I grew up in the nineties, that makes me awesome by default

What I expect from the WP summit's keynote

by Nico

Tomorrow we will get the first details of the next Windows Phone version. A moment I've been waiting for since the first details of Apollo (the codename for WP8) started showing up. That said, I feel like a kid the evening before Christmas, staring at presents unable to open them or to take a peek inside.

What do I expect from the keynote? I expect announcements concerning new resolutions, multi-core CPU's, private marketplace, IE10, NFC, Wallet, new camera features, swappable SD cards.

Those are the most obvious things and I'm pretty sure that we'll hear about 95% of them tomorrow. Besides this I hope to hear from WP 7.7 or even better, existing devices will get a complete upgrade to WP8.

And let's not forget the dev related stuff, WP8 will run on WinRT, the kernel used in Windows 8, allowing devs to share 99% of apps between Windows Phone, Windows 8 and maybe even Xbox. I also hope for beta SDK availability tomorrow at the event and a release date set at about the same time as Windows 8 (around October). Maybe we'll even get some early access to the Smartglass SDK, that would be a whole lot of epicness.

No matter how it turns out, I'm pretty confident that it will be awesome. I'm already looking forward to using the complete WinRT ecosystem, but even more to developing apps that plug into each and every WinRT client.

I'll be following the livestream with our User Group's board and our friends at Microsoft while enjoying some beer and pizza, so setting is perfect. I'll also be spamming Twitter, so keep an eye on it there.

BEWARE: everything I talked about in this post is my own opinion, I have no knowledge of what effectively will be shown at tomorrow's keynote.

Will Microsoft pull a hattrick?

by Nico

Microsoft has had a busy week and currently is the topic on social media. How come? Well for starters at their E3 (Electronic Entertainment Expo) they announced SmartGlass, a technology that connects the devices throughout your home. You can, for example, start watching a movie on your phone on your way home, keep watching it on your television by using your Xbox360 and then finish it on your tablet when your wife wants to see her favorite soap opera. And the best part of this? It will all be free, it’s just an app on your phone, tablet and/or xbox. It will even be available on iOS and Android. That’s right! Microsoft is supporting the competition now, although it’s pretty safe to assume that the Windows ecosystem will have some extra features compared to Google and Apple.

So pretty impressive start of the week for Microsoft, techies around the world (myself definitely included) were pretty excited about this announcement. Skip ahead a few days later, today on Thursday 7th of June Microsoft announced the next version of Windows Azure, their cloud based platform. And what an announcement it was! Scott “The Gu” Guthrie showed off some of the new features and the world saw that it was good. Azure will include features like Caching, Media Services, Virtual Machines and Websites. You will be able to setup a virtual machine locally and upload the VHD to the cloud, and it doesn’t even have to run a Microsoft operating system. Azure now has support for Linux virtual machines. They have a partnership with Suse and Ubuntu to offer you the server versions of their OS with all the scalability features that a Cloud OS should have. Next to that you can soon host your blog in the Cloud with a free website subscription (free as in free for a year, definitive pricing isn’t known yet). This feature has support for PHP and obviously but Azure now brings support for Python as well. Oh and on a “small” sidenote: you can use MySQL now for your Azure apps. There’s a lot more announced for Azure today, just take a look at the keynote or read the blogs from the various Azure MVP’s. Or just search for #meetazure on Twitter but prepare to have your mind blown.

So that’s two days that Microsoft succeeded in actually announcing spectacular technologies, social media is exploding in awe, screaming that Microsoft is finally doing it right. I really agree with this. Datacenters and webhosting companies will have a difficult time competing against the Azure system. Even vmWare and Amazon AWS are facing dark times. In my opinion, Microsoft has officially won the war for the living room with SmartGlass and the war for the cloud with Azure vNext.

So what remains then? The war for the mobile world obviously. At the moment this war is being fought by Apple and Google, ammo mostly being patents. But on June 20th the WP7 summit will start, the keynote will be live streamed just like Azure’s keynote today. So if you put 2 and 2 together, it’s pretty obvious that MS will be announcing WP8 end of this month. If all the rumours about WP8 prove to be true they will effectively surprise the big audience a third time in one month, thus pulling a hattrick.

And how I hope they do! It’s long overdue that they succeed in changing their image from a monster company only interested in money. That was maybe true years ago, but to me they now are a company that dares to innovate, Windows 8 is the biggest proof of that. And they actually listen to their users while supporting the open source scene. Who would’ve thought that of the big bad Microsoft?

To wrap things up, I really like where they are going with all this. I enjoy Windows 8 a lot these days, I’m impressed by both SmartGlass and Azure and I’m eagerly awaiting Windows Phone 8. You’re doing great Microsoft, keep it up!


Visug: WP7 live tiles slides and demos

by Nico

Yesterday I did a session about Windows Phone Live Tiles at Visug. Visug is the Belgian Visual Studio User Group.

I had a great time, lots of fun, met some nice people, had some drinks and laughs. All in all a very productive evening. Except for the Microsoft Proxy (the event was hosted by Microsoft Belgium) that blocked my connection to the Microsoft Push Notification Service (go figure...).

Anyway, I hope to speak at Visug again in the future, the slides and demos from yesterday's event can be downloaded here.

Community Day 2012

by Nico

Here in Belgium we .net developers have an awesome community. An entire washlist of User groups (including the Windows Phone User Group that I'm a founding member off) that organise free events on a regular base.

Once a year all user groups get together for a full day, completely free event called Community Day. This year Community Day will take place on June 21st and will have 6 tracks full of IT-pro and developer sessions.

For me it will be the third time that I'll attend this great event but it will be my first time actually doing a session there, I'll be presenting about converting a Windows Phone 7 application to Windows 8 Metro. I'm really looking forward to this as I never talked in front of such a big audience, let alone did a talk in a movie theatre.

If you're attending as well, feel free to come talk to me about anything.


See you there!


Filtering collections from XAML using CollectionViewSource

by Nico

I find that I often run into the need of separating a collection of items into several collections just so I can bind them to multiple listboxes, for example a list of sessions spanning several tracks and each track is shown in his own listbox in a pivotitem. To get this done you can start by adding multiple collections to your viewmodel and divide the items there. However this makes your viewmodel very big in a very short time. A better way to do this is using CollectionViewSource items in XAML. Let me show you how.

First thing I did was building a demo class existing out of a title and a description, these two properties will be shown in the listbox later on. A third property is the one we’ll use to filter the data, here’s the completed class.

public class DemoClass
    public string Title { get; set; }
    public string Description { get; set; }
    public Pivot PivotToAppearIn { get; set; }

Nothing special here. Notice the Pivot instance, this is just an Enum that will be the way to filter later on.

public enum Pivot

For the demo’s purpose I’ll be creating a bunch of dummy data in the viewmodel. The project template I’ve used here is the default pivot app template in the Windows Phone 7.1.1 SDK. It comes with a bunch of dummy data, I’ve used the same data but put them in instances of the DemoClass. Those instances are put inside an ObservableCollection.

This is the viewmodel

public class MainViewModel : INotifyPropertyChanged
    public const string ItemsPropertyName = "Items";
    private ObservableCollection<DemoClass> items;
    public ObservableCollection<DemoClass> Items
            return items;

            if (items == value)

            items = value;

    public MainViewModel()
        this.Items = new ObservableCollection<DemoClass>();

    public void LoadData()
        Items.Add(new DemoClass 
            Title = "runtime one", 
            Description = "Maecenas praesent accumsan bibendum", 
            PivotToAppearIn = Pivot.First 

    public event PropertyChangedEventHandler PropertyChanged;
    private void NotifyPropertyChanged(String propertyName)
        PropertyChangedEventHandler handler = PropertyChanged;
        if (null != handler)
            handler(this, new PropertyChangedEventArgs(propertyName));

So we’ve got our basic bindable property here and a method that loads in the dummy data. In the demo project there’s obviously more then one item in the collection, there’s about 16 to be precise.

In the design I didn’t change a lot from the default template. I’ve just copied the ItemTemplate from the listbox to the pageresources so that it can be reused in the second listbox.

This is the template.

    <!-- template for the listboxes -->
    <DataTemplate x:Name="ListBoxTemplate">
            <StackPanel Margin="0,0,0,17" Width="432" Height="78">
                <TextBlock Text="{Binding Title}" TextWrapping="Wrap" 
                           Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                <TextBlock Text="{Binding Description}" TextWrapping="Wrap" 
                           Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>

All right now that the preparations are set, time to get into the filtering. First step is to add a CollectionViewSource for each listbox. These are set on the same place as I’ve put the listbox ItemTemplate, in the pageresources. For this demo I need two CollectionViewSources.

<CollectionViewSource x:Name="FirstPivot" Filter="FirstPivot_Filter" Source="{Binding Items}" />
<CollectionViewSource x:Name="SecondPivot" Filter="SecondPivot_Filter" Source="{Binding Items}" />

So what’s all this? x:Name is like in any other XAML object, it’s just the name that can be used to reference the object. The source is the ObservableCollection that was created in the viewmodel. And last but definitely not least is the Filter event. This event will fire for every item in the collection that is bound to the Source property.

Now for the event handler, I’ll just post the event handler FirstPivot_Filter here because they are basically the same.

private void FirstPivot_Filter(object sender, System.Windows.Data.FilterEventArgs e)
    e.Accepted = (e.Item as DemoClass).PivotToAppearIn == Model.Pivot.First || 
        (e.Item as DemoClass).PivotToAppearIn == Model.Pivot.All;

FilterEventArgs has two properties, Accepted is a boolean that when true shows the item in the listbox that is bound to the CollectionViewSource. Item is the current item in the collection. Remember that this event is triggered for each item in the collection. So what we do here is casting the Item property to an instance of DemoClass then check if the PivotToAppearIn property, that was an instance of the enum, is either First or All.

Now that we have the CollectionViewSources and the event handlers in place it’s time to bind the ViewSource to the listbox.

<controls:PivotItem Header="first">
    <ListBox x:Name="FirstListBox" Margin="0,0,-12,0" 
             ItemsSource="{Binding Source={StaticResource FirstPivot}}"
             ItemTemplate="{StaticResource ListBoxTemplate}" />

The bindingsource of ItemsSource is bound to the CollectionViewSource that filters for this listbox. And that’s it!


In this article I’ve shown how you can filter a collection using a CollectionViewSource in XAML. This is an easy and fast way to visually filter data while keeping a clean ViewModel.

Not another rant on Windows 8

by Nico

So Windows 8 consumer preview is available for a couple of weeks now and I see a lot of different reactions. Most negative reactions I’m seeing is about the Metro UI. I don’t understand why people don’t like it, personally I love the Metro UI and here’s why.

First of all, stop begging Microsoft to bring back the old Start menu. This is called innovation people, if Microsoft never changed the UI of Windows we would all still be working on this:

So nothing wrong with some good innovation. Yes I know that change can be scary, but just really how different is Windows 8 from Windows 7? When you take a closer look at it Windows 8 takes features from Windows 7 that have proven their worth and improves on them.

Don’t believe me? Let’s take the Start menu for example. The Windows 7 start menu has this really great feature that is the search box. Hit the Windows key on the keyboard, type the name or part of the name of the application you want to open and Windows performs a real-time search with the results being displayed inside of the start menu.

You can do the same in Windows 8, when on the Metro UI just start typing and Windows starts the same real-time search with the results being displayed in the Metro UI. So more space for the results and you can even specify where you want to search, on your pc, in your mails, on the web, etc. all from the same feature that we’ve come to know and love in Windows 7.

The Start menu in Windows 7 has a great way of showing your most used applications so you can easily access them. The Start screen in Windows 8 lets you organise and order every application in the way you prefer and makes you feel most comfortable. Another good concept made great.

The Windows 7 Start menu has some links to administrative tools like the Control Panel, Devices and Printers, Computer, … stuff that is only used by those who know what they’re for, so it’s mostly wasted space. In Windows 8 all these options and a lot more are hidden behind a right-click context menu, something the power users will definitly find and won’t bug the “normal” users.


Next on the list of big improvements is the “All Programs” option in the Windows 7 Start menu, this just lists all folders inside of the Program Files and Program Files (x86) directories, it should be called “All Directories” instead of All Programs. Also due to the rather small nature of the Start menu only about 20 items can be seen without scrolling and they are really tiny. In Windows 8 I can place up to 60 items on one screen without scrolling, even when I divide them all into groups I get way more apps in my Start screen and it’s the shortcuts to the app themselves, not their installation folder.


Enough about the Start menu and the Start screen. Let’s take a look at Windows explorer. The explorer in Windows 7 had some nice shortcuts depending on where you are. For example when you open “Computer” you get this:

Really cool way to get to System Properties, Control Panel, map a network drive, etc. Now in Windows 8 they’ve implemented the Ribbon like it exists in Office 2007 and 2010. However since some people out there don’t like the Ribbon for some obscure reason it starts collapsed.

After a click on the small white arrow in the upper right corner it turns into this:

Same options but more visually. The fact that they are bigger and have an icon makes them more accessible.

Now let’s take a look at some features that are new to Windows 8. For example, when you right click on the metro UI there’s an option to show all apps. On this overview when you click the zoom button in the bottom right corner you can select a letter or a group to quickly jump the applist to your selection.

Another new feature is the charms bar. This appears when you place the mouse cursor in the upper right corner of the screen, or on a touchscreen you can draw the bar in from the right. This bar contains a Start button that will take you to the Start screen. It has a Search button which does the obvious. The devices button shows all plugged in devices like printers, scanners, secondary monitors, etc. The Settings button shows options like volume, wireless networks, etc. Most of these are also available on the Desktop, just like on Windows 7.

The most impressive feature however is the Share button. The function of this button differs depending on what you’re doing. Let’s say for example that you’re reading a cool article on your favorite blog. Click the Share button and you can immediately share the article with some friends using the Mail application

At the moment this Share option only works on Metro apps, developers can build in the Share possibilities themselves.

Another feature of the Start screen that is completely new is the Store. Windows now has an online store where you can download apps. These apps are called Metro application and can only run in full screen or snapped next to another app. When you download an app from the store you can rest assure that the app is thoroughly tested on performance and capabilities. No viruses, spyware or other scary stuff in those apps, only clean good running apps.

A side note on Metro apps: a bunch of them has a so called App bar, just right-click in the app to bring it up. Since those applications run in full screen there is no close button. The apps can be closed by pressing Alt-F4 or by dragging the app from the top of the screen (where the titlebar would be in a normal app) to the bottom of the screen.

Now pay attention class, the next part could be important. The Metro applications can be closed if you want to but why would you? Windows 8 Metro apps work a lot like iOS and WP7 apps. When you press the Windows button on your keyboard you go back to the Start screen and the application itself stays in memory in a so called Tombstoned state. This means that it utilizes a bit of memory to keep alive but uses no CPU. If Windows notices that it doesn’t have enough free memory it will start closing the oldest tombstoned apps. I’ve told you that all Metro apps are tested by Microsoft, this includes a memory test that makes sure that an app doesn’t utilize more memory then is allowed. So please consider using the tombstoned state, Metro is designed this way and stop ranting that Metro apps can’t be closed because they can but they shouldn’t.

With that I would like to conclude this post. I hope I’ve shown you that Windows 8 is really worth looking into and that it’s a huge step forward. Microsoft is going for unity among platforms, the so called 3-screen strategy where phone, pc and television (Xbox360) all work in the same way. If you ask me why I like Windows 8 so much the answer would be because it changes everything and nothing at the same time. Everyone can keep working like they always have but the changes they’ve made are all made to make everyone more productive. And it works.

My final message: Stop saying that Windows 8 sucks. Install it on a VHD, second partition or second hard drive and use it for at least 2 weeks for all your daily work. That is the ONLY way to get a decent view on how it works. And please, do not install it in a virtual machine, make 2 clicks and rant on every forum you can find about how you don’t want the Metro UI.

Make your WP7.5 app run on low-end devices

by Nico

On MWC the first Windows Phone Tango devices were announced. The Nokia Lumia 610 and the ZTE Orbit are low-end devices running on only 256MB of RAM. This is made possible thanks to a new, lower end version of the Windows Phone platform. Developers need to make their applications available for either low-end or high-end devices or both. This is determined by the memory usage of the application and if it’s set in the manifest file. Since the new devices only have 256MB of ram your application can use a maximum of 90MB according to the developer guidelines. The memory consumption of your application can be tested with the marketplace test kit by right clicking on your WP7.5 project in Visual Studio 2010.

The refresh of the WP7.1 SDK includes a second emulator running on the low end version of Windows Phone. With this developers can now test if their applications will keep running on the cheaper devices. If not, the user will get an error when trying to install your application stating that it won’t run on their low-end device. Users with a mid –or high-end device can keep using your app without any problems.

This is in fact the same emulator but running on a different image. After installing the update you won’t be able to launch the emulator from the Windows start menu anymore, to fix this add either –256 or –512 to the shortcut depending on what image you want to load in the emulator.

With that, let’s dive into some code and figure out what we can do on the low-end device.

I’ve created a demo project that on launch checks for the available amount of memory using a Device Extended Property from the new SDK called ApplicationWorkingSetLimit. I’ve poured this into a method that sets a private boolean to true if it’s a low-end device

Code Snippet
  1. private void CheckWP7Version()
  2. {
  3.     //check if the device is low-end
  4.     long result = (long) DeviceExtendedProperties.GetValue("ApplicationWorkingSetLimit");
  6.     if (result < 94371840)
  7.     {
  8.         isLowEndDevice = true;
  9.     }
  10.     else
  11.     {
  12.         isLowEndDevice = false;
  13.     }
  14. }

Note that the ApplicationWorkingSetLimit is a hardcoded string, so be very careful of typos. The 94371840 is the maximum amount of bytes my application can use on a low-end device.

Another limitation of Windows Phone Tango is that it currently does not support background agents and that includes both periodic tasks as well as resource intensive tasks. When you try to add a background agent on a low-end device you get this:

That’s not a very clear error message is it? The inner exception doesn’t tell us much more. This will probably change once the new SDK is completely finished. So when you’re using background tasks in your application, please update your app with checks of the version. Don’t submit the update to the marketplace just yet because the current CTP version of the SDK doesn’t have a go-live license so it won’t pass marketplace certification.

My example is an app that will set a random count to the application’s tile if it’s pinned to the start screen. In debug mode it will do this every 30 seconds. When you install it on the 256MB version of the emulator it won’t be able to register the agent, in fact it won’t even try because I have a build-in check for low memory devices.

In my example I’ve used a boolean to store whether or not the device has low memory. This works because my app only has one page. In a real life application it would be better to store this into the IsolatedStorageSettings using this code.

Code Snippet
  1. private void CheckWP7Version()
  2. {
  3.     bool isLowEndDevice;
  5.     //check if the device is low-end
  6.     long result = (long)DeviceExtendedProperties.GetValue("ApplicationWorkingSetLimit");
  8.     if (result < 94371840)
  9.     {
  10.         isLowEndDevice = true;
  11.     }
  12.     else
  13.     {
  14.         isLowEndDevice = false;
  15.     }
  17.     if (IsolatedStorageSettings.ApplicationSettings.Contains("IsLowEndDevice"))
  18.     {
  19.         IsolatedStorageSettings.ApplicationSettings["IsLowEndDevice"] = isLowEndDevice;
  20.     }
  21.     else
  22.     {
  23.         IsolatedStorageSettings.ApplicationSettings.Add("IsLowEndDevice", isLowEndDevice);
  24.     }
  26. }

And load the value anywhere in your application again like this

Code Snippet
  1. var isLowEndDevice = IsolatedStorageSettings.ApplicationSettings["IsLowEndDevice"];

If for some reason your application can’t run on low-end devices you can block those devices from downloading it. To do this you need to add some lines to the application’s manifest file, right below the capabilities.

Code Snippet
  1. <Requirements>
  2.   <Requirement Name="ID_REQ_MEMORY_90" />
  3. </Requirements>

With this in place the low-end devices will get a message stating that their device is not suited to run your application.

I hope I gave you a good overview about what to expect with the new low-end devices and that you can adjust your applications to support these devices. Don’t be too worried about the memory limitations on the new devices, Microsoft scanned all available applications and found only 5 that utilise too much memory, they’ve contacted the developers and are working together with them to overcome these problems.

The solution of my example can be found here(SkyDrive link).

BlockAddiction V2.0 online now

by Nico

Version 2.0 of BlockAddiction has passed marketplace certification and is available for download now. The biggest change is the all new Time Attack mode where you have to survive for 60 seconds and score as high as possible. Game Over means no score.

BlockAddiction has reached well over 400 downloads and is available on Windows Phone marketplace (Link).

I was thinking about an About page and advertising but I figured ads could ruin the experience and I completely forgot about the About page. Glimlach I might add it in the future but for now my focus shifted to some other projects.

If you’ve got ideas, bug reports or some other feedback, leave a comment, contact me via Twitter or send me a mail!

Windows 8–the road so far

by Nico

So it’s official, the Windows 8 beta, nicknamed Consumer Preview, will hit the worldwide web on February 29th. Time to list what we know so far.

For consumers:

  • the classic start menu has been replaced by a Metro interface, still unsure if there will be an option to bring back the classic menu
  • the windows desktop has now been extracted from the kernel and is just an app
  • Windows 8 utilizes much less resources then Windows 7, allowing it to run smoothly on weaker hardware
  • boot time is impressive, it takes mere seconds to launch. The cause is the fact that Windows 8 doesn’t shutdown completely, it’s kernel goes into hibernation. When you do a hard reset of the device you’ll notice that booting takes more time but it’s still noticeably faster than Win 7
  • Windows 8 will have two types of applications, the classic ones like we know them on Win 7 and Metro style applications. These Metro apps run completely full screen, no chrome like titlebars or borders
  • Metro apps run either full screen or snapped, running side by side with another app (even desktop apps)
  • Windows 8 comes with it’s very own Marketplace. Here you can download all kinds of Metro style applications
  • the ribbon that has been in Office since version 2007 now makes it’s way into the Windows explorer but it will be collapsed by default
  • Pinball and solitaire are installed games by default. Available in the store at launch will be:
    • Hydro Thunder
    • Toy Soldiers
    • Reckless Racing
    • Angry Birds
    • Ilomilo
    • Rocket Riot
    • Full House Poker
    • Tentacles
    • Crash Course
    • Ms Splosion Man
    • Wordament
  • Following apps will be included in the Consumer Preview
    • Camera
    • Messaging
    • Mail
    • Calendar
    • SkyDrive
    • People
    • Photos
    • Video
    • Music
  • Win 8 will be available on x86/x64 cpu’s and for the first time on ARM, mostly used in tablets
  • ARM versions of Windows will have both desktop and metro interface and comes with Office 15, a new Office version
  • Your profile (settings, wallpaper, …) will be synched to skydrive so that every time you buy a new Win 8 pc you don’t need to set everything manually
  • Refresh and Reset options, a refresh will keep all files and folders but will put Windows back in a fresh installed state, removing all installed applications and settings while a reset will do the same but also deletes all files and folders for all profiles
  • native USB 3.0 support
  • Windows 8 can mount and browse ISO and VHD files
  • UEFI Safe boot to prevent boot sector virusses
  • full backwards compatibility

For Developers:

  • anyone with XAML experience will be able to build Metro apps
  • Metro style takes a lot of the concepts of Windows Phone 7 and Silverlight
  • Instead of using the dreadful Win32 API developers can now use WinRT which provides a much cleaner way to interact with the OS
  • Metro apps are NOT .net code
  • .net 4.5 is included in Win 8
  • Metro apps in C#/VB/C++ + XAML or Javascript + HTML


Windows 8 will be pretty different compared to win 7. The developer preview has been out since September and I’ve been using it on a Iconia Tab W500 tablet since December. At the time I started using it I also had an iPad 2 but there’s just something special about a full blown OS on a tablet device, especially when running Win 8. I like the OS so far. The developer preview has lots of bugs, obviously, so I’m very curious about the performance and stability of the Consumer preview. Due to the stability problems I haven’t spend much time developing metro apps, this will change with the consumer preview. I’ll probably start by converting my WP7 apps to Win 8. More about that when I get to it.

Windows Phone 8, first official details!

by Nico

A video of Joe Belfiore detailing Windows Phone 8, codename “Apollo”, to Nokia has been leaked. The video has a bunch of rumors that are confirmed and some new features that will find their way into Microsoft’s next mobile OS.

The new features are:

  • Data Smart: your phone being smart about what network to use, this includes support for carrier wireless networks.
  • App-to-App communication. WP apps are sandboxed, in WP8 apps will be able to communicate with each other on a lower level then deeplinking by utilizing some sort of contracts.
  • Internet Explorer 10 Mobile. next gen mobile browser, based on the IE10 desktop kernel
  • Shared components with Windows 8. The kernel, multi-core processor support, sensor fusion, security model, network, and video and graphics technologies are all coming from Windows 8.
  • Companion experiences with Windows 8. the xbox companion app will be integrated into the system. Skydrive will have a deeper integration. All this will give the possibility to share content across phone, pc, console, … Also Zune will make place for some sort of new ActiveSync client, ow yeah! As much as I like Zune, activesync is just better.
  • Skype app. Still a separate but better app and not integrated into OS.
  • NFC and Wallet. Google wallet but coming from Microsoft, so obviously the same but better Glimlach Up to the carriers if they’ll support it. It will work both from build-in NFC chips or by special sim cards that have an on-board NFC chip
  • Local Scout. Now with personal recommendations and support for carrier hotspots.
  • Camera improvements. more powerful experience and some sort of “lens” app, we’ll have to wait and see what this means.
  • Business features. WP8 is targeting the  business again with features such as complete bitlocker encryption, secure boot check, system center integration, Exchange activesync policies and inventory possibilities. And, and this one’s kinda big, private appstores for businesses! That’s right, your in-house, employee only apps can be hosted on a private store.
  • For Developers: the CE kernel is boosted out in favor of the Windows 8 kernel, WP7 apps will be fully backwards compatible. With the new kernel comes support for native code, C++ developers rejoice! This makes porting ios and android apps easier and will make certain very popular apps finally come to our beloved platform.
  • Hardware: 4 resolutions, swappable SD card support, multicore CPU, NFC.

In my opinion, if Microsoft can deliver these features WP8 will be HUGE! This makes the Windows Phone platform on par with the competition and on some levels it exceeds them. Big kudos to Microsoft for making this happen in about 2 years, both Apple and Google have spent over 5 years to get to these kinds of functionality. Only two things remain in the dark, will our current devices get an upgrade? And will they pull this off? WP8 is rumored to roll out in the 4th quarter of 2012.

And remember Joe Belfiore, nothing remains hidden on the internet.
