iPhones, Androids, even Windows Phone 7 devices and your old brick phones… they all had notifications to let you know if you’ve got a voicemail, text message, email, or nowadays even to suggest that your Draw Something friend has… drawn something. This all happens in the background, either on a schedule like every 15 minutes, or with a technology called “Push.” In many cases, developers need to have their own backend servers for their applications to communicate with. So how will Windows 8 do these Push Notifications? With Windows 8 development, your Windows 8 apps will use the existing Microsoft Azure servers and access the WNS (Windows Push Notification Service). In this video from Microsoft’s Channel 9, Nick Harris is here to tell you all of the details. It’s a lengthy discussion, probably more than the average person wants to know – but for geeks & developers? Some of this might be pure gold.
