We're inside the venue at Microsoft's Windows Phone developer summit in San Francisco. From the look of the posters we're in for some new features, including some facial recognition goodness. Vivek did an awesome job covering the Windows Surface announcement in LA just two days ago, now we are just a short wait away from seeing what Microsoft has in store for the phone side of things. 

We've just taken our seats inside the venue, there are a few tablets on display along with the familiar Windows Phone interface on display. Things should be getting started shortly here.

The event is underway and we're seeing the usual assortment of positive praise quotes for the platform from press and reviewers. Some stats have flashed by, over 90,000 Windows Phone 7 applications on the market. 

Windows 8 is the subject now, and Microsoft is ready to preview Windows Phone 8. On the Amazon wireless store, 7 of the top 9 reviewed phones are Windows Phone 7 devices. Microsoft feels that its platform is still a breath of fresh air compared to other devices and platforms. 

Today is Microsoft's Windows Phone 8 platform preview. Joe Belfiore is now talking about how Windows Phone 7 is based on Windows CE and how the platform could benefit from an upgrade at the core. Common code will now be shared between Windows 8 and Windows Phone 8. That means a shared kernel between Windows Phone 8 and Windows 8.

This is a huge amount for developers in terms of being able to have a smooth transition for applications between Windows 8 and Windows Phone 8 - hopefully this means shared application spaces between the two. This also enables the hardware developers and SoC vendors to develop their drivers once and share that between desktop Windows 8 (Windows RT) and Windows Phone 8. 

Dual core is now supported thanks to the shared kernel. Joe says that the work being done on the Windows kernel focuses on dual core, probably the scheduler for really using those multiple cores in an efficient manner. Higher screen resolutions are also supported now, including both WXGA (1280x768) and 720p in addition to the traditional WVGA (800x480). All of the existing WP7.5 applications should run fine on the new higher resolutions. Removable microSD support is also a new addition, this is something I know many shoppers wanted when WP7 initially launched, and although you could do it with some of those early devices, because WP7 setup a JBOD it was never upgradeable without a complete format. Now users can expand storage after the time of purchase easily. 

As rumored, IE 10 is now integrated into WP8, with a 4x faster JavaScript engine and 2x the HTML5 support. I look forward to checking both of those out to see what exactly has changed. Joe just showed off SunSpider numbers, looks like around 1250 ms for WP8 on what I would assume is a dual core platform. 

Next up is support for native code on a common platform between WP8 and Windows 8, with access to DirectX (Direct 3D?) APIs. This should enable much better gaming experiences than the XNA games we saw before on WP7. 

NFC also gets support in Windows Phone 8, there's a demo coming with some of what that means for sharing from the OS. Along those lines is a wallet experience, which seems to be the big thing every platform is adding this next cycle, for tap to pay and loyalty cards. Devices with the SE embedded in the SIM can be used to make those tap to pay tokens work. 

Nokia maps are also getting added into WP8, including Nokia's Navteq mapping data, all of the offline support, and full turn by turn directions. Nokia's mapping experience on the Lumia series is excellent and has steadily improved, and this will be excellent for the rest of the WP8 platform. 

Secure boot enabled by the shared windows kernel is the next feature, including encryption and better managment for system administrators and enterprises. No doubt the same management tools that work with Windows 8 will work with WP8. 

Start screen is the next topic - Microsoft is changing the start screen. Tiles can now be resized and customized in new ways. It looks like there are a number of new shapes instead of the previous 1 wide and 2 wide sizes that were in WP7. 

The new live tiles are getting shown off on a prototype Nokia dual core development device with a high resolution display. Applications tiles on the home screen being shown off are normal WP7.5 apps, which looks promising. 

IE10 features including unsafe website reporting is now on Windows Phone 8 as well. HTML5 and JavaScript performance is next up, with the IE demo "fountain of apps" running at around 30 fps via hardware acceleration of the HTML5 canvas. This gets shared from the desktop IE10. 

The DirectX MarbleMaze game SDK sample which comes from Windows 8 also is being shown off running on Windows Phone 8 with what Joe says are very minor code changes. 

Tapping a Windows Phone 8 to an NFC tag containing contact data results in a toast, and easy import into the address book. Likewise using the sharing menu and NFC, two phones can be tapped together and exchange content.

Some of the wallet features are being shown off, including the wallet UI. Third party applications can expose info through WP8 which shows up in the WP8 wallet automatically. 

There's now talk about just what gets shared, and an explicit mention about the Windows Kernel being that shared component between WP8 and Windows 8. That includes the windows drivers, which should help SoC partners dedicate more time to optimizing just one driver and pusing that out to the entire WP8 ecosystem. For networking, IPv6 and better bluetooth comes along. Direct3D and better media playback and record also come over. Native code support and more .NET engine (same as the Windows desktop) also come over. 

Microsoft is really stressing the gaming experiences that will get enabled using native code (C++) and Direct3D on Windows Phone 8. Havok will bring its full engine to WP8 and enable better physics capabilities for game developers. The havok demos shown off looked pretty performant and included the same kind of destruction physics I think we're all used to seeing on the desktop. 

We're seeing a lot more detail now on the features and APIs which are being added in WP8, including SQLite (finally!), improved multitasking support for VoIP applications, and what APIs get shared between the form factors. 

Microsoft just emphasized that it has had the ability to launch applications using Speech since day one, making a subtle dig at Siri. Voice prompts in application contexts are now exposed as well for developers. The demos just shown off included conversational contexts inside applications instead of with a first party function outside of the app.

Finally some talk about compatibility. Applications from WP7 will run on WP8, and every WP7 and WP8 application will be compiled in the cloud for developers automatically.

Three real program approaches are now supported in WP8 - XAML with C#/VB, native C/C++, or HTML5/JS webapps, there's some cross compatibility thankfully so developers can use multiple things if necessary. For building applications across Windows 8 and Windows Phone 8, Microsoft has a few guidelines. Apps using the first one (XAML with C#/VB), games on a native codebase (C++/C), and simple mobile web apps should target the last one, HTML5/JS. I should note that the HTML5/JS applications are not the same kind of Windows JavaScript applications that we were shown on the desktop Windows 8. 

For businesses, WP8 adds an enterprise business hub, which can be customized with applications recommended for that particular business, alerts, profile, and other highlights. 

Windows Phone 8 hardware is up next, and launch WP8 phones will come from Nokia, Huawei, Samsung, and HTC. Most notable is that all of these launch devices will be powered by Qualcomm SoCs, so it appears that Qualcomm is still exclusive for now.

Updates now can take place over the air (OTA) and are supported for 18 months at minimum. I'm excited about the next point, which is an expedited update rollout program for registered customers and enthusiasts, this is awesome since waiting for that OTA push is excruciating at times.

Microsoft finally announced that existing WP7 devices will not get updated to WP8, instead they'll get WP7.8 and a partial update feature set, including the new home screen with customizable live tiles. Microsoft considers the new home screen the "marquee" new consumer feature in WP8, 

Updates are coming to the Lumia series next week, and to the rest of the world over the coming weeks. A DLNA application, Nokia Counters (data monitoring application), camera enhancements and extras, and a few others. 

The Windows Phone Marketplace is now up to 100,000 applications, and all those will run on WP8. That looks like a wrap, we'll see what else there is in store for us today shortly.

    WVGA isn't really cutting it anymore in the high-end space. Reply

    Seeing as they didn't read this article, I doubt your response will be read either. Reply

    Looks similar to their market share lol. Reply

    Hi please postt a full fledged article on Windows Phone summit. Also ask Microsoft about if current devices running windows phone 7.5 (like mine) can be upgraded to Windows Phone 8. Reply

    Based on how much of this is hardware-dependent, it seems unlikely. Reply

    lol now Windows Phone fan boys can't dis Android for fragmentation. Reply

    They can and will! Reply

    Why not? It's like saying iOS is fragmented because the 3G can't run iOS 5.0. I'm assuming because of the change in kernel and the switch to multi-core processors, it's not so simple to just make everything run WP8. Legacy hardware not getting the new OS is just not that surprising.

    Android fragmentation is a way bigger problem, every manufacturer has a different implementation and a different update cycle, which are two problems that Microsoft doesn't face.

    At the current development pace of smartphones and tablets, sadly, fragmentation is just a reality. The original iPad and some iTouches won't get iOS 6. If even obsolescence is a guarantee, it's in this segment of the industry. Reply
