How to develop windows 10 uwp on real device (mobile)?

I faced the same problem yesterday and I solved applying this:

  • Create a Registry Key in: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SirepClient] (Probably you will need to create it)
  • Create a dword with name "DisableProtocol3" and value 00000001
  • Restart Visual Studio and try deploying the solution back again.

Registry

IMPORTANT: It's a provisional solution meanwhile a patch is included in Windows 10 mobile. We will have to consider deleting this key after that.

Solution found here.
