Microsoft is partnering with Twilio to offer a contest for developers who build applications using Microsoft's Windows Azure platform. The best application will win a Dell Mini 9 netbook, a copy of Windows 7, and $500 in free Azure usage. This week's contest category focuses on Twilio apps built using Azure, and the winner will be announced by the end of the day. To help get started, Microsoft has shared an example application called the CIA Pickup that was built by Steve Marx from the Windows Azure team. The contest is part of a larger effort to encourage developers to build innovative applications using Azure.
