Microsoft has made the official announcement on Windows 8. As demonstrated at the D9 conference, Here are the key points:
1. A touch-centric new interface for apps
2. The spartan tile-based Metro user interface of Windows Phone 7
3. Impressive scalability of the apps, you can even pull in an app from the side of the screen and sit it side-by-side with another running app
Classic Windows desktop apps: They will run and look similar to Win 7 today.
Now there are some questions from a developer point of view:
1. What does Windows 8 mean for .NET developers?
2. Is HTML5 the main way to write apps for the new shell?
3. Will IE keep supporting Silverlight/flash/WPF?
4. Will Windows 8 support Windows Phone apps?
Why HTML5, Not Silverlight:
They are stressing HTML 5 because they are trying to attract app developers. Today, Most of client-side developers are building HTML apps, another big number are writing iOS and Android apps. Learning XAML/Silverlight technologies is difficult. As they are losing the battle with iOS/Android, going HTML could be their only option to regain the market.
Many Silverlight and .Net developers fear their skill sets may become legacy ones. Microsoft officials have not clarified where .Net fits in the Windows 8 world.
There is a long discussion over on the official Silverlight forum fretting over the demonstrations.
Channel 9, another Microsoft developer forum, has a similar reaction
Microsoft is turning the Windows desktop into a web browser and is going in the way of Palm webOS.
HTML5 + JS for Windows Apps, Does it mean Windows app using.NET is going to dead? Share your thought in the comment box.
