives you the flexibility to run your workloads where you want, but manage them all in the same way.

    Whether you want to securely extend your on-premises network to Windows Azure or you want to create a virtual private network with persistent private IPs..

    Let’s look in more detail into what we have announced today:

    • For memory intensive scenarios, we are now introducing two high-memory compute instances: 4 core x 28GB RAM and 8 core x 56GB RAM. With these VM sizes you can run even larger workloads on Windows Azure, for example SharePoint Server or SQL Server workloads.
    • We have added several new VM image templates to the Image Gallery, such as SQL Server 2012, BizTalk Server 2013 and SharePoint Server 2013 images. These images also come with hourly billing, so you don’t have to pay for an upfront license.
    • We have updated the SLA for Virtual Machines and Virtual Network.  For VMs that have 2 or more instances deployed in the same availability set, we have a 99.95% SLA for external connectivity.  For Virtual Network, we guarantee a 99.9% Virtual Network Gateway availability.
    • As of this announcement, Virtual Machines and Virtual Network are now supported by Microsoft Support staff, so you can confidently run your production apps on Azure.


    On top of all these great features, we’re also announcing significant pricing reductions to our Windows Azure PaaS and IaaS VM pricing. You can expect to see from 20% (Virtual Machines) to 33% (Cloud Services) price reductions! These new prices are effective as of June 1.  And as of today, we’re also adding 50 hours of free memory-intensive-instance hours to our member offers and 90-day trials.

    For a more detailed description of the announcement, you can check out Scott Guthrie’s blog post.

    If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Did you know that you already have a lot of free Azure resources as part of your MSDN, MPN or BizSpark membership? 

    If you want to learn more about our Windows Azure IaaS capabilities, don’t forget to listen in on our dedicated IaaS webcast on April 30. If you want to experience this great technology hands-on, join us for our Azure IT Camp on May 6.

    Also don’t forget there is a virtual conference runnning next Tuesday April 23rd:

    Windows App Day – slides and video from the event


    A small month ago on November 23rd we welcomed over 200 attendees to our first Windows App Day in Antwerp, focusing on developer and User Experience/web content for building apps. What types of apps you ask? A lot of it was centered around Windows 8 Store apps but also Windows Azure and mobile services as well as Windows Phone 8 Platform.

    We kicked off by an opening session with Luc Van de Velde, director of our Developer Platform team; followed by the presentation of several cases. I would like to thank our partners for being on stage with us:

    1. Alain from Nascom with the Bumba Windows 8 app. App was built in HTML5 using CreateJS, you can read about the migration from iOS game experience here.
    2. Persgroep with the apps for De Morgen, Het Laatste Nieuws and others;
    3. Brecht Kets from Howest University on the student games created using MonoGame
    4. Johan Peeters on his experiences with Windows Phone development and the Belgian Apps app. Note: Johan is currently working on the “Belgian Apps” for Windows 8 too. If you are interested in beta testing contact him through Twitter.
    5. Twipe Mobile on their digital newspaper platform partly based on Windows Azure, and presenting the case for the Windows 8 app for “De Standaard’.

    A big thanks to my colleagues too for joining me on delivering a team keynote. We all had lots of fun presenting it.

    The content, videos and speakers

    Looking at the session evaluations and by talking to many of the attendees, we know folks especially appreciated some of the less typical sessions, that is: the UX guidance for Windows Store apps. For example, Bart Claeys’ session on migrating an iOS app to Windows Store was hugely popular.

    The good news: you’ll find the sessions slides below, and available at the MSDN Belux SlideShare.


    Even more: most video recordings of the sessions are now also online on Channel9. Do note that some of the coding sessions’ recording quality is not what we would consider optimal. We still chose to publish them as it might be interesting for folks that want to review something they missed in a session.

    Cloudify your Windows 8 and iOS apps with Windows Azure Mobile Services


    Leveraging my colleague Nick’s post on Windows Azure Mobile Services here. WAMS has received an upgrade, now supporting iOS next to Windows 8, and including new authentication support, sending e-mails, SMS en more.
    If you are from Belgium or Luxembourg, and are thinking about leveraging WAMS for your Windows 8 or iOS apps please let us know. We’d like to hear about your experiences.


    With the introduction of apps and application stores, the process of building, selling and distributing software has been truly democratized.  But what if your application becomes a top hit and is being downloaded and used by millions of users?  How do you make sure that your backend services scales dynamically with this unpredictable demand?

    Windows Azure Mobile Services makes it incredibly easy to connect a scalable cloud backend to your client and mobile applications.  It allows you to easily store structured data in the cloud that can span both devices and users, integrate it with user authentication, as well as send out updates to clients via push notifications.


    Windows Azure Mobile ServicesA couple of weeks ago we announced Windows Azure Mobile Services with support for Windows 8 apps. This week we delivered initial support for connecting iOS based devices (including iPhones and iPads) to Windows Azure Mobile Services.  We’ll also be adding support to enable these same scenarios for Windows Phone, and Android devices soon.


    In addition, we have also released the following great improvements to Windows Azure Mobile Services:

    • Facebook, Twitter and Google authentication support
    • Sending emails from your Mobile Service, in partnership with SendGrid
    • Sending SMS messages from your Mobile Service, in partnership with Twilio
    • Support for connecting to Azure Storage and Azure Service Bus


    Read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple iOS “Todo List” app that stores data in Windows Azure.  Then follow the below tutorials to explore how to use the iOS client libraries to store data and authenticate users.


    image If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services.

    Marketing material: your app on Windows Store


    If you have an app published on the Windows Store, chances are you want to let the world know. Which visuals should you use? How about a Windows Store app badge. What’s the guidance and wording?

    Since a few days you can find this guidance on the Windows DevCenter: Windows Store logos and usage specifications

    The documentation contains the following:

    • License to Microsoft Marks
    • Windows badge info
    • License to Microsoft Marks
    • Windows Store badge
    • Windows Store tile
    • Tablet and laptop device chassis visuals: includes layered high-res .PSD files, with 10 images on different perspectives
    • Windows Store localized info and terms: for example, did you know that for Belgium we name it “Windows Store” in both French and Dutch, while in Afrikaans the Windows Store is called “Windows Winkel”. And in Luxembourgish we’ll just say “Windows Store” too. That makes it easy for all of us in BeLux area.

    Windows Store – App Certification Tips


    Windows 8 launches globally on October 26th, as we move closer and closer, we’re supporting many Belgian developers go through the process of certifying their apps. To help other developers we might not be in touch with, I’m sharing an aggregation of tips and resources we use. It’s worthwhile browsing through this post before you submit so that you increase the chance of passing certification from the first time.

    The tips are based on what we have been working on, many times it’s small things that you can have fixed before you submit, such as forgetting a support contact or privacy policy. We’ll be updating this post as we move along.

    Before going into the details, keep the following resources handy when certifying apps on Windows Store.

    Most recurring omissions

    From our experience, this is what I ask developers before they submit:

    1. Have you created a Privacy policy settings entry in the Settings charm?
    2. Have you added a Privacy URL info in the Additional details of the Store Portal dashboard? See below.
    3. Have you set your Default language correctly in the App Manifest? See below.
    4. Are your Capabilities correct? Remember capabilities also influence requirements around age rating and privacy. If you do not need Internet access, make sure to uncheck the capability as it is checked by default.


    Store Portal: Description Page

    In the description page of the Store portal, after you submit your package, you will be able to enter the details for the Windows Store app listing. For a complete overview of the content needed to complete this page, please see the Dev Center Checklist for submitting an app. This is a great resource to send to your business team as they will provide visuals, description, features and category information in each language the app supports.

    Support contact

    Failing to fill in the Support contact URL or e-mail address will have your app rejected. Double-check the content you are entering here.

    Add a Privacy URL

    We also recommend you add the same privacy URL as an entry in the app settings pane.

    Choosing the right Age Rating

    Review the guidance: Pick a suitable Windows Store age rating and Give your app an age rating.

    Linked to the Age rating, make sure the screenshots you upload for your app listing (metadata) are viewable by 12+ if your app requires higher age rating.


    Before submission

    Language of the package, default language and multiple languages

    Windows Store allows for global distribution. This is a huge potential you should take advantage of, and which will be even more successful if you offer the app in several languages.

    When uploading the app package to the Store, detection of the supported languages is done through the AppManifest resources. Make sure you entered your default language correctly (default might go to en-US depending on your version of Visual Studio).
    Open the AppManifest file in the XML editor.

    Case 1: single language (US English)

    For English, you can either leave the default setting (x-generate) if you are using an English version of Visual Studio or adapt manually:

         <Resource Language="en-us"/>

    Case 2: single language (only Dutch for both Belgium and Netherlands)

        <Resource Language="nl" />   

    Case 3: several languages (English, French and Dutch as example)

    The first language in the list is the default language. We are using the country code to make it more specific. You can choose to omit it.

       <Resource Language="en-us" />
       <Resource Language="fr-be" />
       <Resource Language="nl-be" />
    < /Resources>

    Privacy policy in settings pane (charm)

    Many applications use the Internet capability, for which a privacy policy URL is required in the Store portal. Note that this is a very important one and also linked to activating a number of capabilities such as:

    • SMS
    • Text messages
    • Location
    • Microphone
    • Webcam
