Developing for Continuum poses an initially thorny question, “my phone is plugged into the dock, how can I also plug it into my PC to debug?”. My recommendation is to get yourself a Miracast device and use Continuum’s wireless connection feature. That way your phone can be plugged into your PC for debugging while casting a Continuum desktop to your monitor. If you really need a keyboard and mouse then they’ll have to be wireless too, but the phone’s virtual trackpad and keyboard are enough to get by.
