In a short demonstration over Skype earlier this week, Charla showed how easy it is to switch a retail Xbox One into one that can be used for testing UWP apps and games.
First, a user has to download the Dev Mode activation app from the Xbox Games Store. Launching the app kicks off a welcome screen and a link to documentation that details what to expect when you switch over from retail to a dev kit, as well as the requirements.
The requirements include that you:
  • Join the Windows Insider Program
  • Are running Windows 10 on your PC
  • Have a wired connection to your PC from your Xbox One
  • Install the latest Visual Studio 2015 and Windows builds
  • Have at least 30 GB of storage free on your console
