Useful Mango Developer Resources

With the Windows Phone (codenamed) Mango beta release, the Windows Phone team thrived to have great documentation and useful learning resources for WP7 developers.

Windows Phone Application Performance at Silverlight Firestarter

Yesterday I did a dry-run of my performance talk for today’s Silverlight fire starter. Conclusion was that the talk is like drinking from a fire-hose. It is tight for 45 minutes, but the content is good and we could not agree on what to cut. It was all too good and useful to cut stuff.  …
