Clarifying Windows Phone 8 HTML5 Apps

If you made it to build or spent much time watching the videos one of the stories many heard from Microsoft revolved about creating HTML5/JS applications for the Windows Phone 8. Unfortunately the story confused a lot of people (at least by the questions I've been getting lately.

Let me be clear...you *can* create HTML5/JS/CSS applications for Windows Phone 8. Yup. In fact, you could do it with Windows Phone 7 and 7.5. This is how PhoneGap works. The XAML page simply hosts a WebBrowser control and loads all of the assets locally in the XAP. What you can't do is create WinJS application. Let's step back a little and explain that better.

Why Am I Excited about Windows Phone 8 SDK?

event_wp8_heroToday Microsoft is finally releasing the new Windows Phone 8 SDK. As I've been updating my Windows Phone book for this new incarnation of the device, I am excited that the SDK is finally going to be available for public consumption.

Even though the new phone has completely changed the underlying operation system to use the same WinRT sub-system that powers Windows 8, the basics of how to build apps on the phone is primarily the same. This means if you have experience building XAML-based projects, you should be right at home with Windows Phone 8.

Windows Phone 8 - What do I think?

7612.StartScreen_Maria35_thumb_7EFE7E6BSo the Windows Phone event is over and I’ve had time to digest it somewhat and read between the lines. At the time (for those who read my twitter feed), I was quite reactionary and upset at much of the news. Most of this what as a user of a Windows Phone, not as a developer of a Windows Phone. Do note that another caveat is that I am an author of a Windows Phone 7.5 book, and the thought of my book being suddenly obsolete was upsetting as well (but that happens every time one of my books passes the new car smell line). So let me talk briefly about what I think about the news from both a user and a developer on the Windows Phone platform.

The big news for most users is the fact that Windows Phone 8 won’t work on current hardware. To me this is short-sighted as it seems to punish the only fans the platform has so far. This was especially relevant since I *just* received my Nokia 900 (after having a HTC HD7 for the last 15 months). The idea that this new piece of hardware was going to be out of date in only 4-6 months upset me. But let’s think about it in broader strokes that just me. Is this a good strategy overall?

Does Silverlight Matter to Windows Phone 8?

right-HERO_MANGO_062411A lot has been made since a report from Microsoft late last week (http://shawnw.me/HPEh0R) that seemed to say that Silverlight on the phone was going away in Windows Phone 8 (Apollo). I liked a lot of what this article had to say (from e-week):

A long labor of love of mine has finally been birthed. My Essential Windows Phone 7.5 book is now available for Kindle. You can also pre-order the physical book from Amazon or directly from Pearson. While I’ve been assured that the book is printed, sometimes it can take some time to make it into the retail chain for different outlets. To clear up some of this confusion I thought it would be helpful to tell you how you can get the book depending on which retailer you go with:

40,000 Apps - What Does It Mean?

WP7MarketplaceSo the Windows Phone Marketplace hit 40K apps. What does it mean to the platform? There are a number of articles out there that talk about the 40,000 apps and compares them to other platforms but I think they are missing a key differentiator.

Articles like the PC Magazine article point to the fact that Apple got to 50K in one year (faster than Microsoft) and that it took Android in 18 months (a tad slower than Microsoft). But to me the real remarkable news of this milestone isn’t the speed…it’s the size of the marketplace for that is astounding in my opinion.

What Win8 Should Learn from Windows Phone

windows8As many of my readers know, I’ve been neck deep in the Windows Phone. More recently, I’ve been digging into Windows 8 development as well. On my most recent trip, I spent quite a bit of time with the BUILD tablet. Good news is that it’s a pretty good piece of hardware. Even though it’s not ARM, I am still getting a good four hours of battery life. This version of Windows 8 is early but I do think there are some things that Windows 8 should learn from what they’ve done with the Windows Phone. Here is a short list of what I think the team should look at on the phone:
