Microsoft is extending the deadline for its Windows Azure category in a developer contest until September 13th, allowing participants more time to work on their projects and complete the challenge before the summer season comes to an end. The extension applies to this three-day weekend, providing a convenient opportunity for developers to get started with the Azure platform and showcase their skills. Microsoft also offers various resources, including Twilio example apps, code samples, and documentation, to help participants get started and improve their communication skills through its developer community hub, Ahoy.
