Here’s a great contest for those of you thinking about publishing Windows Phone applications that take advantage of the new Mango features.

For every new Mango app you publish, you’ll receive 1 entry into a raffle for a Samsung Series 7 slate PC.

Publish 5 new apps, and you’ll earn an entry towards winning free advertising for one app of your choice.  The free advertising will run on the Windows Phone Application Network for about 60 days and include 25K impressions.
