|Windows 8 - the Developer's Take|

I-Programmer brings you the first news from Build about the way Windows 8 applications will be created from here on in.
Microsoft is currently unwrapping the "gift" of Windows 8 for us and the actual hard facts are still being dribbled out as part of a marketing presentation. You can't blame the Microsoft team, but for developers what matters about Windows 8 is not so much what we will code but how we will code.
So what is the shape being revealed piece by piece?
The first thing to say is that there are lots of shiny decorations being pointed out any one of which could make a user go "wow" and want to buy the thing. These are not what matter to developers, however.
The core architecture changes are more or less what everyone has been speculating and while Microsoft is saying that the old ways are not dead-
To quote Microsoft Windows engineer, Aleš Holeček
"We will preserve all of their investments"
but he would say that, wouldn't he.
The key ideas are that now there is the desktop and there is Metro. The desktop is where the old apps live and it is a single tile in Metro. There is a new class of applications - Metro applications - and these can be built in a number of ways. Windows is now a mobile phone but writ large. On the other hand where is Windows Phone 7 in this new architectural plan? It still uses Silverlight as its main development tool. Is it all change for the mobile environment as well or will the platforms split?
If you think that this means that Win32 has gone the way of all APIs that are no longer to be developed, then consider that .NET is also only supported in the realm of the desktop app. Surprisingly, the web browsers and HTML live there too - this really is a sweeping away of the old into a hidden corner to presumably rot quietly way. The final nail in the desktop coffin is the news that the Arm version of Windows will not support desktop applications. So if you want to write an app and you want it to work on any version of Windows then it has to be a Metro app.
As you might expect, the Build conference has lots of sessions on Metro and WinRT but none on Silverlight and few on anything that could be considered as "old technology".
It isn't that Microsoft has killed off the old technologies - Win32, .NET, WPF and Silverlight - they have simply been banished into the wilderness that is now the Desktop. In the wilderness they must surely wither because would you now start a project that targeted the desktop using the "old ways"?
