The Xbox One has been available to the public at large for quite some time at this point, but the console has been somewhat lacking in regards to the apps on it. Microsoft have been rather secretive regarding the apps for their new platform, but a report from The Verge seems to suggest that these apps will be rolling out as soon as this summer.
Set to speak at their Build Developer Conference in April, Microsoft are expected to detail their plans for the apps that will appear on Xbox One including the ability for developers to turn a retail build of an Xbox One into a development kit.
At the minute, app development for the Xbox One is reserved for a specific group of developers, but this new program that they’re running will open app development up to a greater audience. The report also says that some apps will be able to play music in the background while the Xbox One is in use. Please note that one should take this report from The Verge with a grain of salt unless we get a confirmation from Microsoft themselves.
