I've registered as an app developer with the Microsoft store but I'm at a loss, under devices I'm told that I need to authorize devices to use for app development but it says: "Adding additional devices must be accomplished through Visual Studio" with no added information. I tried using the 'XNA Game Studio Device Center' to add the device but it only has Zune and Xbox 360 listed, clicking on Zune doesn't help as it says no Zune device was found (since it's a windows phone 7 device I suppose that's to be expected).
So how do I add a device so I can deploy to it through visual studio?
