Held under wraps for months, with precious few copies of the pre-release being seen, this SDK has been a long time coming. The only way to get an early look at the unfinished SDK was through hard core NDA agreements, and even these were strictly limited. One copy leaked onto the Internet, but it was extremely early and offered very few insights into the platform itself.
The official reason for delaying the SDK? It was held back due to sensitivities around “unannounced features” in the Windows Phone 8 platform (which the SDK ROM image would give away). At any rate, from today we all finally get a look in at what the future holds for apps development on the new Windows phone platform.
To jump straight into the SDK, check out the What’s new page on MSDN. If, for some weird reason, you’d prefer to read some marketing hype around the platform, perhaps have a read over here at the Windows phone site.
