After setting up Windows 10 IoT Core on Raspberry Pi 2 and getting all comfortable with it, along comes Visual Studio 2015 with the message: "Please upgrade your remote debugger to match Visual Studio." which apparently means repeating the entire installation (flash from scratch) as described here http://ms-iot.github.io/content/en-US/win10/SetupRPI.htm
Is a "reinstall from scratch" the only way to currently update the Windows 10 IoT Core ? What about something like apt-get update?
