You may have not heard of Project Hawaii before but it’s Microsoft’s program in which they are investigating how they “can use the cloud to enhance our use of mobile devices”. The platform consists of Windows Phone 7 and several cloud services, including Windows Azure, Bing Maps, and Windows Live ID.
Microsoft has released Cloud Services SDK for Windows Phone 7 which allows for Windows Phone application creation. Applications created in such manner “leverage research cloud services not yet available to the public”, supporting Project Hawaii being the primary goal. If you’re a developer and find this appealing, head over to the source link and download the software-development kit.
